Fel-Pro Ford Ranger SS 70964 Engine Valve Stem Oil Seal Set

If you're rebuilding the top end of your 1999-2008 Ford Ranger, replacing the valve stem seals is a crucial step. These seals sit on the valve guides and prevent oil from seeping past the valve stems into the combustion chamber. When they wear out, you'll often notice blue smoke from the exhaust, especially on startup or deceleration, and your engine can start burning oil.

Fel-Pro designs these valve stem seals specifically for the repair environment, meaning they account for imperfect sealing surfaces that can sometimes be found during an engine rebuild. They use application-specific materials, whether that's an umbrella-style seal to deflect oil or a positive seal for a tighter fit. This set includes an installation tool to help protect the inner lip of the seal as you press it onto the valve guide, which is a common point of damage during installation. This helps ensure a reliable seal for your engine repair.
