rear main leak shouldn't affect clutch. oil would dribble down the block mostly, and some would on the back of the flywheel, it'd have to be a crazy amount of oil to fling around the bell housing and get to the front of the flywheel and clutch.

maybe if the gearbox input shaft was leaking you'd get more oil onto the clutch disc.

Reactivating this thread, I'm looking for a new clutch/pressure plate kit for daily driver use with my Gen 3 turbo. The engine is lightly upgraded for street use and runs up to 16psi maximum boost. Ideally I'd like to keep pedal forces close to stock.
Does anyone have recommendations or experience with something similar?

For mild mods and street driving, many people just use an Exedy Heavy Duty clutch.
