🔍 Rear Engine Main Seal Set - Fel-Pro BS 11829-1: Optimize Your Search Review

Pros: Arrived on time, fits as stated, instructions included Cons: Didn't stop the leak but might have slowed it down a bit

I bought this for my 1979 Vette which still had the original rear seal and was losing oil fairly constantly. Installation was easy, just make sure the lip of the gasket is facing the right direction or you'll have to reinstall the gasket. No more drops flow, very satisfied.

I was able to fit a new gasket with the shoehorn, but the lip of the block sheared off the back of the gasket slightly - I highly recommend deburring this lip before you start installing the gasket around the crank into…

Lots of information on the web about old cranks that have a worn groove on the rear main sealing surface. Replacing a leaking rear main oil seal with the exact same seal or a different brand seal made to OEM specifications will ensure the leak returns quickly. This gasket is designed so that the sealing lip is offset from the position normally specified by the OEM (in this case a GM/1981 Chevy 350 block). When the sealing lip is moved a few mm, the lip slides over the fresh sealing surface…
