Timing Cover Seal Dodge Cummins

The Timing Cover Seal for Dodge Cummins diesel engines is a critical OEM-specification rubber seal engineered to prevent oil leakage at the engine's front cover. Manufactured by MAHLE ORIGINAL/CLEVITE, a globally recognized leader in engine sealing components, this seal serves owners and technicians who demand factory-quality reliability when servicing Cummins-powered vehicles. Whether you're performing routine maintenance, addressing an oil weep, or rebuilding the front end of your engine, a properly seated timing cover seal is essential to maintaining engine integrity and preventing costly contamination of the timing chain drive.

This rubber seal is precision-molded to exact OEM specifications and sits in the grooved timing cover cavity where it creates a static, oil-tight barrier between the cover and engine block. The elastomeric rubber compound is formulated to withstand sustained exposure to hot diesel oil and thermal cycling without hardening, cracking, or losing compression set—critical durability factors in turbocharged Cummins applications where temperatures and pressures regularly exceed stock gasoline engine levels. Compact dimensions of 6.4 x 2.35 x 6.5 inches and a lightweight profile of 0.44 lbs make installation straightforward, requiring only careful alignment and hand-seating without specialized tools in most cases.

Dodge Cummins owners—from light-duty 6.7L operators to fleet managers overseeing heavy-duty applications—benefit most from OEM seals when addressing slow oil seeps or during scheduled timing cover removal. Proper installation requires a clean mating surface and careful attention to the seal's seating depth to ensure full contact throughout the groove. This seal is sold individually per unit and carries the manufacturer's confidence in matching original Dodge Cummins specifications, making it the definitive choice for owners who refuse compromise on engine reliability and resale value.
