Hey Guys -

Just about ready to be done with my AODE to T5 swap, but figured I'd replace the rear main seal prior to installing everything. I've heard on here and other places that these are infamous for leaking again after replacement -

Does anyone have a trick to test the seal for leaks before bolting the flywheel/trans/ etc back up to the car? Want to avoid having to pull everything back out should a bad leak pop up.

Thanks!

No real trick but carefully inspect the surface of the crank where the seal rides. If you can catch a nail on the groove, the new seal is going to leak. You'll want to put a sleeve on there if that's the case. If not, it'll be fine provided it's installed properly.
