Cometic GM Ecotec 2.2L DOHC (L61/L42) 87MM .045 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. With a compressed operating thickness of 0.045 inches, it's designed to handle the demands of high-output engines and provides maximum sealing performance without needing additional sealants. This gasket is a solid choice for mating aluminum heads to either aluminum or cast iron blocks, as it can effectively manage the shearing forces that arise between dissimilar metals.

The strength of MLS gaskets comes from their layered stainless steel construction, which also offers good rebound characteristics and resistance to corrosion. The Viton coating on the outer layers is a heat-resistant material, capable of withstanding temperatures up to 482°F (250°C), making it suitable for harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This gasket fits a range of GM vehicles, including models like the Chevrolet Cobalt, Pontiac Grand Am, and Saturn Ion.
