85mm MLS Head Gasket .070 - BMW M20 2.5/2.7L

The 85mm MLS Head Gasket .070 – BMW M20 2.5/2.7L from Cometic Gaskets is a precision cylinder head gasket engineered for BMW inline-6 engines requiring critical sealing integrity. This gasket is essential for engine builders, performance enthusiasts, and mechanics restoring or rebuilding M20-series powerplants to factory or modified specifications. Proper head gasket selection directly impacts compression retention, coolant and oil containment, and long-term engine reliability.

This 85mm bore gasket features multi-layer steel (MLS) construction with a 0.070-inch compression thickness, a proven design that withstands combustion pressures and thermal cycling without deformation or leakage. MLS gaskets use stainless steel layers with elastomer-coated surfaces to distribute clamping load evenly across the combustion chamber and fluid passages, making them far superior to traditional single-layer gaskets. The 0.070-inch thickness is precisely calculated to restore correct deck height and compression ratio when replacing an original gasket in M20 2.5L and 2.7L configurations, critical for fuel mapping and ignition timing accuracy.

BMW M20 owners performing head gasket replacement, cylinder head resurfacing, or complete engine rebuilds depend on this gasket to prevent post-installation leaks and maintain peak performance. Installation requires proper head bolt torque sequence and factory specifications; verify your engine's deck and head condition before assembly. Whether you're addressing a failed original gasket or upgrading to premium sealing during a rebuild, Cometic's MLS design delivers the durability and pressure retention demanded by inline-6 enthusiasts.
