What does the .030 inch undersize mean for this head gasket?

The .030 inch undersize specification means the bore of this gasket is slightly smaller than a standard bore. This is often used when engine components like pistons or sleeves have been machined or replaced with slightly different dimensions.

What is Viton and why is it used on this gasket?

Viton is a type of synthetic rubber known for its excellent resistance to heat and chemicals. Coating the gasket with Viton helps create a robust seal that can withstand high engine temperatures and harsh operating environments.

Can this gasket be used with aftermarket engine sleeves?

Yes, this Cometic head gasket is specifically designed to work with both stock engine blocks and aftermarket Darton sleeves, offering flexibility for engine builds.

About this part

Product Details

If you're rebuilding the top end of your 2003-2018 Toyota 4Runner, or any of the other compatible Honda and Toyota models, a quality head gasket is crucial for a reliable seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of your engine, ensuring proper compression and preventing coolant and oil leaks between the cylinder head and the engine block.

Cometic constructs this gasket using three to five layers of stainless steel. This material choice offers increased strength and resilience, helping the gasket maintain its seal under various operating conditions. The outer layers are treated with an embossed pattern and coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). This specific gasket features a 90mm bore and is .030 inch undersize, making it suitable for stock blocks or those fitted with Darton sleeves.
