Are you sure the leak is from the flywheel seal? Other possible leak
sources are the oil galley plug and a crack in the case, in front of
cylinder #3. If it is the flywheel seal, possible causes a loose/spun
main bearing or excessive crankcase pressure due to a piston/cylinder
problem.

Subject: Aircooled Rear main seal

I have a 1982 Westy and recently replaced the rear main seal and o-ring
on the flywheel.  Now it seems to be leaking again.  I used a silicone
seal instead of a normal one, Aircooled.net listed it as appropriate and
it looked and fit just as one would expect.  Does anyone have experience
with this type of rear main seal?
