from the book:
Using the expertise gained from years of designing and building engines, Porsche developed what is known as the M96 engine for the introduction of the Boxster in 1996. The horizontally opposed engine was developed with a throwback to the traditionally air cooled motors, having kept the opposing cylinder or boxer layout. The engine was designed from the outset with the goal of providing a common platform for both the Boxster and the upcoming Porsche Carrera. The motor was indeed scalable, encompassing a displacement that ranged from 2.5 liters all the way up to 3.8 liters at the end of its production run.
The M96 (and subsequent similar M97) water-cooled engine is definitely a strong performing engine, however along the stages of its development it has suffered from some design deficiencies that have been identified and corrected by Porsche over the 11 year lifespan of the engine. It's not uncommon to find a car listed for sale with “new factory engine recently installed” in the advertisement. No one but Porsche knows exactly how many engines were replaced under its recently discontinued engine exchange program. However, simply swapping out a broken engine for another one does not address known weaknesses in the engine due to design deficiencies. The purpose of this project is to identify some of the problem areas of the engine and offer up solutions on how to fix and/or prevent any damage from happening to your engine.
Rear Main Seal Leaks: When the M96 engine first came out, it was perhaps most known for its rear main seal (RMS) leaks. While some of the RMS problems were probably actually intermediate shaft cover leaks (see next section), there were definitely some problems with the seals on the early cars. For the most part this was a “cosmetic” issue, as the leaks did not tend to affect performance, unless they became so severe that they began to affect the proper operation of the clutch. But many engines were torn apart and/or replaced by Porsche under warranty due to this problem because when you pay $75,000 for a high performance sports car, you expect it not to leak.
It's not really 100% clear what the causes the leaky rear main seals. One cause may possibly be the fact that the crankshaft has insufficient support on the rear end. It also may be caused by the fact that the crankshaft carrier support is only pinned minimally in one plane to the outer case. This can lead to shuffling of the carrier: shuffle pinning the crankshaft carrier as is commonly done when prepping an early 911 engine for the track can help the problem.
The seal has been updated to a 997 “Cayenne-style” part number since the engine was originally introduced, and for the most part the engines no longer leak from this area when this new and improved seal is installed. If you find that your engine is leaking from the rear main seal (also known as the flywheel seal), then simply install a new one while adding a little bit of Curil-T sealant to help keep it dry (see Photo 10 of Pelican Technical Article: Clutch Replacement).
Intermediate Shaft Bearing Failures: The intermediate shaft bearing is probably the most troublesome of all of the M96/M97 engine problems. The intermediate shaft bearing (IMS bearing), supports the intermediate shaft on the flywheel end of the motor. Porsche designed these motors using a sealed ball bearing that is pressed into the intermediate shaft. These types of bearings are typically used in devices like copy machines and other machinery used in dry conditions. In theory, the area where Porsche designed the bearing to sit is supposed to be dry. However, after years of use within the engine, it would appear that oil and contaminants from the engine seep past the bearing seal, wash out the original lubricant and become trapped inside. The result is that the bearing now operates in a less-than-ideal environment and begins to wear prematurely. When the bearing wears out, the timing chains on the engine may disengage, and the engine will quickly self-destruct. When the bearing does fail, foreign object debris from the bearing circulates throughout the engine, causing further damage to other areas in the engine.
On the early cars, Porsche also used a center bolt to secure the IMS bearing that was too weak and sometimes snapped. If this bolt breaks, then the intermediate shaft begins to float around in the bottom of the engine, and you can soon experience catastrophic engine failure.
This area is also highly prone to leaks. The seal around the intermediate shaft cover can leak, and it has since been updated and redesigned to prevent leakage. In addition, the three bolts that hold the intermediate shaft cover are through holes which exit into the cavity of the engine case. You must coat these bolts when reinstalling them in order to prevent oil from leaking out through the bolt holes. In general, if this area is leaking, it may indeed be a sign that your intermediate shaft is failing and you should inspect it immediately.
The good news is that the IMS bearing problems are all fixable, thanks in part to a retrofit kit that can be installed with the engine still in the car. See Project 14 for full instructions on how to update your engine.
Cylinder Liner Cracks: In an effort to reduce costs during production, Porsche utilized a type of insert-mold casting process to directly incorporate Lokasil cylinder liners into the case. While this is a neat way to reduce the total number of parts used in the engine, this design basically casts a wearable part into the engine case. There is no factory replacement for the liners: when they wear, the factory expects you to buy a new engine case. In addition, the design of the cylinder liners allows them to “float” within an area filled with coolant.
Excess vibration and twisting from the normal operation of the engine appears to be causing some cracking in these liners, resulting in a small chunk of the liner breaking off. This “D-chunk” problem seems to ironically occur mostly in gently driven cars. Boxsters that are driven hard at the track or on the street do not tend to see this type of damage. At least with respect to the track cars, one theory is that these cars tend to have their oil changed much more often. The problem affects mostly the 2.5 and Carrera 3.4 engines: the 3.2 Boxster S engine appears to be unaffected because it has thicker cylinder walls than the 3.4 engine. When this failure happens, you will see oil and coolant begin to mix together, or a slight unexplained coolant loss.
If your engine experiences this failure, it can be rebuilt using LN Engineering's Nickasil liners installed. They take your old case, machine out the cracked or damaged Lokasil liners and install an aluminum Nickies insert which is stronger and more reliable than the factory cast-in liner. In addition, with the installation of the liners it's fairly easy to increase the bore of the cylinders which translates into increased displacement and more horsepower. If you go this route, you will also need to use some aftermarket pistons and perhaps update the software in your DME to accommodate the larger displacement.
Engine Casting Porosity: As mentioned in the previous section, Porsche used a new cost-effective method to cast in most of the oil and water cooling passages directly into the engine case. This reduced the total part count for the engine, and also helped to reduce assembly time and production cost. Unfortunately, the advanced casting technique seems to have led to a number of engine cases experiencing what has been called “engine porosity.” There is not a lot of information available on this problem, but it seems to be related to problems with the initial casting process.
In some cases, there appeared to have been a leak through the internal crank case walls. The process of pouring the molten aluminum must be tightly controlled, otherwise pockets of air forming in the aluminum may result. Most of the time, post-casting inspections will reveal these flaws, but apparently some were still manufactured into running engines. The result is that oil and water became mixed within these engines. This resulted in coolant being found within the oil (turning it a milky brown color), or oil being found inside the coolant tank.
The expansion and contraction of the engine due to the heat of normal operation can expose this problem as well. I have also heard of engines that simply weeped a slow bead of oil right through the walls of the engine case when running. Unfortunately, there's nothing that can be done to fix this problem, short of scraping the engine. The good news is that most of these problems were discovered on the cars when they were new, and the engines were since replaced under warranty.
Chain Tensioner Failures: There's been some chatter lately about chain tensioners failing on some of the M96 motors. If your car is noisy on startup and then suddenly quiets down, it may indicate a problem with your chain tensioners. Porsche updated the design of the tensioners in 2000 (TSB Group 1 NR 8/00), and replaced them with an improved design. I recommend that you update and replace your chain tensioners if they are the older style. See Project 16 for more information on how to identify and replace them.
Cylinder Head Cracks: In general, the cylinder heads are pretty well designed on the M96 engine. However, on some 3.2, 3.4 and 3.6 engines, small cracks can sometimes develop around the seats of exhaust valves and extend to the spark plug hole. The mounting point for the cam follower housing is also a weak point. Often these cracks can lead to coolant and oil mixing together. This is not an uncommon problem with automotive cylinder heads in general and can often be repaired by a skilled machine shop that can weld aluminum heads.
Oil System Inadequacy: The air cooled predecessor to the M96 engine incorporated a dry-sump system that was designed to keep a significant amount of oil in reserve for extended performance driving. With the introduction of the M96 engine, Porsche moved away from that design, primarily due to the high cost of implementing a separate dry sump system. The M96/M97 motors instead were designed with a compromise system, which has an oil sump built into the bottom of the engine: a kind of hybrid between a dedicated dry sump system and a typical wet sump. As a result of the lower oil holding capacity and other factors, the M96/M97 engines tend to suffer more from oil starvation problems, particularly during high performance driving.
In addition to the standard issues associated with the non-traditional sump system, the flapper windows on the bottom of the engine are manufactured out of plastic, and can break off inside the sump and clog the oil pickup tube. This leads to oil starvation and complete engine failure. The solution is to remove the bottom sump and inspect the oil control windows (see Pelican Technical Article: Oil Pan Gasket Replacement / Deep Sump Installation), and replace them if they are missing or damaged. You can also add aftermarket stainless steel windows for added protection.
As mentioned previously in Pelican Technical Article: Oil Change, I do not care for Porsche's standard recommended oil change interval of 15,000 miles. The oil in engines tends to become contaminated with fuel and coolant, particularly as the cars age and seals and piston rings begin to wear. I generally like to run a thicker oil and change it every 3000 to 5000 miles. Keeping the oil fresh may help prevent some IMS bearing issues and generally prolong the life of your engine.
Connecting Rod Bolt Failures: The connecting rods that are used on the Boxster are forged out of steel and utilize what is known as a cracked-rod design. This means that the rods are forged and machined, and then broken along pre-set stress points. Then the bearings are installed and the rods are put back together again. This cracked-rod design is cheaper to manufacture, and the rod bolts don't need to have integrated "guide" pins as part of their design (like the rod bolts used on the older air-cooled engines).
Unfortunately, it would appear that the rod bolt diameter may be too small for the large loads that these engines place on the rods. A number of recent failures in some early high-mileage engines have hinted that the rod bolts are too small and may be a failure point for the connecting rod.
The failure occurs when the engine is consistently revved at the high end of its RPM range. The stock rod bolts are designed to stretch and permanently deform when tightened down to their final torque values. At RPMs of 6700 or higher, the rotating mass on the end of each rod (namely the piston and the mass of the rod itself) has a tendency to stretch the rod bolt further. Repeated stretching of the rod bolts causes them to deform and loosen up which can result in rod separation and complete engine failure.
Unfortunately, due to the cracked-rod design, the connecting rods cannot easily be rebuilt. The solution is to install aftermarket connecting rods that can accommodate larger, race proven fasteners like the ones available from ARP.
Variocam Solenoids: It's not uncommon for the variocam solenoids to fail on one side, which will result in a uneven, or lopey idle. Moisture can get into the mechanism causing it to corrode and eventually fail. The DME computer should be able to easily detect this failure and trigger a check engine light (CEL).
Paper Oil Filters: The oil filter system on the Boxster is a bit lame in my opinion. Using the stock paper filter can lead to a disintegration of the filter which can then clog the oil passages of the engine. Although this is a relatively rare problem, I have heard of it happening with cheaper brand oil filters. Stick to the good quality brands, and also consider upgrading to the LN Engineering screw-on oil filter upgrade (see Pelican Technical Article: Oil Change).
Air-Oil Separator Failures: The air-oil separator is an emissions device that draws vapors from the engine crankcase and then sends them back into the intake manifold. When this unit fails, the result is oil is sucked out of the engine and into the intake. While the air-oil separator will not cause immediate mechanical damage to your engine, it may make it smoke tremendously and / or run roughly (see Pelican Technical Article: Air / Oil Separator).
Oil Change Intervals: The best recommendation to any Boxster owner is to change their oil more often, say every 5,000 miles, as well as use a minimum 5w40 viscosity oil. On cars not equipped with Variocam Plus (2006 and earlier), use of a 15w50 or 20w50 provides a much higher film strength which will improve internal bearing life considerably.
Low Temperature Theromostat: Also useful is the LN Engineering low temperature thermostat (see Pelican Technical Article: Water Pump & Thermostat Replacement). This specially designed thermostat starts to opens at 160° F instead of 187° F for the factory unit. Keeping the oil cool is key to keeping it fresh and the lower operating temperatures also help to give you a bit more horsepower too.
This photo shows the flywheel end of an M96 motor. This particular motor is a 3.4 liter crate motor from Porsche that has been updated with the latest and greatest improvements from the factory. The intermediate shaft has the updated bolt (yellow arrow), but the issue of the intermediate shaft failures has still not been completely addressed in this redesign. Although these updated engines tend to suffer from fewer problems than the early ones, there is still a risk of IMS bearing failure. The rear main seal shown here is the updated and improved one that should not leak.
This is the infamous “D-Chunk” problem that happens sometimes on these motors. Occurring almost exclusively with the two cylinders in the middle, it is theorized that excess twisting and vibration causes cracks to occur in the cylinder walls. Found mostly on the 2.5 and the 3.4 engines, this problem is almost non-existent on the 3.2 liter engines because the 3.2 has thicker cylinder walls. The solution is to machine the case to accept cylinder liners (next photo).
Here is a fully repaired M96 engine with the LN Engineering Nickies liners installed. The case is prepared by machining out the old liner and completely removing the section that floats in the water jackets. Then, a Nikasil cylinder is press-fit into the case in its place. It's a clever solution to the irreplaceable case problem. The case itself must be a good rebuildable core and have no major issues (no major damage, no case porosity issues). In addition to replacing the liners with new and improved ones, the process allows you to increase the displacement of the engine at the same time. The 2.5 engines can be easily increased to 2.7 and the 3.4s can be pumped up to 3.6 liter displacement. There is even an option for 3.8 liter and beyond in current development.
Although it may not look like much, this crack is enough to cause a lot of problems. Cracks like these can cause oil / coolant to mix, resulting in contamination of the coolant and/or oil. Cylinder head cracks are common among water cooled cars, and can sometimes be repaired by grinding down the head and then rewelding it. Photo: Glenn
Comments: Hi Nick: I did make the trade of my 04 911 Anniv for the 2002 911 Turbo with 35k miles and love the turbo. Now, I am looking to trade my 06 BMW Z4 with 34k miles for a 2000 Boxster S with 14k miles.Car is now on Ebay, it's the burgandy one, can you take a look? After reading above concerns incl the IMS failures, etc, would the Petra Oil Platinum Warranty offer provide peace-of-mind? thanks

