1987 BMW M6 Service and Repair Manual

This factory service and repair manual for the 1987 BMW M6 covers a two-door coupe in Base trim built around the 3.5L inline-six, a naturally aspirated gasoline engine with double overhead camshafts. It is a hand-built engine in a standard-looking body, and that combination is exactly why a factory manual matters here: the assembly clearances, timing procedures and torque values that the engine needs are specific to it, and are not shared with the ordinary six-cylinder cars of the period.
