Product Details
If you're rebuilding the top end of your engine, making sure your valve guides are properly sealed is a critical step. These COMP Cams valve seals are designed to keep oil from leaking down the valve stem into your combustion chamber, which can cause blue smoke on startup and fouled spark plugs. They are made with Viton, a material known for its excellent sealing properties and resistance to heat, making them a solid choice for performance applications where engines run hotter.
This particular seal, part number 520-1, features a metal body for added strength and a precise fit. It's built to work with 5/16 inch valve stems and valve guides that are 0.530 inches in outer diameter. The 0.575 inch outer diameter of the seal itself ensures a snug fit into the valve guide. Using the right size seal is important for preventing oil consumption and maintaining good compression.
