Engine components are vital to your vehicles operation, keep your vehicle running properly by making sure your engine components are in good condition and replaced when needed.
Valve stem seals are designed to prevent the mixture of air and oil within your vehicles combustion chamber. Over time, your vehicles valve stem seals can wear out and your vehicle will begin to burn oil. If your vehicle is burning oil or you are rebuilding your engine, we recommend replacing your valve stem seals.
