The Story
Are you noticing blue smoke at startup or increased oil consumption in your 5.9L Cummins? The MAHLE Valve Stem Seal Kit is designed to restore proper oil control in the valvetrain of your 5.9L/6.7L Cummins engine. Over time, factory valve stem seals can harden or wear out, allowing engine oil to slip past the valve guides and enter the combustion chamber. This leads to oil burning, excessive smoke, and reduced engine efficiency. Replacing them with the SS46108 seal kit helps maintain proper lubrication control, reduce oil consumption, and keep your Cummins running clean, whether you're performing a cylinder head service or a full engine rebuild.
The MAHLE SS46108 is built with OE-quality materials and precision manufacturing to ensure reliable sealing and long service life. Each set includes 24 valve stem seals covering both intake and exhaust valves on the 24-valve Cummins cylinder head. These seals are engineered to maintain consistent contact with the valve stem while resisting heat, pressure, and chemical exposure inside the engine. Designed as a direct factory replacement, they meet stock specifications and provide the durability and performance trusted by OEM manufacturers and professional engine builders.
