Cometic GM Ecotec 2.2L DOHC (L61/L42) 87MM .027 inch MLS Head Gasket

Cometic Gasket is well-known for making dependable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for GM Ecotec 2.2L DOHC engines, specifically those with L61 or L42 engine codes, and features an 87mm bore with a compressed thickness of .027 inches. This gasket is designed to handle the demands of modern engines, whether you're working with aluminum heads on an aluminum block or aluminum heads on a cast iron block, as it can manage the shearing forces that arise between different metals.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel, which not only adds strength but also allows the gasket to rebound and resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is tough and can handle harsh sealing environments, varying load conditions, and different surface finishes. The center layer is also stainless steel and can be varied to achieve different thicknesses, like the .027 inches found in this particular gasket.

This head gasket fits a wide range of GM vehicles, including models like the Chevrolet Cobalt, Pontiac Grand Am, and Saturn Ion. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward. Just ensure you're following the manufacturer's installation instructions for proper torque sequence and values.
