Cometic GM Ecotec 2.2L DOHC 89mm Bore .040 inch MLS Head Gasket - L61/L42 Motor

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically made for GM Ecotec 2.2L DOHC engines with L61 or L42 motors. It features an 89mm bore and a compressed thickness of 0.040 inches. This gasket is designed to provide a strong seal between the cylinder head and the engine block, which is crucial for maintaining compression and preventing coolant and oil leaks, especially in higher-output applications.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.040 inches on this particular gasket. Because they are MLS, these gaskets don't require any additional sealants, simplifying installation.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Cobalt, Pontiac G5, and Saturn Vue. It's a well-built component that helps ensure your engine runs smoothly and reliably.
