Here's a close-up of the small intermediate shaft end bearing.  The hex-stud sticking out of the shaft is what drives the oil pump.

Here's another shot of the aluminum "bearing" where the intermediate shaft rides in the oil pump housing.

Here's a photo of the crankshaft pulley seal.

The main chain rail is held on with a small circlip that needs to be removed.

Using four of those super-huge studs as "handles", insert them into the crankshaft bearing housing.

Whoops, don't forget this bolt on the opposite side.  It attaches the crankshaft bearing housing to the case half.

Here's something we almost missed - you cannot take the crankshaft bearing housing off without taking off the pulley.  The boss that is used for the Top Dead Center (TDC) tool gets caught on the outer rim.

Lock the pulley into place using the TDC tool and then remove the large pulley nut.

With a friend nearby, pry up on the crankshaft bearing housing, and it should lift off of the engine with the intermediate shaft closely in tow.

Whoops, this fell out the opposite end when we started to lift the whole assembly.

Lifting the whole assembly.  It's heavier than you would think it should be.

This is really a two-man job.  I would not try to lift this yourself.  The angle is all wrong.  This photo really reminds me of when Indy and Sallah are lifting the cover of the ark in "Raiders".

The main chain will hold the intermediate shaft in place - don't worry about it falling apart.

Set the assembly down on your workbench so that you can complete the disassembly.

This six-cylinder Porsche engine is now a four-cylinder.

Here's the flywheel end and the intermediate shaft where the infamous intermediate shaft bearing is inserted.

Here's the camshaft solenoid advance mechanism.  Basically, as you actuate this solenoid, the two camshafts turn towards each other and the timing of the intake camshaft changes (the exhaust camshaft is attached to the chain that is driven by the intermediate shaft, so it's timing cannot change).
