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? [Confused]

thanks [patriot]

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. [Smile]

what's a seal saver?
my car is down possibly due to a defective rearmain seal.
If i go through this again i just want to do the job once.

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 [Mad]

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. [Frown]
