• Intake manifold sealing issues that can trigger vacuum leaks
• Exhaust manifold sealing problems that can create noise or exhaust odor
• Oil seepage at related engine sealing surfaces

Installation Notes and Tips

Confirm engine code and exact vehicle application before installation. Fits 1995-1996 Buick Century, N/A and 1997-1999 Chevrolet Malibu, N/A among other listed GM models, so match the vehicle year and configuration carefully. Cylinder head bolts are not included, and torque-to-yield fasteners are specified, so replacement bolts are recommended during service. The notes also indicate that the exhaust pipe gasket is not included.

Clean all mating surfaces thoroughly, inspect the cylinder head for warpage, and follow the factory torque sequence and angle procedure during assembly. Replace any worn seals or related gaskets during the repair to help maintain a proper seal.
