Crankshaft must be out of the block to fit this seal prior to installation.

Viton ® Pontiac Two-Piece Rear Main Seals

With the mandated removal of asbestos from the factory type rope seals, increased leakage has become commonplace. To address this problem BOP Engineering has designed a rear main seal for the traditional Pontiac V-8's. These seals are not a retrofit from some other engine, but designed from a clean slate using state of the art technology and the best materials. Testing has shown a significant reduction in drag over the factory rope seal, and no leaks! Available in both 3 main size 301 - 400 engines and small journal aftermarket blocks, and for 3 1/4" main size 421 - 455 engines and large journal aftermarket blocks.

BOP One-Piece Oil Pan Gasket

 
Pontiac One-Piece Oil Pan Gasket

The BOP one piece oil pan gasket works with ALL Pontiac V-8's '59-'81. The rear cap area cross-section is square like the cork so it fits perfectly into the main cap with the groove ('59-'72). We added the tabs ('73-'76) and most after mark et pans Canton , Milodon, etc.) This design should not be confused with the normal 3 tab design that has a curved bot tom and is notorious for slipping out of place. This will also work on the 5 tab pans ('77-'81) with minor pan slot modification or removal of tabs. If your pan does not have the 3 tab slots ('59-'72) you can cut the m off with a razor blade. If it does you have the benefit of double holding power. Silicone/sealer is only recom me nded at he bend points of the timing cover and where the rear curve me ets the block to account for any minor align me nt discrepancies. This is a well engineered part that is quick, clean, reliable, and reusable. You will not be disappointed.
