Cometic GM L42/L61 Gen-1/2 ECOTEC .075in MLS Cylinder Head Gasket - 87mm Bore

This Cometic head gasket uses a multi-layer steel (MLS) construction, featuring three to five layers of stainless steel. Stainless steel is chosen for its strength, its ability to rebound under pressure, and its resistance to corrosion, which is crucial for a long-lasting seal in the demanding environment of an engine's combustion chamber. This gasket is designed with an 87mm bore and a .075 inch thickness, suitable for a range of GM Ecotec L42 and L61 Gen-1/2 engines.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material rated up to 482°F (250°C). This coating helps the gasket meet the challenges of various sealing conditions, load requirements, and surface finishes found in modern engines. It's a well-built component designed to maintain a tight seal, helping to prevent coolant and oil leaks between the cylinder head and the engine block.

This gasket fits a variety of GM vehicles, including models like the Chevrolet Cavalier, Cobalt, HHR, Malibu, Pontiac Grand Am, Sunfire, and Saturn Ion, among others. Ensure you check the full fitment list to confirm compatibility with your specific vehicle.
