Cometic Toyota Gen-1/2 5S-FE 87mm .051in MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for Toyota 5S-FE engines, found in Gen-1 and Gen-2 applications. It has an 87mm bore and a thickness of .051 inches, designed to seal the combustion chamber and coolant passages between your engine block and cylinder head. MLS gaskets are known for their durability and ability to handle higher cylinder pressures and temperatures compared to traditional composite gaskets, making them a solid choice for engine rebuilds or repairs where a reliable seal is critical.

Cometic uses multiple layers of stainless steel, along with specialized coatings, to create a gasket that resists stretching and blowout. The precise thickness of .051 inches is important for maintaining the correct compression ratio for your specific engine build. When installing, ensure both the block and head surfaces are perfectly clean and flat, as MLS gaskets require a very smooth mating surface for optimal sealing. Following the manufacturer's torque sequence and specifications is also crucial for proper performance and longevity.
