How does Rislone Rear Main Seal Repair work?

This product works in two ways to help solve most any seal type leak.

1) The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.

2) The seal polymer works by building a polymeric film around the rear main seal and also filling in any groove worn into the crankshaft by the seal.

Will Rislone Rear Main Seal Repair work on other oil leaks?

Yes. Even though it is specially designed to seal rear main leaks, it also works better than a conventional stop leak on all other engine oil leaks. This includes the timing cover seal, cam seals, O-rings and other seals and gaskets.

Will Rislone rear Main Seal Repair clog my oil filter?

No. Unlike our cooling system products, Rislone Rear Main Seal Repair has no particles to plug the leak. It contains special polymers and seal conditioners to stop seal leaks.
