Valve stem seals play a critical role in controlling oil flow to the valve stems as they move within the valve guides. Proper oil control prevents excessive stem and guide wear while avoiding carbon buildup that can lead to valve seat damage, increased oil consumption, and rough engine operation. Each Fel-Pro valve stem seal is engineered to exacting standards using proprietary design and manufacturing processes to ensure a reliable seal on even the most troublesome applications.
