Valve stem seals are critical engine components that control the amount of oil allowed to lubricate the valve stems while preventing excess oil from entering the combustion chambers. Worn seals can lead to increased emissions, reduced fuel efficiency, and visible exhaust smoke. Corteco valve stem seals are manufactured to exacting OEM specifications and are often the same parts used in original equipment assembly. This kit provides reliable, long-lasting performance for professional rebuilds and DIY cylinder head restoration projects.
