Installing Clutch - questions on condition of old

[Tidybuoy]

I'm installing a new clutch and I have a few questions regarding the condition of the old parts.

The clutch began to feel different as it had about 2" of pedal movement before enguaging. I believe I caused this condition because I had a nasty backfire during decal (exhaust leak) and to help reduce this, I feathered the clutch during downshifts. Now that I have it all apart, I just want some opinions on the pressure plate and flywheel - as well as the rear main seal.

Pic!#1 Very oily behind the flywheel. Does this mean the rear main seal was leaking? (I'm changing regardless).


Pic#2 Pressure Plate is very smooth but does have some brownish glazing. Can this be surfaced or should I not worry about it.


Pic#3 Flywheel is very smooth. I plan to have surfaced. Anything special I need to know for getting this surfaced?

Pic#4 Clutch Disk. Still looks good to me even though I will be replacing. Is it possible that I really only needed to adjust the clutch cable?

Visually, it all looks fine except the leak, it could be coming from the Triangle of Death, is the top of the engine dry, especially near the breather, thermostat and low oil sensor? If so, then yes it could be the main seal or the guide tube seal, which is much easier. Browning of the flywheel could be oil leak related, I am surprised you are not getting a clutch slip with that much oil.

If I may suggest, clean and lube the T/O bearing/Guide Tube ( check for leak at the seal inside the tube ) and make sure the pilot bearing is rolling smoothly.

The proper way to do this is to take measurements of the fly wheel and clutch disk.

Yes, it could have been just a clutch cable adjustment you needed.

How is the condition of the fork?

1) Maybe this was due to the "Triangle of Death". I just recently changed the gasket to the breather and replaced the low oil sensor. The sensor had oil coming out of the electrical plug and the top of the engine was very oily.

2) I am replacing the main seal and guide tube seal ..."while I'm in there".

3) I will measure the thickness of the flywheel. Does anyone know the spec or is this something the shop can look up. I am taking to a very reputable mechanic with lots of Porsche experience (just for the surfacing as I will do the rest myself).

4) I'm replacing the clutch disk and cable as part of this project as well as the throw out bearing and the roller bearing in the flywheel

5) The fork looks to be ok, which is a good thing since I'm about to go broke doing the project (includes new PMO injection and electromotive and rear suspension).

Thanks.

p.s. Thanks for the offer but I won't be home today....spending Sunday at work.

You have to replace the flywheel bolts if you don't they will break.

Thanks! I'm ordering small things today so I will add that to my list.
