Hi Ryan,

If it's the original seal, which it prolly is, they all leak. Some worse than others.


Can you replace it with a Fel Pro gasket. Make sure everything is very clean and fill the gaps with the "Right Stuff".

Dennis Kirban, the Turbo Buick guru says if your rear main doesn't leak, there's probably something wrong. It seems to me that cars that haven't been run often leak the most. Try putting some miles on the car, and see if it improves.

If it doesn't leak there's probably no oil in it.

....so whats involved in changing out the rear main seal? my car still has the original one in it and it will leak a bit at first start up, but once there's heat in the engine it tends to swell up a bit and seal it self shut. this is something i'll be doing myself later on this summer so i'm wondering just how hard is it to swap one out?????......

I have done about 4 of them. A Factory service manual will help a bunch. On a lift I think it took me around 4 hrs to do them.

Hi Joe,so you're saying put in the rear main seal,2 piece neopreme on crank,but instead of the side strips,fill with RTV, Right Stuff ?????? The reason I ask,is that I have heard this before,not just on Buick v6's,but on the BB Mopars to.
Thanks

Put a few beads of The Right Stuff on the back of the block once it's together.
