Timing chain gaskets
Hi,
Anyone know if it possible to replace the timing chain cover gaskets with the engine still in the car (primarily the one behind the distributor). I know the standard reply is to remove the engine but I'm sure I've read of this being done with the engine still in the car. The guy got stuck with a nut behind the A/C mount but as this is the opposite one to the one I would like to replace I got thinking? I assume he must have removed or repositioned the tinplate at the rear somehow to pull the covers off.

Richard;
The drivers side can be done. It would be easier to drop the engine down 2-3" to clear things. Yes, you need to remove the rear tin, but prior to that the mufflers need to be removed, along with the heat shielding.

Richard, I'll second that...it can be done, but as Kevin mentioned, you'll have to get the exhaust and part of the engine insulation/sheet metal out of the way.
The big deal with the right side is what you mentioned - the AC mount. The crank pulley has to be removed to get the AC mount off because of some silly tabs that are molded into the aluminum mount. I have seen a couple people in my area grind the tabs off as to facilitate removal of the mount if needed in the future - without having to remove the crankshaft pulley.
If you think removing the crankshaft pulley is a pain...wait till you have to put it back on!! ...and ALIGN the damned thing! I have no idea why Porsche did this on the 3.6??
Cruel and unusual punishment I guess! <img src="graemlins/cussing.gif" border="0" alt="[grrrrrrr]" />

Hi,
So am I right in interpreting that the LH side is DIY, but not recommended for the RH side? I have small leaks coming from both sides (just a few drops now and then), and was thinking about taking a crack at replacing both gaskets. Figures that the worst side is the RH side. Not so sure after reading this. Other than the items mentioned in the other posts, what would need to be removed? I figured the exhaust, A/C compressor, belts etc. Anything else? Is this a job better left to my mechanic?
Thanks,
Hans

Depends on how adventurous you are Hans. 
Yes, you would have to remove the items mentioned for the RH side.
I found that after I replaced the two gaskets, I still had considerable leakage coming from that area and am regretful that I didn't go in and replace the chain housing to cam housing "O"-ring and gasket...not THAT'S NOT for the faint of heart!

Jeff:
My 91 C2 is also leaking quite a bit from that area. How many hours does Porsche account for taling the engine out and replacing those seals, gaskets. My car currently has 82,000 miles and still runs fine. Should I address anything else at that point?
Thanks,
Chris
