• Service issues on GM engines using molded rubber valve cover sealing

Installation Notes and Tips

Clean the valve cover and cylinder head sealing surfaces thoroughly before installation. Inspect the cover for warpage or damage, and replace any worn sealing surfaces before fitting the new gasket. This set does not include PCV valve grommets, camshaft plugs, spark plug tube seals, or valve cover grommets, so confirm the engine’s sealing requirements before assembly.

For the listed Chevrolet S10, GMC Sonoma, Buick Century, and other GM applications, follow the engine-specific service procedure and torque sequence to help the molded rubber gasket seat evenly. The fitment notes for some applications reference using the included gasket from the set during thermostat seal installation.
