Dani,

I should have checked my records before responding. You only replaced the
disc (New Valeo) and an axle seal at the time. Had you spoken directly to me
at that time about an oil leak I would have suggested that the leak was
likely coming from the input shaft seal and would have advised you to split
the cases, sleeve the contact area, and change all of the seals and gaskets.
Unfortunately that is probably what you will have to do to prevent another
recurrence of this problem. I do think I suggested replacing the complete
clutch but don't recall a discussion about oil leakage. We recently did this
exact repair, about the same time you did yours, to another daily driver and
it solved the exact same problem. This time however you will probably need
to replace the complete clutch and grind/machine the flywheel if you want it
to last and be smooth. While you're in there I'd also suggest double pinning
the second gear shift fork for added longevity. The loads on your clutch and
driveline are a little different in both second (Is that a rolling shift or
from a dead stop?) and especially reverse so that does not eliminate the
likelihood of an oil fouled disc. The engine rear main seal is an unlikely
suspect as the disc is shielded from the seal by the flywheel and I've never
seen it foul the clutch. I would replace it while you're there anyway or
Murphy's Law will kick in and you know what your next problem will be! Sorry
for the gloomy diagnosis but I am pretty confident it's the right one.

Rob-new or reconditioned?-you tell me, I got the clutch disc from you
(along with other misc. transmission gaskets/parts) and I'm not quite
sure if it was new or reconditioned. I bought and installed a new disc
and pressure plate a little over a year ago. The disc would still be
in there but when my transmission leaked the oil all over the disc,
there was no point in replacing a new pressure plate so I just put in
the new disc from you (Rob). My questions is-why is this suddenly
happening? Why not last month, or the month before (I didn't JUST put
the clutch in and it's just suddenly happening after the work) why
isn't it happening in reverse or second gear and why is my pedal
height the same... These were all reasons I didn't think of the clutch
as a problem. Can a reconditioned clutch have such a short life? I'd
understand if I was racing around burning the clutch all the time
(even then it should last a long time) but that's hardly the case for
me-the hardest it's seens is now when I have to start in second
instead of first. My flywheel seems to be fine, not worn and had no
scoring so I didn't se a reason to get it cut. -----dani
