Valve cover and valve cover sealThe new seal utilizes a unique sealing design and retention ribs. This design improves the sealing area of the seal. This design is also less likely to be displaced during the assembly process. The new seals are a direct replacement for the former seals. The seals will fit into existing covers without any modification to the covers.
