About this part

Product Details

When you're rebuilding the top end of your engine, getting the valve seals right is crucial for keeping oil out of the combustion chamber. These valve stem oil seals from Manley Performance are designed for 11/32 inch valve stems, a common size in many performance and stock applications. Properly sealing the valve guides helps maintain consistent oil pressure and prevents excessive oil consumption, which can lead to smoking and fouled spark plugs.

Manley is known for making well-built internal engine components, and these seals are no exception. They are made to handle the heat and stress inside the engine, ensuring they do their job effectively. Installing these seals correctly is a key step in ensuring your engine runs cleanly and efficiently after the rebuild.