Followup from the Pelican Staff: I would need the VIN to determine year. can't say when and if the engine will fail. Perform maintenance and replace known problem parts before they fail. - Nick at Pelican Parts
Comments: I'm in the process of buying a 2005 Base Boxster with a 6-speed and 24K miles. The car is located about three hours from my home. I drove the car this past Saturday and it was great. I loved it and I'm excited about getting my first Porsche. The IMS issue is troublesome though. If the car runs great now and I bring it home on a trailer and drop it off to have the bearing done along with the RMS and a new clutch, should I be fairly well protected against any catastrophic engine failure? And do the 2005 Boxsters have the M96 or the M97? I heard the M97 engines need to be disassemble to do the bearing upgrade.
Thanks. Your website is great. Very informative.
July 28, 2014
Followup from the Pelican Staff: I would think so. Have it replaced asap, check for any other maintenance items and you should be good. Even with the issues, these are great cars to won. - Nick at Pelican Parts
Comments: I've got my eye on a 2002 bolster 2.7 with 84,000 miles. The carfax shows no work done related to RMS, IMS failure or some of the other big, known issues. Will have it checked out by a porsche mechanic prior to buying to determine. Question is, if a vehicle hasn't developed these problems by 84k miles does that mean it likely won't be a problem in the future? Or is it just a matter of time until these failures occur? Or another way to ask is are all boxsters of this era afflicted with these problems or just the "lemons"? Thanks
July 18, 2014
Followup from the Pelican Staff: Most of the common issues will hit all of them. Some people may get lucky from time to time, however the way I understand it, problems like the IMS are only a matter of time. - Nick at Pelican Parts
Comments: Thinking about buying a 1997 Boxster with 38,000 miles on it. Asking price is $11,900 but I think between 9K -10K is a fair price. Am I in the ballpark. Also, the car does not have the "Boxster" raised lettering on the rear trunk. Is this normal for a 1997 and if not should it be a red flag? Anything else I should look for on this car before making an offer?
July 17, 2014
Followup from the Pelican Staff: I would say it is not a red flag. I like to use kelly blue book for pricing. It's hard for to say without seeing the vehicle, what I would pay for it. - Nick at Pelican Parts
Comments: 1999 automatic boxster here, whenever I put my car into any gear, park, neutral,drive the shift requires alot of strength to pull it back. Any ideas?

