Product Details
If you're rebuilding the top end of your 1991-1998 BMW 318i, 318is, 318ti, or Z3 with an M42 or M44 engine, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, ensuring a reliable seal between your cylinder head and engine block.
Cometic constructs this gasket using multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with both aluminum and cast iron blocks. The compressed thickness of this gasket is 0.120 inches, with an 85mm bore, making it a direct fit for the specified BMW engines. Because it's an MLS design, it doesn't require any additional sealants, simplifying the installation process.
This gasket is a well-built option for anyone needing to replace their head gasket during an engine repair or rebuild. Ensure your engine is properly sealed and ready for the road.
