Valve Cover Gasket and Harness Kit for Dodge Ram 2500 3500 (2006-2010) 5.9L 6.7L

Direct-Fit Valve Cover Gasket and Harness Kit for 2006-2010 Dodge Ram 2500, Ram 3500 (DR/DH)

What it Does: The Valve Cover Gasket and Harness Kit provides a reliable oil seal and integrated pass-through electrical connection for the fuel injectors on the 2006-2010 Ram 2500, Ram 3500 to prevent oil leaks and eliminate injector misfires.

The Stock Dodge Ram 2500, Ram 3500 Pass-Through Connector Degradation

Factory valve cover gaskets on the DR/DH platform house internal wiring that delivers power to the common-rail fuel injectors. Over time, prolonged exposure to engine thermal cycling and hot oil causes the stock elastomer gasket to harden and weep oil across the cylinder head. Concurrently, the integrated pass-through electrical pins and plastic connector housings brittle, corrode, and suffer from micro-arcing. This electrical resistance leads to intermittent injector open-circuit trouble codes (e.g., P0201-P0206), rough idling, and sudden cylinder contribution loss under heavy towing loads.

The Engineering Solution

This replacement assembly combines a high-grade molded elastomer perimeter seal with a heat-resistant integrated injector harness. Designed to exceed OEM thermal retention specs, the oil-impervious polymer body isolates the internal electrical traces against oil saturation. Heavy-duty copper terminal pins provide uninterrupted current transmission to the solenoid injectors under high thermal stress. Included pigtails and butt connectors allow technicians to replace melted or brittle external harness plugs, restoring clean continuity and a leak-free seal without requiring a complete engine harness replacement.
