VALVE STEM OIL SEAL. The valve stem oil seal is a component of the engine valve train designed to regulate the amount of engine oil supplied to the valve guides while preventing excess oil from entering the combustion chamber. The seal is installed on the valve guide and forms a tight interface with the valve stem, allowing lubrication of the guide while limiting oil flow. The component typically consists of a metal outer shell and a heat-resistant rubber sealing element with a tension spring that maintains constant pressure against the valve stem. During engine operation the seal moves with the valve and meters oil supply to the guide. Worn valve stem seals may cause increased oil consumption, blue exhaust smoke, oil deposits on spark plugs and contamination of the combustion chamber. Our catalog includes genuine OEM valve stem oil seals and quality replacements for various engine types. Selection is based on VIN number, engine specification and valve stem dimensions. Proper replacement ensures correct oil control and stable engine operation.
