Valve Stem Seals, supplied by NWB, provide a defined rate of oil to the valve stem interface of internal combustion engines to lubricate the valve guide and to minimize engine emissions. The valve stem seal prevents oil from the cylinder head entering the combustion chamber. Worn valve stem seals risk starving the guides for lubrication or flooding the engine with oil