Comments: 1999 porsche boxster. When i start the car in the morning i have to let the car warm up really well,after that the car runs good. without warm up i have no power and the car snaps and pop back through intake system. also when trying to accelerate quickly i have a lost of power around 3000 rpms but if i let up off of the acclerator a little the car stars to pick up speed .The car acts like tiere is a cut out to keep me from tachking out on rpms. Thank you
June 18, 2014
Followup from the Pelican Staff: Could be a timing issue, maf sensor, or fuel delivery issue. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
- Nick at Pelican Parts
Comments: at 3000 rpms the engine bargs down and will not allow me to accelerate quickly also if i dont allow the car to warm up it will pop and snap back through air intake system

Comments: Stick with early Porsche 911's ! I recommend a 81-83, 911sc, worry ot about ims failure, cracks here and there, leaking coolant, water pumps and check engine lights !!!! Bla bla bla ! No car should have that many issues until long after 100k miles! Frankly a real good mechanic with passion for Porsche who treats his clients cars like their own child and and is reasonable in price is a all you need. Almost bought a Cayman s 2008 with 29k miles and just frankly the thrills and excitement of driving these cars does not outweigh the headaches of repairing or replacing parts that should not be necessary on a car that new cost close to $60k nneding engine replacing or leaking rear main seals at 50k miles on a newr Porsche just my opinion! A911sc for $32,000 or a Boxster S, Cayman S for the same price with depriciating values a rapid pace ? The 911sc hands down better choice. Went to the unvailing of the new Porsche Macan at the dealer party and had two cash offers but nope, this beauty is going up in value as we speak! People are realizing newer Porsche are sweet and all but the roots of the early model 911's will always have the upmost respect from true enhtusiast ! Love it when people walk out of their newer 911's or late model Porsche's and come to take a pic or hand me a business card, asking if i ever want to sell it to give them a call! A decent one now is in the early $20s, find a clean early model 911 and you will own one !

Followup from the Pelican Staff: I would have camshaft deviation checked. You could have a worn timing chain component. - Nick at Pelican Parts
Comments: Note to Johnny May 25 who was bummed because his engine STB. There was a settlement in the Class Action Lawsuit against Porsche AG in which Porsche agreed to compensate for loss certain owners and lessors of Boxsters for costs related to IMS failure. Just google Porsche IMS lawsuit. Maybe it will help. Also note the Boxster 987.2 2009 and beyond doesn't have an IMS so problem solved. But with the newer cars and DFI there may be a whole new set of issues. Sometimes the tiger you know is better than the one you haven't yet met.

Comments: I presently own a 2003 Porsche Boxster S which I have driven without issue since I purchased it in 2010. Lately the car has begun to display behavior quite uncommon. Although intermittent, the symptoms are the following: difficulty starting engine requiring upwards of 5 seconds cranking, fast idle in the 1,100-1,200 range and violent shaking of entire vehicle when pushed beyond 4000RPM. There is absolutely no warning light on dash. Any clues as to the probable source of the problem? Thanks for your assistance.
May 29, 2014
Followup from the Pelican Staff: Could be a fuel delivery issue. I would check fuel pressure, volume and quality. It would also be a good idea to check for fault codes, even with the light out, there may be a pending code. - Nick at Pelican Parts

Comments: I've loved my 2004 Boxster S until IMS failure recently. I've serviced this car from new at the same Porsche dealer for all its life. 1000 k after a major 60,000 k service I need a new engine. What!! At Porsche after the warranty is over they are happy to bring all sorts of things to your attention. Replacing wipers, key button remotes,windows not closing properly and all sorts of extras, mostly trivial. But no mention ever about common major problems such as IMS that will need engine replacement..why not warn people? This is major. Just tell us, so we can aim to prevent this Porsche people. All the fuss on coffee and comfy seating and customer service. How about we get our own coffee and they tell us how not to blow our engines. I'm pissed and that was my first and last Porsche.

Followup from the Pelican Staff: Sorry to hear you are turned off on Porsche now. They are great vehicles with issues like every other vehicle. However, being a highline car repairs tend to cost more, so it can become a burden. - Nick at Pelican Parts
Comments: I have a 2002 Boxster S with 54k miles. No problems to date and all mtc work done timely. Lately I am having problems starting it? The clutch is in and the dash cycle is complete through full oil. Most of the time it starts right up, other times I have to turn key off and back on. Wait for the dash cycle to complete, and nothing happens? After 3 or 4 tries, it starts right up. No problem with battery or alternator. Any suggestions of what the problem might be?
May 17, 2014
Followup from the Pelican Staff: Could certainly be the battery. I am assuming the engine fails to crank when the problem is present. I would start by checking and testing the battery. If it is OK, you will want to check the signal to the starter motor from the ignition switch. - Nick at Pelican Parts

Worried boxster owner
Comments: I just bought a 2000 Boxster. Took it to my well respected local Indy shop and it has oil leakage. I'm having them take it apart and check/do RMS, IMS and clutch if needed. Until they get into it I won't know what's wrong. Being that I drove it in and am doing the IMS am I out of the woods or is there still a chance that when they get it apart it will be unrepairable?
May 14, 2014
Followup from the Pelican Staff: If you drove it in and the engine was running well, you should be OK. Wait for the diagnosis and repair what is needed. - Nick at Pelican Parts
Comments: I have 2002 boxster with 22,000 miles. During winter I remove battery as I don't drive it in bad weather. In spring I charge the battery, reinstall and start the car. Worked 6 years nicely until this year.
This year the key would not turn as if it were a bad key. I suspected it might be the key immobilizer function. My local Porsche dealer said it was probably the key ignition module and would need replacing. I checked all the fuses and none bad. Tried starting it with jumper cables. Nothing helped.
Then without trying to, I inadvertently moved against the seat reclining arm and I was surprised it reclined. Put the key in and it turned. ???? Lucky I guess. Hope this information helps someone.

Followup from the Pelican Staff: Hard to say without seeing the vehicle myself. Have you considered having it inspected by a Porsche mechanic? - Nick at Pelican Parts
Comments: Just finished a test drive on a 2002 911 turbo which I may trade my 2004 911 non-turbo for. The clutch pedal feel was different on the turbo, seemed to be higher engagement and much softer pushing down to floor vs my 04. Is this the normal feel/comparison on a turbo car 911 ?
April 21, 2014
Followup from the Pelican Staff: Turbo models have a slave cylinder with a pressure accumulator. It does feel different than non-turbo models. - Nick at Pelican Parts
Comments: I have a 2003 996 C4S, engine swapped at 45,000 miles, now has 78,000. I have a small leak from the back, it was diagnosed as the RMS. leak is so minimal I thought I would wait to have the clutch repaired and do repair. Questions: 1 Could my mechanic be misdiagnosing an IMS bearing failure for a RMS problem? 2When replacing the RMS, should I use factory parts or are aftermarket stronger? 3 When doing RMS, it is generally the same work that would be involved in replacing the IMSB, so might as well do it anyway, correct? Thank you so much, your company and forum have really informed me well.
April 21, 2014
Followup from the Pelican Staff: It is hard to diagnose a rear main seal leak. Your mechanic has to go by what he sees externally. A leak from an IMS and RMS can look similar on the exterior of a transmission bell housing. SO I would say it wrong to say he misdiagnosed. I would prepare to replace the IMS as well.

