COMP Cams Valve Seals 3/8 Viton Metal Body

COMP Cams is a well-known name in the performance valvetrain world, and these valve seals are a solid option for anyone rebuilding or upgrading their engine. They're designed to keep oil from getting past the valve guide and into the combustion chamber, which helps prevent smoking and oil consumption. If you're working on an engine that needs new valve seals, especially one that sees some spirited driving, these are worth a look.

These particular seals use Viton material, which is a popular choice for performance applications because it holds up well to heat and chemicals. The metal body construction adds a layer of durability and helps ensure they seat properly. They're made to fit valve stems that are 3/8 inch and valve guides that are 0.500 inch in diameter, with an outer diameter of .545 inches. This specific sizing is important for getting a good seal and maintaining proper spring clearance.

When you're installing these, make sure the valve guides are clean and within the specified diameter. Getting a good seal here is crucial for engine health and performance.
