Victor SS45885 Engine Valve Stem Seal Set for Mack E7 Engines

The Victor SS45885 is a complete engine valve stem oil seal set engineered specifically for Mack E7 diesel engines. Valve stem seals play a critical role in controlling oil consumption and protecting the combustion chamber — a worn or damaged seal allows oil to be drawn down the valve guides and into the cylinders, resulting in excessive oil consumption, blue smoke at startup, and potential engine damage.

Key Features:

• Complete valve stem seal set with enough seals to service all intake and exhaust valves on one engine
• Precisely engineered to OE specifications for accurate fit and reliable sealing performance
• High-quality elastomer construction providing excellent chemical resistance and wide operating temperature tolerance
• Prevents oil from the cylinder head from entering the combustion chamber
• Controls proper valve stem lubrication to protect valve guides from wear
• Low breakaway torque after standstill for smooth, consistent operation
• Designed and manufactured by Victor (a MAHLE brand), a trusted OE supplier to major engine manufacturers worldwide

The SS45885 valve stem seal set is a direct-fit solution for Mack E7 diesel engine applications, restoring proper oil control and engine efficiency. Replacing worn valve stem seals at the first sign of excessive oil consumption or blue exhaust smoke can prevent more costly engine repairs down the road.
