Cometic GM Ecotec 2.2L DOHC (L61/L42) 87MM .030 inch MLS Head Gasket

This product is a Cometic Multi-Layer Steel (MLS) head gasket specifically sized for GM Ecotec 2.2L DOHC engines with an 87mm bore, designed to be installed at a compressed thickness of .030 inches. It's built to handle the demands of higher output engines, offering a strong seal without needing additional sealants. This gasket is suitable for applications using aluminum heads with either aluminum or cast iron blocks, as its construction can manage the different expansion rates between these materials.

The gasket is constructed from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material rated up to 482°F (250°C), which ensures a reliable seal even in harsh conditions and across various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness control. This well-built design helps prevent leaks and maintain compression.

This gasket fits a range of GM vehicles, including models like the Chevrolet Cobalt, Pontiac G5, and Saturn Ion. Always refer to the manufacturer's installation instructions for proper fitment and procedures.
