The BMW M42 is a DOHC 16-valve I4 piston engine first built for the E30 318is 1989 year model. The engine block is based on the BMW M40, used on the 318i, but had distinctive features such as double overhead cams driven by a timing chain, hydraulic valve lifters, and an increased 10:1 compression ratio.

Profile gaskets on M42s built before 1993 are known to fail prematurely.
