Are you noticing blue smoke at startup or higher oil consumption in your 6.7L Powerstroke? The MAHLE Valve Stem Seal Set is designed to restore proper oil control in your engine’s valvetrain, preventing oil from leaking past the valve stems and into the combustion chamber. Worn valve stem seals are a common cause of oil burning, smoke, and reduced engine efficiency, especially on high-mileage diesel engines or during top-end rebuilds. Replacing them with a high-quality seal set helps maintain clean combustion, reduce oil consumption, and keep your Powerstroke performing the way it should, whether you're towing, daily driving, or completing a full engine service.

The MAHLE SS46062 valve stem seals are manufactured from a durable fluoroelastomer and engineered to withstand the extreme heat, pressure, and chemical exposure found in modern diesel engines. Precision-molded for an OE-quality fit, these seals maintain consistent contact around the valve stems to prevent oil intrusion while allowing proper valve movement. Each set contains 32 valve stem seals to service the entire engine and is built to meet or exceed original equipment specifications, ensuring long-lasting durability and dependable sealing performance.
