Valve Stem Seal by Volvo Penta (3861317)

To lubricate the valve guide and reduce engine emissions, valve stem seals deliver a precise metering rate of oil to the valve stem contact of internal combustion engines. Too much oil results in carbon buildup on piston tops, which can cause detonation/pre-ignition problems, increased emissions, catalytic converter deterioration, and excessive wear on the stem and guide. These seals, which have a low friction design, can resist high pressures in the engine's exhaust and intake ports, enhancing engine performance and improving emissions quality. With the use of valve stem seals, the valve stem may be maintained lubricated as it passes through the valve guide. Minimizes product loss, reduces environmental pollutants, and offers years of dependable service.
