What is the main advantage of a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets offer superior sealing performance due to their multiple stainless steel layers. They are strong, resist corrosion, and can handle the shearing forces created when mating different metals like aluminum and cast iron.

Does this gasket require any additional sealants?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a tight seal on its own.

What does the .018 inch thickness refer to?

The .018 inch measurement refers to the compressed operating thickness of the head gasket. This thickness is important for maintaining the correct compression ratio and valve timing in your engine after installation.

About this part

Product Details

If you're rebuilding the top end of your 2002-2005 Subaru Outback's EZ30 flat-6 engine, a reliable head gasket is crucial. This Cometic Multi-Layer Steel (MLS) gasket is specifically designed for the left bank of your engine, featuring a 90mm bore and a compressed thickness of .018 inches. MLS gaskets are known for their strength and ability to seal effectively, even between dissimilar metals like aluminum heads and cast iron blocks, which is common in modern engines.

This gasket is constructed with multiple stainless steel layers for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating ensures a strong seal in demanding conditions and works well with various surface finishes on your cylinder head and block. The center layer is uncoated stainless steel, allowing for precise thickness control, and this particular gasket is .018 inches thick when compressed, making it suitable for many rebuilds without needing special adjustments.

Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process. This makes it a solid option whether you're working with aluminum heads on aluminum blocks or aluminum heads on cast iron blocks. Just be sure to use the correct gasket for the left side of your EZ30 engine.
