Are valve stem seals necessary?
Different than different seals withinside the engine, valve stem seals play an crucial position in lubrication. Valve stem seals permit a managed quantity of oil to lubricate the valve stem because it movements withinside the valve manual. The quantity of oil that passes through the valve stem seal have to be exactly managed. Too little oil reasons stem and manual wear; an excessive amount of oil reasons carbon buildup main to valve seat damage, lower in volumetric efficiency, extended emissions, catalytic converter degradation and immoderate oil consumption.
