    the clutch is out and i purchased a new rear main seal (along with the clutch, flywheel, mounts, lca bushings, ...) . however, there are no leaks and the only posts i read on rear main seals mention problems after replacement.

    the car only has 90k. should i just save the part for the next clutch change?

    At 90,000 miles, if it looks good, I wouldn't touch it...

    thanks for the advice. the benefit is probably not worth the risk at this point.

    i read a couple of posts that said that you should replace it while you were there and decided to buy the part and gasket material. i'll save them for another day.

    2 ways to look at it, and I agree with not replacing it.
    1. Don't replace it because it isn't leaking
    2. replace it because its old and could start leaking at any time.

    However, during the process of replacing it, you could screw it up and not know it. Its not fun to get to it.

    I replaced mine when I did my clutch because it was leaking. I'm glad I did but I had a scare when my CCV was leaking at the puck and dripped all the way down there.

    i have a leak at the tandem pump and am replacing that gasket. the rear seal looked good so i'll just let it be for now. new clutch comes tomorrow... can't wait.
