About this part

Product Details

When you're rebuilding the top end of your GM L42 or L61 Ecotec engine, getting the cylinder head gasket seated correctly is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of modern engines, whether you're working with aluminum heads on an aluminum block or cast iron block.

This gasket uses 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 temperatures up to 482 degrees Fahrenheit and provides a reliable seal without needing additional sealants. The center layer is stainless steel and can be varied in thickness to achieve different compression ratios; this particular gasket has a compressed thickness of .036 inches and an 87mm bore, making it suitable for a range of GM Ecotec applications from 2000 through 2008, including models like the Chevrolet Cobalt, Pontiac Grand Am, and Saturn Ion.
