Product Details

If you're working on the engine of your 1977-1979 BMW 320i, specifically the M20 2.5L or 2.7L engine, this Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the job. It's designed to create a strong, reliable seal between your cylinder head and engine block, which is crucial for keeping your engine running smoothly and preventing leaks.

This gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different block and head materials, including aluminum and cast iron. The compressed thickness of this gasket is 0.120 inches, and the bore size is 81mm, matching the specifications for the M20B20 engine. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