Comments: To Nick at Pelican: regards the 2002 911 Turbo which I posted yesterday, I am scheduled to see car tomorrow, but as I am not a mechanic, is there any general thing I should look for or question on a 6,200 mile car that may have sat idle for a stretch? Naturally I will seek to mechanic check car before buying. thanks

Followup from the Pelican Staff: If the vehicle sat, you will want to check all the rubber components, fluids and tires. The tires may have flattened in one spot from sitting, rubber dry rots and the fluids can take in contaminants.- Nick at Pelican Parts

Thinking of Boxster
Comments: A friend made me a great offer on his 1998 Boxster. It is in immaculate condition except for the 2.5L engine which was diagnosed by the Porsche dealer as having dropped a cylinder sleeve. The car still starts, but runs very rough.
I've rebuilt engines before, but I have no experience with Porsche. Since the engine still runs, I assume the sleeve didn't fully drop and cause catastrophic damage. Do you think the engine is rebuildable or does a dropped sleeve rule out any possibility of rebuilding it?
April 7, 2014
Followup from the Pelican Staff: If the sleeve dropped, the block case will have to be repaired. There are a few companies that do this. Look into flat 6 innovations. - Nick at Pelican Parts
Comments: I just bought a 2006 Cayman S Auto with 40k on it. Since i got the car 3 weeks ago, i noticed some "issues"...below are the 3 key ones i hope to get better clarity on. Tks in advance.
1. Car has white smoke when i am warming up the car and exhaust has strong gasoline smell. Told my mechanic it could be AOS and he disagree - he said if there are white smoke as the engine is hot, that could be AOS issue, but mine is only when the engine is being warmed up. Ur thoughts on the white smoke and the strong gasoline smell?
2. My engine oil level is also dropping approx. 0.5 litre gone on 800km of driving. Could be related to question 1.
3. On idle, car seems to vibrate slightly. It feels like sitting in a modified Subaru WRX which i used to own. Could it be the flat six layout or a problem with my car?
April 7, 2014
Followup from the Pelican Staff: The oil consumption amount can be considered normal. WHite smoke at start up can be condensation.
if you have an engine misfire, you will want to pinpoint the cylinder. Then check spark, fuel and compression on that cylinder. - Nick at Pelican Parts
Comments: I have a 98 boxster. When I use my remote to open and close I have to hold the remote next to the drivers window. Anywhere else no go. Also I have to put battery on trickle charge 24/7 otherwise car won't start after a few days. What causes the battery to go flat. ?
April 6, 2014
Followup from the Pelican Staff: You may have a parasitic draw. You'll want to monitor the draw on the battery when the vehicle is asleep.
Once you confirm there is a draw. You will have to isolate the circuit with the draw. Then determine which components on that circuit is causing the draw You can isolate by removing fuses. be sure to have all the latches on the doors and hood closed (pin switches) so the vehicle will sleep during testing. If it wakes up, you will have to wait until it goes to sleep again. - Nick at Pelican Parts

Comments: I thought I'd read everything there was to read on Boxsters issues until I found you guys....I have most of the paperwork on mechanical issues and servicing preformed on the the Boxsters I recently purchased. My question is, " is there a way to tell if the RMS or IMS issues have been taken car of on this car by looking?" Without a paper trail? It's a 99 with 61k on it, starts great, drives very well and just seems to be in great I mechanical condition...I purchased from a Porsche dealer. Major services were just done at 60k as well....clean with no leaks, I've probably driven around 1000 miles on it. I bought a new 911 in 84, drove for many years with no problems.....
March 30, 2014
Followup from the Pelican Staff: You would have to remove the transmission and inspect the part. So without a paper trail, hard to tell if it has been done. - Nick at Pelican Parts
Comments: 15W50 or 20W50 oil for 2006 and earlier 987 Boxster S?
I have never heard of anyone using this oil - it's usually always 0W40 with some like me running 5W50 during hotter months.
15W50/20W50 is not an oil weight that anyone I know has ever used on these cars? What about winter months in colder areas Colorado - a 15W even worse a 20W would likely cause more damage to the engine every time a cold start in sub-zero temeperatures!
Would love to hear more theory on this advice - if anyone else can chime in and state that these weight oils is absolutely more protective to my 987.1 2005 Boxster S, I'd love to hear the theory!

Comments: Greetings from Australia,
I was about to purchase my first porsche boxter and accidentally I've found your web site. Thank god I did or maybe not?
Just a quick question.
2006 987 boxter MY07- does it also have issues with the intermediate shaft bearing IMS bearing? Any other issues I should look out for?
Cars on Australia are 45% dearer than anywhere else in the world. So if you guys in states say replacement engine cost around $20k here would probably be double.
I'm looking at those cars. I think one is auto the others manual. Any advantages or disadvantages over the two gear boxes? Does auto means more problems or manual means expensive clutch replacements. I think there is one MY06. My favourite is for $43 silver with 57,000km.
I know you're probably laugh thinking this poor fucker is going to spend $40k on a boxter we wouldn't pay more than $20k in US. I also can't afford having to spend another $20k or $30k on a new engine.
I'm a middle class hard working separated middle life crisis 37yrs old guy who is going through marriage break up and needs a toy to enjoy or he will loose his sanity.
Followup from the Pelican Staff: 2007 models still have issues, but the bearing is not serviceable without engine tear down. I would say go for the manual transmission vehicle. Clutches are easier to deal with than suto trans issues. - Nick at Pelican Parts

Comments: My 2001 boxster developed a "turn over/no start" problem. I would drive normal, park for 15 -30 min. and get it to turn over but not start. I waited for about an hour, tried again and it started normally? I developed a routine of letting it sit for at least 45- 60 min. and get a normal start. replaced the fuel pump relay with no fix. next thought fuel pump. Replaced it and again no fix. took it to my porsch dealer. It turned out to be a "intermittent fault in the crank sensor". replaced it, all is well now. that simple fix took a long time to isolate the fix and $800 later.

The car starts right away at lower temperatures or after sitting for a short time, but cranks for 10 - 15 seconds after sitting at higher ambient temps before starting. Looking for ideas on how to diagnose or resolve as summer is approaching....
March 4, 2014
Followup from the Pelican Staff: Could be a faulty sensor or DME output.
I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

Comments: I have a 2008 Boxster S with a surging problem. Staring at around 1800 rpm, up to about 2200 rpm the engine will surge about 200 rpm while accelerating. it does not happen outside this range, but it is consistent and throughout that rpm range. The car now has 65K and it has been becoming more pronounced. The dealer reports "cannot duplicate' and there are no reported fault codes. It is my daily driver and I just love the car!
February 22, 2014
Followup from the Pelican Staff: The surge can be from a fuel delivery issue, vacuum leak or air intake issue. If the problem cannot be duplicated in the shop, you may have to wait until it becomes more pronounced. Intermittent issues are hard to diagnose, and the lack of fault codes doesn't help. - Nick at Pelican Parts
Comments: It is so crazy to think that a modern Porsche Boxster would have so many serious issues. Engine replacing? Best sugestion for any Future Boxster owner in my book would be, stay away and invest in a well maintained daily or weekly driven 81-83 Porsche 911sc or any 930 at that and you will have many many years of headache free memories!!! I have seen well over 200k miles on early never rebuilt Porsche 911's satisfying their owners every time they drive ! Newer modern not always means better !

Followup from the Pelican Staff: The 911SC I bought for the 101 Projects book I wrote had seven broken head studs. Every engine since about 1968 or so (with the layshaft problems) has had issues. 911SCs also suffered from chain tensioner failures too. So, each engine did indeed have it's own problems. The Boxster is no different, and it's fixable just like 911SC head studs, and chain tensioner issues. - Wayne at Pelican Parts

January 8, 2014

Comments: Hi Wayne I have been a g standing owne, 15 years 924/944 and 12 with 911s. I bought a 2000 Boxster S 68k with a noisey top end with oil burning issue. I have stripped out the left nk cams and all of the followers have collapsed. I have submerged them in oil ut they will not prime. The oil pump seems to work when turned submerged in oil and the plugs in the end of the cams are present. All looks clean with no wear or debree. The car was serviced 2 days before the failure. Before I replace the followers is there anything else I should check. There is a fair bit of oil between the engine/gearbox area all around but the torque converter looks dry both sides from the little I can see.

Followup from the Pelican Staff: I am not sure what is covered on your vehicle.

