The flywheel pictured below has 5k miles on it along with a new pressure plate, clutch disc, throw out bearing, etc.

Clutch slips under full immediate throttle from a healthy four.

What are all the "spots" an indication of?

Today I made some real progress. This morning, while examining my various clutch issues, I immediately noticed how slick my clutch disc actually is. Saturday when I removed it, my hands were so greasy it wasn't so noticeable, but with clean dry fingers it was quickly apparent that the disc is saturated. Dragging your thumb across the plate produced a gray/black thumb. Good for fingerprinting.

Also, the pressure plate surface was coated. The entire pressure plate had a film over it. My wife, who smells real good (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) confirmed that it was tranny fluid as opposed to engine oil.

I then removed the throw out bearing, and sure enough, there were signs of fluid seeping around the output shaft seal, and also around the pivot ball that had come slightly loose.

I took the disc to my porsche shop and ran it repeatedly thru their big hot/soapy parts washer, but it seems the disc is still leeching out oil. So it looks like I will be fitting a new disc.

While I was there, I also had them put in a new output seal in the tranny. If this sucker leaks, then I've got other problems (bent shaft/bearings out of spec?).

So tomorrow I should have everything back together.

I guess it will be a month or so before I'll know that the new seal is doing it's job, but hopefully my clutch slipping days are behind me.

Thanks to all for helping me to "grapple" with this mess. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
