J.C. Whitney RD31290005 OEM Replacement Valve Cover Gasket for Ram 5.9L/6.7L Cummins Diesel

The J.C. Whitney RD31290005 is an OEM replacement valve cover gasket engineered for Ram full-size trucks equipped with the 5.9L and 6.7L Cummins ISB turbo diesel engine. Designed to restore a factory-quality seal between the valve cover and cylinder head, this gasket is a direct-fit solution for addressing oil leaks caused by heat cycling, age, and normal wear.

Over time, the factory valve cover gasket can degrade due to sustained heat and pressure exposure, resulting in oil seepage along the side of the engine block. Replacing the gasket with a properly spec'd OEM-grade component eliminates leaks and helps maintain crankcase pressure integrity. Installation torque for the 5.9L/6.7L Cummins valve cover bolts is 18 ft-lbs (24 N·m) — always allow the engine to cool completely before beginning work.

Key Features:

• OEM replacement specification — direct fit, no modifications required
• Engineered to seal the valve cover-to-cylinder head interface on 5.9L and 6.7L Cummins ISB diesel engines
• Restores proper crankcase pressure sealing and prevents oil leaks
• Compatible with Ram 2500/3500 full-size trucks from 2003 through 2020
• High-temperature resistant gasket material formulated to withstand diesel engine heat cycles

Whether you are performing routine preventative maintenance or addressing an active oil leak, the J.C. Whitney RD31290005 valve cover gasket provides a reliable, cost-effective OEM-style repair for your Cummins diesel.