Comments: Hello I have a 1999 Boxster with 37K miles. It has worked great until we got P1324 Camshaft position with respect to crackshaft bank 2 exceeds limit value, P1387 camshaft position sensor bank 2 short to ground and P0304, P0305, P0306 which are misfires on all cylinders in that bank. I now have a rough idle due to the misfires. I have replaced the spark plugs and coils for that side. According to my durametric my timing is off on that side by 25 degrees. Is it possible that a bad solenoid could cause that or could it be the variocam tensioner for that side. I have access to a used engine that i had from another boxster so I can get the veriocam and sensor from that one but I wanted some opinions before I tinker further. Thanks, David A.
November 4, 2013
Followup from the Pelican Staff: An actuator could fail, but I see more mechanical timing issues. The misfire also makes me think it is a mechanical issue. I would check mechanical engine timing. Use camshaft locking tools to lock the engine down and see if it is properly timed. - Nick at Pelican Parts
Comments: I just bought from a local independent dealer a 2004 Boxster 2.7L 5-spd w/ ~70,000 mi, confirmed the IMS had been retrofitted, and had a new clutch. Car leaked oil from Day 1, stalled when coming to a stop with A/C on, and had unusual engine noise after an hour of driving. In the shop and out the first two months no charge from dealer but continuing problems until finally the big one: cylinder bearing gave way and spun the crankshaft, damaging it irrevocably. They tried to get it machined, no luck. So choices are: 1- Demand my money, or most of it, back no warranty; 2- Go with their recommendation to put another used motor in; or 3- Have them replace the crankshaft, seals, oil pump, etc. with new parts and put my motor back in. They say the rest of the motor is perfect and they have cleaned it up completely. They are balking on the new crankshaft because it is so expensive. I am leaning towards Option #3 because I am not confident that another motor out of a crashed car will not come with major problems of its own, and I'll be at risk. The dealer has mentioned using parts from Pelican. What is your "impartial" recommendation?
October 15, 2013
Followup from the Pelican Staff: This is a tough call. When there is a major bearing failure the engine oil passages can be filled with metal debris. This can lead to future failures if the engine is not completely torn down and cleaned. I think the rebuild or a used engine is a good choice. That is if they perform the rebuild correctly. If you are not confident in their ability, ask then if they would pay for a shop you trust and have a relationship with to perform the repair. - Nick at Pelican Parts
Comments: I NEED HELP
I have a 2000 boxster 2.7L M96 5 chain motor with 30,000 miles on it. Recently the car began to idle rough and the Check engine Light CEL came on. The OBDII code was P1341 related to vario camshaft adjuster. Pulling off the cam cover, and removing Bank 1 camshafts we found that the cam-adjuster plunger was stuck which is probably why the car was idling rough. The larger concern was that we noticed that one bearing surface on the intake camshaft on cylinder 3 near the chains was very rough and worn. All bearing surfaces were very clean and smooth exempt this one see picture.
• Q1 - Anyone know what would have caused this?
• Q2 – Suggestions on how to fix this bearing surface on a the head and b the camshaft bearing cap?
• Q3 - How to prevent this from happening again?
This is a weird one and need any HELP / suggestions you may have!!!!
October 7, 2013
Followup from the Pelican Staff: This is from an oiling problem or debris in the engine oil. I would inspect the oil filter element for metal or debris. This could be from a failing bearing in the engine, putting small metal pieces in the engine oil. Looks like you will need a new cap and camshaft at the minimum. Hopefully you caught it early enough. - Nick at Pelican Parts

I see ton's of issues with the 2005 and older models here and have some hope that the 2006 is much better with the revised bearing. I know the 2009 design is much better but the cost is twice as much for the vehicle. Thoughts on the M97 engine reliability in the 2006 model?
September 14, 2013
Followup from the Pelican Staff: M97 engines have similar issues, the IMS is one of them. The later engines have not been in circulation as long, so the bearing can seem ore reliable. Have a pre-purchase inspection performed on the vehicle, this is a good way to figure out which to buy. - Nick at Pelican Parts
Comments: I recently took my 2003 Boxster into the dealer for an oil change. The team at Beverly Hills Porsche performed a thorough inspection and discovered that there was "seepage" coming from the area where the transmission connects to the engine.

Followup from the Pelican Staff: You will have to check with your local Porsche dealer to see if the failure is covered. Call then and have them check your VIN and explain the issue to them. - Nick at Pelican Parts
Comments: I have a 98' boxster that I recently purchased. The guy I bought it from owned it for about a year and spent that time working on it as a project, not really driving it. He removed the engine to clean it car is pristine and he did some upgrades. Stainless steel headers with cat back hi performance stainless low flow exhaust and a cold air intake. Currently, the check engine light is on and I have codes for all the oxygen sensors and Idle air control valve. Is it likely all the Oxygen sensors went at the same time? As far as the idle, it seems like it is working fine.. no fluctuation at all. What could cause all these codes to be thrown if its not actually the sensors? I should add that the check engine light was on when I purchased the car the other day. I purchased as is.
September 13, 2013
Followup from the Pelican Staff: How many oxygen sensors have codes? I would check operation of each sensor. If they cannot respond to changes in the exhaust gas content then they are faulty. There may be an air leak causing the idle valve fault. If the o2s are switching, this could also be part of the problem with them, - Nick at Pelican Parts

Comments: I am looking at a 2000 boxster with 90,000 mi was service well. Last service was 2.5 yrs ago at 80,000 not driven much in the last 9 mo. I am also considering a 1999 with 103,000 mi owner says they had it service but no records. Both are visually excellent. The 1999 is $2,000 less. Which one would you recommend ?
September 8, 2013
Followup from the Pelican Staff: I would lean towards the 2000. However, I suggest having a pre-purchase inspection perfromed on both vehicles. A mechanic can help to identify any problems you might not be able to see. - Nick at Pelican Parts
Comments: Hi I have a 98 boxster, i had an accident about a year ago. The front right was hit, and the radiator and wishbone for the wheel were replaced. The A/C doesn't work nor the horn. Now the main issue is that it idle extremely rough. And will not accelerate at all. When left in neutral while parked, it will not rev past 3,000 rpm and sound like there is a bickfire. The car is at the shop and the throttle body was replaced, the issue remains. The fuel was checked, pump is working fine. Plz help me with suggestions.
September 7, 2013
Followup from the Pelican Staff: I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. It may indicate which cylinder is giving you an issue. If the engine is backfiring, it could be a mechanical timing issue. - Nick at Pelican Parts

Comments: I have a 2006 Boxster with a little over 80,000 miles. I have had zero problems with it since I bought it three years ago. I have put about 45,000 miles on it with normal driving. I have had regular service with a shop I trust tune ups oil changes brakes etc but I just had the spark plugs and the air filter changed this week and the very next morning, driving down the freeway at normal speed, the engine started billowing smoke and oil level dropped. I stopped and had the car towed back to service shop and was told that thee was oil in the spark plug hole which had led to engine failure. The question I have is what could have happened? Is it just a coincidence that I just had the car serviced the day before? Any advice or feedback is appreciated.

Followup from the Pelican Staff: Your Air oil separator may have failed. have the shop look into this. Is can fill the intake with oil when it fails. - Nick at Pelican Parts
Comments: I am thinking about buying a 99 996. The car has 100,000 miles on it and looks in good shape. Runs wellwith no loss of power or hesitation and has new clutch. When I inspected the coolant expansion tank the back end of the cap had a thick tanish substance on it and the coolant looked murky and discolored not red or green. Didn't look muddy brown either. Dipstick was normal. Inside of oil cap hap slight witish discoloration with slight amount of water but engine was warm to the touch. My concern is intermix problem what are your thoughts. No white or black exaust.
August 29, 2013
Followup from the Pelican Staff: The coolant tanks tend to look like that. If you suspect intermix, I would have the cooling system tested, don't take a chance, these engines are expensive. have a pre-purchase inspection performed by a Porsche work shop, you won't regret it. - Nick at Pelican Parts
Comments: I would like to nominate valve springs to this list of engine problems. I had one break. I have a 2000 Boxster S with about 110K miles. I saw some chatter about them online, they may be the up-and-coming problem. Luckily it didn't do much damage, the valve stayed in place. The problem was the 30 hours of work to change it. I am putting in the Pelican IMS bearing while doing all this work. For the records, the old double bearing wasn't falling apart, but it also wasn't perfectly smooth.
August 27, 2013
Followup from the Pelican Staff: I haven't heard too many valve springs breaking, but we appreciate the new info. Replacing an IMS when it is not faulty is the best time to do it, before it fails and causes engine damage. - Nick at Pelican Parts

Comments: i have a 1999 boxter 2.5 and love it. just recently i had the water gauge goes high as 200 degrees so i stop driving it and immediately took it to a shop. No water leaks but the water was low in tank. They replaced the thermastat and cap on tank and vaccuumed the line. It always ran at 180 degree and now is 190 and light is flashing. The fan is running strong. What could be the problem for i do not want it running at 190. Help
August 16, 2013
Followup from the Pelican Staff: You could have a failing water pump or debris restricting flow. I would inspect the thermostat and check the cooling system for exhaust gases, just to be sure. - Nick at Pelican Parts
Comments: Today I was driving home when my ABS light flashed on then off again. When I reached home I turned the engine off. Then I turns the key to see if the abs light came on but it never. But then the dash said faulty airbag. So I turned the car off again and then turned the key again and all the dash lights flashed. Then the alarm.went off. It was like the car was possessed! I got out unlocked and locked the car and have not touched it since. I did notice the car was revving slightly higher and the temp was slightly higher than normal.

