Valve Stem Seals
Valve stem seals play a critical role in controlling valve lubrication as well as oil consumption. If the seals do not fit properly or are not installed correctly, the guides may be either starved for lubrication or flooded with oil. Either way, the engine is going to have problems – and you’re going to have
