Fel-Pro 459 RR Engine Valve Stem Oil Seal

This is the Fel-Pro 459RR valve stem oil seal. It's a direct replacement part designed to keep oil from leaking down the valve stem into the combustion chamber. When these seals wear out, you'll often notice blue smoke puffing out of your exhaust, especially on startup or when you let off the gas. Replacing them is a common repair to help restore your engine's performance and reduce oil consumption.

Fel-Pro is known for making well-built parts that fit right the first time. This seal is made from a durable material that can withstand the heat and oil exposure inside your engine. It's a straightforward part to replace, often done with the cylinder head removed or sometimes with specialized tools while the head is still on the engine, depending on your specific application.