July 25, 2013
Followup from the Pelican Staff: You do not want to look for HC when testing a cooling system for a head gasket issue, you want to check for Co2.
I cannot offer any advice as to what may have happened as I was not involved in the repair. If you are confident in your repair precedure, just stand by it and hopefully it will work out. - Nick at Pelican Parts
Comments: Hi, I have built a 3.2 boxster 96/21 for racing in the UK.
The engine is standard except for a deep sump and accumulator. First time out after 5 laps it started to rattle and the oil light flickered, my first thoughst were knackered engine crank bearings. Having run the car again at home all sounds well with no rattles but the oil light still flickers at low revs. The rattle didn't sound heavy enough to be big end or main bearings but having taken the sump off there is light residue of something very wrong, but the small particals are bright gold or brass not what I would expect from white metal bearings. Before I start on my first Porsche engine strip and rebuild any ideas on what the problem may be.
Very usfull articals by the way
July 17, 2013
Followup from the Pelican Staff: Sounds like yopur oil pressure is low, I would check it with a gauge.
I have seen metal debris in oil pans and oil filters look gold colored but be from bearings and other parts. Check the debris with a magnet. It could be from your IMS bearing or other engine bearings. I would cut the oil filter and inspect it for debris also.
if there is engine noise, the damage has been done. Hopefully you caught it early enough to minimize damage. - Nick at Pelican Parts

Comments: I hope you can provide some guidance? I have available to purchase an early 05 Boxster base 5 speed manual with 14,700 miles and clean title. The owner purchased it in May 05 and did the full dealer 20,000 mile service at 6400 miles in 2008 and did an oil change in Feb 2012 at approx. 12,650. So the original owner did two oil changes in 8 years and did a total of 14,700 miles. Should I walk away or does the low mileage mitigate the lack of oil changes? If purchased,price is $21500 should I do the IMS upgrade immediately? Your input is greatly appreciated.

Am considering a Auto transmission 1999-2001 Boxster or Boxster S in the $7000-10000 range. I am comfortable working on cars Miata, Audi A6, VW Passat, Subaru WRX, Mini Cooper from exhaust swaps, sway bars, brakes, radiators, water pumps, and timing belts.
What should I look for inside and outside when inspecting a used Boxster in this range? I will consider a mechanic inspection, as well, but I'd like to know what to look for during and initial drive and inspection.
Let's also assume the seller only has a Carfax report and minimal service records.
July 5, 2013
Followup from the Pelican Staff: Check our tech article list for Boxtser vehicles, this will give you an idea of the common issues. The indicator is a well maintained vehicle. A vehicle someone has cared about and cared for will likely need less work if any. My suggestion is to pay for a vehicle PPI. - Nick at Pelican Parts
Comments: Hi I have a 2001 boxster s shes stood for some times, an reasantly the brakes have gone rock hard? It stops but you've really got to push? The servo is acting ok , pump the peadel an then start peadle sinks slightly so in my mind that's how it should be! Any thorts would be fantastic!
June 30, 2013
Followup from the Pelican Staff: If the pedal is rock hard, the brake booster could be faulty, or you could have insufficient vacuum to the booster. - Nick at Pelican Parts
Comments: I recently bought a 2005 Boxster with 21K miles on it. I noticed that at highway speeds there is a mechanical whine that goes away when I depress the clutch and let the car coast at the same speed. The whine is at a constant pitch even when the speed or RPM changes, just the volume seems to increase when the car warms up more. At low speed I cannot hear it. Any ideas if this could be a bearing starting to fail?
June 28, 2013
Followup from the Pelican Staff: This noise could be a bearing. The way you describe it going away when you press the clutch leads me to believe it is a clutch bearing. It sounds to me like the throwout bearing is the culprit. The pilot bearing is not spinning when the clutch is engaged, (clutch pedal up) so it is unlikely the pilot bearing is making the noise. - Nick at Pelican Parts
Comments: I own a 996 tiptronic 1998 with the 3.4 engine with 85.000 miles. I hear a tapping noise when the engine is hot and it goes away when reving the car even slightly or engaging the tiptronic in "R" or "D". Sometimes the noise is heard on and off at random. The oil pressure remains the same. The Porsche dealer is unable to give a solution so I come up with one. When I engage a gear in the tiptronic it alters the load or weight/mass of the crankshaft and increases its demping effect. The car is 15 years old and as the chains wear and the sprockets wear eventually there could be enough slack to allow the snatch to sound like a tapping noise. Am I right and could this noise merely a snatch noise slowly creeping up on older engines and harmless? The noise is being heard for years while the car always drives perfectly and is in a well maintained condition.
June 24, 2013
Followup from the Pelican Staff: I would think not. If the chains wore or stretched slightly, the chain tensioners would pick up the slack. Therefore negating the noise. If you have constant noise, you may have a worn timing chain guide or other component. I would suggest putting an oil pressure gauge on the engine and confirming it is good. - Nick at Pelican Parts
Comments: I have had my 06 Cayman for the past five years and have enjoyed it very much. 34,000 miles, properly maintained and driven. No track time. It is now burning a quart of oil ever 1000 miles. Only smoke visible is on startup. I was thinking th aos might be failing, but it idles fine and has suction where oil is added. Hoping I don"t have a a scratched cylinder. I would appreciate your thoughts. Dealer said oil consumption is within guidelines. Thanks
June 13, 2013
Followup from the Pelican Staff: Leaking valve stem seals usually lead to smoke on start up but goes away when warming up. A little oil usage is normal with these engines. I hope that helps - Nick at Pelican Parts
Comments: Hi - I would really appreciate your help. I have a 2003 C4S with 80,000 miles, and it is great. However one problem that has recently started involves getting past 4000 RPM in any gear. Once you hit this 4000 RPM, there was a judder, like a mifuel, and the revs became jumpy and indeed stopped accelerating. Coils changed, same thing happens. Fault codes said crankshaft sensor and cylinder 2 electrical short to ground. Sensors replaced, plugs replaced - all running great - for 1 month. Now starting to happen again; yesterday it "hesitated" at around 4000 RPM; no reaction, then later on same again then CEL is illuminated and power is lost. Turn on / off and drives fine but with CEL still on. Dealer said no error codes logged. Suggestions of variocam actuators? any other ideas? Thanks Jason
June 7, 2013
Followup from the Pelican Staff: if the check engine light is On, there will be fault codes stored.
I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
The electrical circuit codes you had in the past may point you to the root of the problem. The wiring harness may be damaged or shorted.- Nick at Pelican Parts
I'd had 08' Cayman S from new and 65K KM with it..Last year my engine had damaged due to main bearing fault.after repaired them damaged again last week.
I'd find out water leak at below water pump near black case..cause fault from here??
My question is after repaired engine and started had P0304,P0305,P0302 misfire..rough idle I mention.
Check already for coils,spark plugs,wire plugs had 12V,
Also Unburned fuel can be found after start.
Need help for result my engine fault plz.
June 5, 2013
Followup from the Pelican Staff: The coolant leak could be a hose or water pump. I would pressure test the cooling system to locate the source of the leak.
The misfire codes need to be addressed also. Check spark, injector pulse and fuel delivery at cylinders with codes. If all is OK, check cylinder compression.

