timing chain gasket
The gasket for the timing chain cover seem to have a rounded side and a flat side. I was thinking the rounded side should go towards the engine block and the flat side to the cover, but not that i think about it maybe the flat side would give you more contact area to seal with? what do guys that have done this do.. thanks

Rounded side towards engine, flat side towards cover.
The alloy yoke/aircon bracket (if fitted) around the crank pulley that hinders access to the chain covers can be removed with the crank pulley in situ. You need to double nut the four studs and extract these. The yoke can then be pulled out.
The studs will need bonding back in place, I think with Loctite 270, but check this before you refit. The PET lists a projected length for the four studs out of the case.

Instead of taking off the bolt for the crank pulley, I took off the hex bolts that hold the crank pulley in place. I ran a piece of wire through one of the holes and tied a knot so that I knew how to line it up later (someone's idea on this forum). When replacing, I filed down the ac bracket so that future removals are simple. Also I believe you have to use loctite blue instead of high strength to put back on the hex bolts.

Having just done the timing chain cover gaskets w/ the round side toward the engine, I got a bit concerned when I saw that the valve cover gaskets are opposite.
It would seem that one must be wrong. The valve covers and timing chain covers appear to be made of the same material.

There is actually a special tool that they use to pull off the pulley. You may be able to go to your local p-car shop and ask to use it. It is a bolt without the lower threads that pops the pulley off of its tapered fit onto the crank. There is also a special tool that you use to hold the small hex bolts to unscrew the main bolt. The other bolt like tool from porsche just gets screwed in where the actually bolt came out of. I also borrowed that tool as I don't even want to know what it costs. That was how I took the pulley off, perhaps there is another way.....
