Keep your oil from escaping with rear main seals from Cometic Gasket. If you have a wet spot on the rear of your oil pan, spots on your driveway, or garage floor, or worse, an oil-covered transmission, then you'd better get rear main seals from Cometic.

When you need superior gaskets for your high performance vehicle, Cometic has the gaskets and rear main seals to fit your application.