May 12, 2013
Followup from the Pelican Staff: If the problem is only present at low RPM, it could be a vacuum leak or slight engine misfire.
I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
If there are no fault codes, check each cylinder for spark, fuel and compression. - Nick at Pelican Parts
Comments: I've had a 1997 Boxster for 4 years now and would like to dispell some of the "myths" surrounding Porsches. The bottom line to Porsche longevity is strict maintenance. Also 90% of the time, as with any car, catastrophic failure will present warning signs. Porsches are not for the mechanically incompetent. Need proof? Look where the engine is. All that being said, there is no car I've driven that remotely compared to driving a Porsche.

Hoping you can provide guidance. I purchased a 2004 Boxster S new and currently have 24K on it. Love it and plan on keeping it despite the lack of power! Last year prior to storage, I was beating her up and missed a down shift. I no longer have second grinds. First works well but is no longer fluid to shift into. 3,4,5,6 are still smooth like nothing happened. It is a 6 speed manual. I have limited knowledge of transmissions and would not know if I'm being taken to the cleaners. Can you give me an idea of what components should be looked at before a complete rebuild is needed? Appreciate your forum and the help.
April 23, 2013
Followup from the Pelican Staff: It might be the detent in the transmission that has failed - those have a weakness in that area. You can strengthen it, but typically not after it's been damaged.

March 27, 2013
Followup from the Pelican Staff: Is the car using oil? Check your oil level and see if it is going down over time. It is possible to consume engine oil from a few places. For example, the oil separator, valve stem seals or dirty piston rings. - Nick at Pelican Parts
Comments: I am considering buying a 2000 2.7 L, 5 speed Boxter with 20,000 miles. CARFAX is all OK with gradual mileage progression, but car has had 3 owners, and service records are only available from current owner, back to 2009. Only recent problem is rear seal leak which has been corrected. I can have car checked by Porsche mechanic. In light of engine problems you describe, do you think this is a bad investment? If I buy it should I have IMS upgrade done? Thanks Steve
March 4, 2013
Followup from the Pelican Staff: We recommend the IMS upgrade for your engine. When having the car checked it would be a good idea to check the oil filter for any signs of IMS bearing failure.

Comments: My boxter 2000s has sat for two months. I briefly started it last week 10 second max with the normal white smoke and noise. I started the car this afternoon again a very loud knocking sound on the right side of the engine has made me very concerned. Even after the car ran idel to operating temp the load knocking noise from the right side of the motor did not go away. What is the ptoblem
March 2, 2013
Followup from the Pelican Staff: If you had no noises in your engine prior to storing it for a few mouths I suspect the lifters have bleed down. You did not state if you drive your car to get the engine temp up or left it idle. Try starting it and running the PRM to around 2500 for a few minuetes or until normal engine temp is acheived. Hopefully the noise will go away. If the noise gains intensity a further diagnosis will be needed. - Denny at Pelican Parts
Comments: I just replaced the AOS on my 37K miles 03 Boxster S because it had the tell-tale symptoms described in this forum. Anyway, the high-pitched screeching sound is gone confirmed by the tear in the diaphragm. However, the car won't stop smoking like a choo choo train. Also, the CEL is on. Any ideas? Thanks
February 20, 2013
Followup from the Pelican Staff: The smoking may be cause by residual oil in the exhaust from the AOS failure. It can sometimes take a good drive and heat to burn the oil out. The only way to tell is drive it and see if the smoke disipates. The check engine light is most probably caused by oil contamination of the oxygen sensors.

February 18, 2013
Followup from the Pelican Staff: All of those codes relate to Oxygen sensor signals. I suspect you have an intake leak or the air mass meter has failed causing incorrect fuel mixture. That is a very common problem.

January 25, 2013
Followup from the Pelican Staff: I am not completely sure what you mean by your question here. I'll have to make some guesses and some assumptions. When you say there is high pressure in the oil, I think you might mean that there is a lot of vacuum pressure on the oil. This is a sign that the air/oil separator is failing. The smoke you are seeing is also a symptom of this problem. I would check out our tech article on the replacement of the air/oil separator and I would replace this unit ASAP. - Wayne at Pelican Parts

It only had 17k miles when I bought it, has another year and a half on the certified warranty, and Porsche told me I didn't need to bring it in for service again until 27k. Right now I'm at 24k and change. Why do they tell people to wait 10k miles between oil changes if 5k is the real requirement? I don't understand what they get out of the deal. Anyway, it runs like a champ but I guess I'll start changing the oil more often. Love the car but I'm worried. :/
January 21, 2013
Followup from the Pelican Staff: . Although I'm not 100% certain I think the reason why Porsche recommends extended oil changes is because the car companies have been pressured by the environmental organizations to reduce the amount of used oil that needs to be recycled each year. In addition to extended oil changes the cars generally run a little bit hotter in order to help evaporate water from the oil. This additional heat does not help the engine either. I still firmly recommend that you replace your oil every 3000 miles, or 5000 at the very latest. Doing this seems to reduce the chances that the intermediate shaft bearing will fail. Also, it would seem that cars that are not driven very hard or very often seem to be most susceptible to the problem. So I would just change my oil often drive the car hard. - Wayne at Pelican Parts
Comments: Dear Sir
I'd like to know if is necessary to fall apart the complete engine boxster S to replace the head gaskets ?
January 16, 2013
Followup from the Pelican Staff: Your question is a little bit confusing, but in ourselves that you mean, "do I need to remove the engine from the car in order to replace the head gasket?" The answer is yes. You can replace the cam cover gasket with the engine in the car but in order to replace the head gaskets, yes, you need to remove the engine from the car. - Wayne at Pelican Parts

Followup from the Pelican Staff: Did you accidentally reverse the battery terminals when reconnecting? Did you remove the battery when you charged it?
I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. - Nick at Pelican Parts
Comments: currently my wife has a 2001 boxster s as the weather got colder haven't been driving as much. Now shifting between 1 2 3 the engine is over revving before engaging and the engine with a high pitch whine.
January 12, 2013
Followup from the Pelican Staff: Unfortunately, you have an provided me enough information to diagnose this problem. It could be a clutch issue, where the clutch is slipping, if you have a manual transmission. It could be an issue with your automatic transmission, and the fluid inside, if it's slipping before engaging. Off the top of my head, it doesn't seem like it would be an engine issue, the more of a transmission issue. I'm going to copy this question to the forum, and if you can add some more additional information there, perhaps we can help further. - Wayne at Pelican Parts
Presently own '99 Miata with 68k; no issues. Found a '99 boxter with 29k.
It's pretty, seems to drive ok, price not too bad.
I'm tempted but frankly scared of buying car with hidden engine and
reputation for lots of problems.
Maybe I should stick with what I know?
January 11, 2013
Followup from the Pelican Staff: I wouldn't necessarily say that Boxster engines are more or less reliable than Miata engines. However, they are significantly more expensive to replace with something goes wrong with them. If you follow the standard upgrades for the Boxster engine, like replacing the intermediate shaft bearing, and keeping your oil change intervals to about 3000 miles or so, then you should be okay. The good news is that the Boxster's are getting cheaper and cheaper every day, and they are a really huge bang for the buck these days, even when you consider the risk of having engine problems occur in the future. Plus they are really fun cars to drive. - Wayne at Pelican Parts

Comments: My 2009 2.9 987 with 51,000 miles gives me check oil level warning after about 1 hour running. When checked oil level is at maximum. Is this software malfunction or something more serious?
January 3, 2013
Followup from the Pelican Staff: This is an interesting problem. I could be caused by one of many factors. The first thing that comes to mind is to check the oil level sensor, although if the sensor is defective, I would think it would not be reading correctly when the car was cold. On the other hand, there may be some type of foaming that is occurring inside the engine after it's been running for a while. Your car does not have a dipstick, so it's difficult to look at the oil in the side of the engine to determine. Another thought comes to mind as well. I remember hearing about an air cooled 911 dry sump engine that ran out of oil when it was being driven at high RPMs for an extended period of time. The problem was that the engine was having its oil sucked out of the sump at a rate that was fast enough to replenish its use throughout the engine., But I do know that it was caused by an oil pump that could not keep up. I'm not sure how this relates to your engine, but it certainly is food for thought. - Wayne at Pelican Parts

