What is the compressed thickness of this head gasket?

The compressed operating thickness of this Cometic MLS head gasket is .040 inches. This measurement is important for ensuring the correct compression ratio and valve-to-piston clearance after installation.

Do I need to use any sealant with this gasket?

No, this Cometic Multi-Layer Steel (MLS) head gasket is designed to provide a reliable seal on its own and does not require any additional sealants. The Viton coating on the outer layers helps create a tight seal.

What is the benefit of the Viton coating on the gasket?

The Viton rubber coating on the outer layers of the gasket is heat resistant up to 482°F (250°C). This material is chosen to withstand the harsh conditions found in high-output engines and provides a robust seal against combustion gases and fluids.

About this part

Product Details

If you're rebuilding the top end of your 1988-1993 Toyota Celica, especially if it's a 3S-GE or 3S-GTE engine, a solid head gasket is crucial for proper sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines.

This gasket uses multiple layers of stainless steel for strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with both aluminum and cast iron engine blocks. The compressed thickness of this gasket is .040 inches, which is a common size for engine rebuilds. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

This gasket is designed to fit engines with an 87mm bore. It's a well-built option for ensuring a good seal between your cylinder head and engine block.
