What does a cylinder head gasket do?

A cylinder head gasket seals the space between your engine's cylinder head and the engine block. It's critical for keeping coolant and oil from mixing and preventing combustion gases from escaping the cylinders.

Why is the gasket specified as 'Left'?

Engines with multiple cylinder heads, like the Subaru Boxer engine, have a left and a right side. This gasket is specifically designed to fit the cylinder head on the left bank of the engine.

What is a multi-layer steel (MLS) gasket?

MLS gaskets are made from several layers of steel with a specialized coating. This construction makes them very strong and resilient, able to handle the high pressures and heat found in modern engines.

Product Details

This Victor Reinz cylinder head gasket is made from a multi-layer steel (MLS) design, a common and effective choice for sealing the combustion chambers in your Subaru's engine. MLS gaskets are well-built to handle the high pressures and temperatures found between the cylinder head and the engine block, helping to prevent coolant and oil leaks, as well as combustion gases escaping where they shouldn't. This gasket is specifically for the left side of the engine.

When you're rebuilding the top end of your engine or replacing a blown head gasket, using a well-made gasket like this one from Victor Reinz is important for ensuring a proper seal. The multi-layer steel construction offers good resilience against compression and heat cycles, which helps maintain the seal over time. It's designed to fit your Subaru Outback, Legacy, or B9 Tribeca directly, making installation straightforward if you're familiar with engine work.

Make sure to follow the manufacturer's installation instructions carefully, as proper torque sequencing and fastener tightening are critical for the longevity of any head gasket installation.