Comments: I have a 2003 Boxster Base with 35k on it. Just this Spring I had a IMS replacement with the LN part done at 33k as a precaution while they did a oil/water interchanger repair. Just this week, the engine appears to have suffered an engine failure. Sounds like IMS. Unfortunately the dealer who did the work is 1500 miles away now, as we moved. Could it be something else, though it sounded like metallic marbles upon failure. Is it possible to sell the car in its present condition? Obviously very unhappy.
October 22, 2012
Followup from the Pelican Staff: It's pretty difficult to install the LN Engineering kit incorrectly and then run the motor for several thousand miles. So, I would hesitate to blame the IMS bearing in this case. As you can see in this article here, there are plenty of different ways that these engines can self-destruct. I had one in my 2000 Boxster that blew up - the IMS bearing was fine (see the article on engine teardowns). I could never definitively figure out what caused the engine to fail - there was too much destruction. The bad news is that you probably need a new engine. You can sell the car in this condition, but I doubt you would find a buyer willing to pay more than $5K or so for it, unfortunately. I will copy this question to the forums, and the folks there will probably have some additional input for you. - Wayne at Pelican Parts

Comments: A few thoughts: "Using the expertise gained from years of designing and building engines, Porsche developed what is known as the M96 engine for the introduction of the Boxster in 1996." That statement is incorrect. The fact is that the company only has real experience in building engines for racing cars. Apart from the all alloy 944/968 engines the rest of the pruduction types are of VW or Audi basic design. The company does not have the depth of staff to support the expansion it created after 1995. They are good marketeers and so so designers, as far as engineering integrity goes..well ..read above. Don't be fooled and shop around.

My mechanic thinks moving metal parts probably caused the crack. I changed my oil much more frequently than the every 15,000 miles recommended by Porsche. I also did the 30,000 and 60,000 miles tune-ups. Aren't these engines supposed to at at least 100,000, if not 200,000 miles? Any guidance would be highly appreciated.

It is obviously an IMS failure. I dont know whether the metal parts of IMS destroyed the engine or not. I was 25mph when it happened
However either case is not good. Best chances, if they repair the engine, it will cost 10k$ and no guarantee- maybe they cannot fix it. Worst case scenario is a new engine which is more than 20k$.

Followup from the Pelican Staff: How did they explain to you that full-synthetic oil offers worse protection? Synthetic oil can withstand higher temperatures and therefore offer similar lubrication qualities hot or cold. If you are going to drive like you have a high performance car you are going to have to do more maintenance. - Nick at Pelican Parts
Comments: I have a 2001 Boxster S with the 3.2L motor. I was recently driving at moderate speed. When I looked at the gauges, the temp needle was about maxed and the motor died. The head gasket failed. Do I assume it is dead and buried? What is my best path from here? Replace the motor? Too far gone for rebuild?

Followup from the Pelican Staff: Hmm, that is unfortunate. I would say yes, your engine is pretty much shot and you either need a new one, or you can rebuild the existing one. I'm not sure which method is cheapest these days, it all depends upon if you can find a good used 3.2 S engine. - Wayne at Pelican Parts
Comments: I have a Boxster 1997 2.5 ,I recently purchased vehicle but have been strugling to get reverse gear now i cannot get reverse all other gears are fine
Comments: According to this website, Boxster engines are an absolute nightmare. I have a 2001 Boxster and touch wood never had a problem in a year. Reading the suff on here though doesn't fill me with confidence and it can ruin the driving experience worrying the engine is about to self-destruct at any moment. Wish I'd never read this crap now.

Followup from the Pelican Staff: Porsche engines throughout the years have always had problems and issues - the Boxster engine / drivetrain is nothing new. There have been a bunch of failure of the Intermediate Shaft Bearin (IMS Bearing) over the years, but that is now repairable with aftermarket kits. I think the important thing to remember is to change your oil every 3,000 miles or so. - Wayne at Pelican Parts
Comments: Waynem I have a used 1998 Boxster that I recently purchased.
I have had it tuned up and services by a reliable independent mechanic in Jacksonville. Fl. I spent approximately $2700 on the turn up and front break over hall. I have subsequently developed a loud chirp when the engine gets warmed up. I have been told that I need to replace the water pump and possibly the AC compressor. Can you shed in light on what might cause my car to chirp. By the way the temp gauge has never indicated overheating and stays in the 160 to 180 range. Before I spend any additional money on repairs, I need a second opinion. Thanks

Followup from the Pelican Staff: A chirp as you describe it typically means a squeaky bearing somewhere along where the belt runs. That is why your mechanic was talking about the A/C compressor or the water pump. In reality, it may just be an idler pulley, you can see the procedure for replacing them in my other article here: http://www.pelicanparts.com/techarticles/Boxster_Tech/17-ENGINE-Idler_Pullies/17-ENGINE-Idler_Pullies.htm You might have to do some trial and error to figure out where the sound is coming from - I typically like to spray WD-40 on each bearing to try to figure out where the sound is coming from. Others might have suggestions - I'll copy this question to the forums. - Wayne at Pelican Parts
Comments: hi i have a 1999 boxster, i have had it a few months now and it has run great. up to last week. now whenever i accelerate and my rpm gauge reaches 4,000 rpm the engine stalls and drops down to around 2,500 rpm. i had my car smogged a few weeks ago and found that the O2 censor is not working. could this be causing my computer to be on limit mode and not working properly??
Comments: Hi, I have a 2003 996, when the car reaches 200F stalls and doesn't start and I see the rpm idles up and down even though the car is not running. But when it's cold it runs very smooth and fine. I replaced the crank position sensor still the same and just put a new dme and still the same way. Any idea's of what would be the problem?
Comments: Hello I would first like to commend the very it at all times is a possibility of my Porsche Boxster 2.5 bj 99 a couple of photos and information on bekommen.Hier in Germany it is not even possible to have some information from the workshop to complete all bekommen.Die fear of losing their job pisses me off all here, all top secret ... do not even get the torque of my clutch I want to install as soon as possible ... they can help me and give me a list of times the torque of the coupling and valve cover it schicken.wäre not even possible to translate the whole thing in German and to bring in the internet .... love .... many greetings from Hessen Bebra Ricco

Comments: I have a 2000 2.7L Boxster that I replaced the head gaskets on trying to fix an oil in coolant problem. This didn't fix it and I'd like to know if the 2.7L engine can develop the same cylinder liner cracks as the 2.5 & 3.4L engines. What is the cost to machine the case and replace the cylinders with Nikasil cylinders?
March 17, 2011
Followup from the Pelican Staff: Yes, these engines too can experience the cylinder liner cracking that you mention. LN Engineering does the replacement of the liners with new ones - I'm not sure what they charge for the procedure, but as you might imagine, it's not terribly inexpensive. - Wayne at Pelican Parts

Porsche is offering a 50% offer at a $13K engine replacement for my Boxster with 32K mi, bought new. Do I get the new bearing?
September 21, 2010
Followup from the Pelican Staff: The new factory rebuilt engines come with the latest-style bearing, so I would guess yes. However, I'm not 100% sure that this new bearing completely solves the problem. Time will tell! - Wayne at Pelican Parts
Comments: It seems that the M96 engine is the problem. With regards to the major IMS failures; what model years of the Boxster have been modified to avoid catostophic engine failure.
June 10, 2010
Followup from the Pelican Staff: With respect to the M96 and M97 engines - they all seem to have failures all over the place. No one has quite figured out what the issues are and exactly what causes the bearing to fail. You can have a 31,000 mile car with a failure, and a 131,000 mile car with no failure. Frequent oil changes seem to help. Around 2006, Porsche went to the larger non-replaceable bearing which is supposedly better, but there still have been reports of this bearing failing too. - Wayne at Pelican Parts
