Mr. Gasket 17 Timing Cover Seal

Mr. Gasket Timing Cover Seals are manufactured from a special nitrile rubber and a high-density cork/rubber blend that guarantees a total seal. Engineered specifically for big-block Chevys, they're a direct replacement for Original Equipment seals and ideal for both high-performance and racing applications. They're durable, specially designed not to shrink or stick, and a crucial part of any timing-chain or cam swap.
