What It Is Used For

• Oil leaking from the valve cover perimeter
• Oil residue on the cylinder head or exhaust side of the engine
• Seepage after valve cover removal and reinstallation
• Loss of sealing integrity on aging molded rubber gaskets
• Maintenance on GM V6 engines in Buick, Chevrolet, Oldsmobile, and Pontiac vehicles

Installation Notes and Tips

Clean the valve cover and cylinder head sealing surfaces thoroughly before installation. Inspect the cover for warpage, cracks, or contamination that could affect sealing. Because grommets, spark plug tube seals, PCV valve grommet, and camshaft plug are not included, verify the engine’s sealing components before reassembly. Confirm vehicle application by year, make, and model before ordering.
