BMW M30

The "big six" BMW M30 is an inline-6 cylinder engnine built by BMW and used in many of its cars, such as the BMW 535i. BMW's 3.5L straight six cylinder motors had the longest production run of any BMW engine, dating back to the 1968 E3 and E9 cars. The last use of the block was the 1993 E34 535i. Displacement ranges from 2.5 to 3.5 liters with a 100 mm bore spacing.
The 3.5L engine is 'bulletproof' and a true workhorse. Instead of the more common timing belt, the M30 had a timing chain designed to last the life of the engine. With regular oil changes and maintenance they have routinely lasted 250,000 miles or more.
