Cleaning the engine at first looks like a daunting task, but if you take your time and
have patience the benefits will last for years.
Lets assume you have an older
Porsche whose engine has never been touched beyond changing the oil and minor maintenance.
You look at all the grease and gunk and want to say "Forget it!" My 911E was
like that, the car had been raced, rallied and toured to the point I had over 300,000
miles on it. The engine was well maintained and clean by those standards. But not where I
thought a person could put their hands in there without coming out with a grease trophy.
So where do you start? With a good
engine wash. Take a can of engine cleaner (GUNK or some other comparable product) and go
down to the local "Do It Yourself" (DIY) car wash. Why the DIY, because;
A) The DIY tanks are set up for yucky engine junk and will not hurt the environment
B) Most of us do not have a high-pressure hose at home; youll need it.
C) The area around your car will be a mess afterwards
Here are the following things you will need to
take with you on your journey to the local DIY (do-it-yourselfer).
Tape, Baggies, toothbrush, plastic wrap,
rags, 2 plastic trash bags, towels, note pad, rubber bands, gloves and lots of quarters.
First thing to do is protect your
electrical components. Take a baggie and put it over the distributor, next use the rubber
band or tape to secure the baggie in place. Each model is unique on where the electrical
components are located, my 911E has electronics on the left side of the engine. I use the
plastic wrap to protect this area and tape to secure it. Look anywhere else the water may
cause you car-starting problems. If you have exposed carburetors, use the plastic wrap or
Baggies to protect them.
Next thing I do is disconnect the coil
wire, this way I wont pull a no-brainer of starting the car with plastic inside the
engine. You can guess why I started doing this J . Write
yourself a note to reconnect the coil wire and put it on the steering wheel. On the note
pad, write down the places you put the plastic and tape/rubber bands, it may seem
redundant but better safe than sorry. Now take the towels and place them over you fenders
and the deck lid. This will protect your paint from any debris and chemicals that may over
spray. I suggest you wear old clothes while cleaning your engine and use gloves to protect
your hands from the chemicals (latex is best).
Now you are ready to attack the built up
yucky gunk. Take your engine cleaner and spray it liberally in the areas of the engine
that have the most built up grease on them. Let the engine cleaner soak for a few minutes,
it will start eating away at the grease and dirt. Depending on how bad the build up is,
this can take anywhere from a few minutes to 20 minutes. You probably will not get it all
this first go around, so keep that in mind. While the engine cleaner is soaking, take the
toothbrush and gently work the engine cleaner on the worst spots, if you have a severe
build up, you may have to do this with a larger (not stiffer) brush. Once you have
determined the engine cleaner has stopped working, you are ready to steam clean.
Set the DIYs wand setting to
engine or steam clean (it may be slightly different depending on where you live). Take
care not to use the wand on the exterior paint of your car. The heat and pressure from the
wand was not meant for your paint. Now use the wand inside the engine compartment to steam
away the engine cleaner and grease. Be patient and get the wand onto the nooks and
crannies. Do not forget to get the sides of the engine compartments as well, dirt gets
kicked up into the engine from the fan and always seems to find its way on the
shelves of the engine.
While you are steaming the inside of the
engine, make sure you do not get water inside your plastic covers. Once you are satisfied
you have taken out as much dirt as possible (this go around), set the wand to rinse. The
rinse water usually has a softening agent and will rinse the chemicals out of the engine.
A word of warning, GUNK works great but
smells horrible. If you use GUNK, do not do this on the same day you are going to use the
car for a date or tour. It takes a couple days for the smell to go away. There are other
engine cleaners out there, I have tried the Citrus ones (they smell better) and GUNK. For
the nasty jobs I use the GUNK, for the easier ones (like the new car) I use the Citrus
When you finish rinsing the engine out
shut off the wand. Now take the rags you brought with you and wipe down the engine. Make
sure you use some pressure on the rags while wiping it down. The grease has softened
because for the heat of the water and will come off easily in your rag. When you are
finished with one rag (because it is too dirty or wet) put it in one of the plastic trash
bags. Keep wiping down until the engine is rather dry or you run out of rags. Next take
the towels off the deck lid and fenders. Wipe down the paint with the part of the towels
that did not get wet or exposed to the chemicals. When done with the towels, put these in
the other trash sack.
Now you are ready to get the engine
ready for starting. First take ALL the plastic, tape and rubber bands out of the engine.
Next reconnect the coil wire and make sure there are not any other foreign objects in the
engine, like towels, toothbrushes or gloves. Check your notepad to make sure you got all
your protective wrapping out.
You may want to put a few more quarters
in the machine and rinse down the area you have been working. Chances are some of your
greasy gunk might be on your shoes or get on someone elses, be considerate.
Sometimes our Porsche do not want to
start right away after a washing, make sure you give it plenty of time to start and take
care not to flood the engine. If you protected you electrical components from water, you
Porsche should not have any problems starting up.
If you should have a problem, push the
car into the sunshine and open the deck lid. Within a few minutes the components should
dry out and youll be on your way.
If your engine was really bad, you may
have to do the engine wash a couple times to get the worst junk out. Bare in mind, the
grease and gunk took years to get there and it will not give up its home easily.
Well talk about getting you engine
