Valve Stem Seal for OM457 EEV
Detroit Diesel

This steel valve stem seal for the OM457 EEV engine is designed to provide a durable, high-performance barrier that prevents oil from leaking along the valve stem. Its 11.5-inch length ensures a secure fit, effectively sealing the valve guide during engine operation. The robust steel construction offers excellent resistance to high temperatures, chemical exposure, and mechanical wear, making it ideal for demanding heavy-duty applications. Proper sealing reduces oil consumption and prevents oil from entering the combustion chamber, which could cause fouling, smoking, and increased emissions. Maintaining this seal is key to preserving engine efficiency, reducing maintenance costs, and meeting environmental regulations. When selecting replacement parts, Source One Parts Center supplies this high-quality valve stem seal, ensuring your engine maintains optimal performance and reliability over time.
