I just put in my new motor and I keep getting oil leaks from the rear of the engine, I have just taken the tranny out and replaced the rear seals, drove it around and it's still leaking! Any suggestions? I used all the correct tools for alligning the seals. I have no ideal what to do next!

 

If it's not perfect or there is an informaty in the gasket it will leak. Those things can be tricky, the rearmains are very sensitive when being installed. I would do it again and be real careful when seating it. Make sure to lube it up a little so you don't put it in dry. .02

 

Is it leaking from the rear crank seal or the oil pan where it meets the rear cover? BTW, the helms recomends not oiling the rear seal where it meets the crank shaft, for what ever that's worth!

I installed the rear main perfect and followed the GM service guide.

I think its the pan gasket! I going to get rid of the oil pan gasket and use a RTV called "Honda Bond"
