What does the .120 inch thickness signify?

The .120 inch thickness refers to the compressed gasket height. This specific thickness is often chosen for engine builds where slight adjustments to compression ratio or valve timing might be desired, or to match other components in the engine assembly.

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

Viton is a high-performance synthetic rubber known for its excellent resistance to heat and various fluids like oil and coolant. Coating the outer layers with Viton helps create a more robust seal, especially in areas exposed to high temperatures and aggressive engine fluids.

Does this head gasket come with installation hardware?

This product is for the head gasket only. It is recommended to consult the manufacturer's installation instructions or your vehicle's service manual to determine if new head bolts or other hardware are required for proper installation.

About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for the 1984-1986 Nissan 200SX equipped with the CA18DE or CA18DET DOHC engine. It features an 85mm bore and a .120 inch thickness, designed to create a strong seal between your engine block and cylinder head. A properly sealing head gasket is crucial for maintaining compression, preventing coolant and oil leaks, and ensuring your engine runs smoothly.

Cometic builds these gaskets with multiple layers of stainless steel for durability and consistent clamping force. The outer layers are coated with Viton, a high-performance synthetic rubber that handles heat and fluids well, helping to create a reliable seal even under demanding conditions. This construction helps resist gasket failure and blowouts, which is important when you're working on an engine that might see spirited driving or performance modifications.

This gasket is a direct fit for the specified Nissan models. When installing, always refer to the manufacturer's service manual for proper torque sequences and specifications to ensure the best possible seal and longevity for your engine rebuild.
