I had and possible still have a rear main leak. Got motor back from engine builder today, and when i asked him how he was sure it was fixed this time he said he pressurized the crank case. is this method good enough to be sure or should i go some where else and pay for an expensive engine dyno. tired of pulling car apart.

 

Did he replace it?

 

What block? One-piece seal or two-piece?

Might want to add a "signature" with info about your car, engine, etc.

 

97 ws6 now has 2pc rear main with adapter
