I don't know how yours behaves exactly but mine has a sort of two step when you clutch. You get the initial bite and then you think okay I'm starting to roll then you get this secondary jump when it bites in again. When I drive the 55 I just sort of ease into the clutch with a little bit of rpms. On the vette you have to pump it a little otherwise it'll just buck. I have no clue on the history of my clutch or what kind is in it. All I know is the pedal is amount the most on off clutches I've ever driven. The engagement is right there...

I'm visualizing it as the engine is spinning and the seep is being flung by the output shaft and Kind of misting in the bellhousing just causing a constant fine spray if you will. The stop and go is allowing that fine spray to sort of be like a misting coating, like spraying wd. I really doubt it's the case but anything is possible. Each time you clutch you get a little of it on it. Most ends up vaporized and leaves. Some stays. If I spray water on my rims and go for a quick drive it'll all pretty much fling off. If I spray tire shine and go for a quick drive I'll have runs and droplets. The viscosity and shear also play a role. Granted the tire is spinning at significantly less revolutions per minute than the flywheel is but the same theory applies as long as the mass balances and force balances check out.

I said it just to be that guy (anything is better than nothing sometimes.) I really don't believe this is what's happening. I'm sorry man. Didn't mean to mislead anyone. I've seen some weird things happen. So anything that comes to mind I end up saying. Usually I end up being the jerk too. Again, sorry...

You are not being a jerk in my mind. I just don't think you fully understand the interior workings and are just throwing some **** at the wall to see if some sticks. No problem, you more or less said so.
In any case, I think there is a better chance of my aunt growing a ******* and becoming my uncle than there is of a main seal weep contaminating a friction surface on the flywheel.

huh. Sounds like mine.

My original Ď85 (now my parts car) had the stiffest clutch Iíve ever felt-it bit and bit HARD. I think it must have been an upgraded racing clutch or something because the previous owner had been turning it into a drag car. It had other problems but the clutch/OD werenít one.

I'm starting a new thread to ask for help on dropping the transmission. I figured this thread has wandered enough that it's probably time to start a new one HERE.
