Default Think my rear main seal is bad

Distributor isn't leaking and oil pan gasket is new and yet there's engine oil still dripping off the tranny.

Took it to my buddies shop to put on the rack and took out the cover that hides access to the rear of the engine/flex plate area an put the tranny is drive so it was spinning the tires an yet no oil can be seen dripping out from anywhere.

A bit confused as to why we don't see oil but I guess unless the engines under true load I've heard there are times you wont see it leak.

6.5 hours of labor on a 21 year old car that otherwise runs good.

Could be your tranny leaking. Or it could also be leaking out the back of the valve cover. Did you pull off the dizzy cap? The shaft seal likes to leak out of those. Could also be tranny fluid. Toss some UV dye in the oil and see where it shows up.

The inner and outer dissy seal was replaced and it's been double checked and no leakage.

It's def moter oil and and not auto tranny fluid.

I never thought I'd be in this situation with this car due to the tranny being replaced by the previous owner before I bought it.

Well, if you can unbolt the trans from the motor and try and crack them a little.

Are you saying the seal can be replaced without fully removing the tranny?

no you have to remove the tranny, plus you probably won't see it leak heavily just by looking as they are generally a slow drip type leak

Us flatraters like to use the "seal in a can". It's a secret so don't tell anyone. We charge about 8 hours for replacing a rear main seal when in fact what we do is open up a can of "seal in a can" and pour it on top of your engine. All leaks are fixed in a matter of minutes. GRAAAAAVVVVYYYY!!!!!!

Lol.

Just curious if there is a stop leak that really work. Depending on the severity of leaks (e.g., power steering, radiators, etc.) my own experience has never made me a believer in stop leaks that you pour in.

Agreed. The only "stop leak" that works is a new seal.
