On the M44 four-cylinder engine in the E36 318i, 318is, 318ti, and the Z3 1.9 from 1996 to 1999, this Original BMW gasket seals the oil line where it meets the valve cover. BMW names the part simply a gasket. It weighs 2 grams and is sold individually, as one seal per order. BMW production of this number began in September 1995. Like any valve cover seal, it relies on some crush or elasticity to fill the gap between two surfaces and keep oil and oil vapor inside the engine.

This seal is specific to the M44. BMW shows it only on that engine. When an M44 valve cover is off for service, this small seal and the cover gasket share the same sealing job at the top of the head. Rubber seals in this area harden and become brittle with age, which eventually lets oil seep at the joint. Overtightening the fasteners can crush a seal past the point where it can still seal. Gasket maker that is not compatible with the seal material can also break it down.
