Fel-Pro Toyota Prius SS 72913 Engine Valve Stem Oil Seal Set

If you're rebuilding the top end of your engine, replacing the valve stem seals is a common and important step. These seals keep oil from leaking down the valve guides into the combustion chamber, which can cause blue smoke on startup and increased oil consumption. This set from Fel-Pro is designed to fit a range of vehicles, including popular models like the Toyota Prius, Scion xB, and Toyota Yaris.

Fel-Pro knows that engine repairs happen in the real world, often on surfaces that aren't perfectly smooth. That's why their valve stem seals are application-specific, using the right type of seal—whether it's a deflector, O-ring, or positive seal—to ensure a reliable fix. They use materials chosen for each specific vehicle to give you a solid seal. Plus, they include a helpful installation tool to protect the seal's inner lip during installation, making the job a bit easier and helping to prevent damage.
