About this part

Product Details

Manley Performance is well-known for making high-performance internal engine components, and these valve stem oil seals are a prime example of their focus on quality. If you're rebuilding your engine or just replacing worn-out seals, these are designed to keep oil from getting into your combustion chambers. They seal around the valve stem, which is crucial for preventing oil burning and maintaining proper engine compression.

These seals are made to fit valve stems that are .274 inches or 7mm in diameter. When you're installing them, make sure the seal sits flush on the valve guide. A good seal here means less oil smoke out the exhaust and a cleaner burn inside your engine.
