Fel-Pro 433 RR Engine Valve Stem Oil Seal

Fel-Pro is well-known for making dependable gaskets and seals that fit right the first time. This 433RR valve stem oil seal is a prime example, designed to keep oil from getting into your engine's combustion chambers through the valve guides. When these seals start to wear out, you might notice blue smoke coming from your exhaust, especially on startup or when you let off the gas. Replacing them is a common part of rebuilding an engine's top end or addressing oil consumption issues.

This seal is made from a durable material that holds up well against engine oil and heat. It's a straightforward replacement part that helps restore your engine's proper operation by preventing excess oil from reaching the valves and cylinders. Installing these seals is typically done when the cylinder head is off the engine, making it a good time to address other valve train components.
