I have replaced my rear main seal like 3 times in one year. Just recently replaced it like a month ago and it has slow ass leak. Not alot of fluid at all, just enough to notice a little wet spot on the floor when I back out. anyone have any suggestions on how the stop the leak for good?
thanks [ July 08, 2005, 12:29 PM: Message edited by: 1992gtdrop ]

99% of the time it is not the seal, it's the crankshaft surface. Install a seal-saver next time, you won't have this problem.

yeah I changed my rear main last year, driven the car maybe 3000 miles since then and the starter side of the bellhousing is covered in oil
point us in the direction of the seal saver! I needed to drop my tranny anyways to replace a cracked throw out bearing retainer

The sleeve is Fel -Pro Part #16250 and you will need the instalation tool which is #16300.

It's a really inexpensive sleeve that slips over the end of the crank. It is good insurance.

I would look to elsewhere as well. A rear main doesn't just "blow out" after xxx-number of miles. Like CDT said, check your PCV.

the rear main seal is in the rear of the engine so you'd have to pull the tranny

Yes, this requires a tranny/flywheel pull.
