Engine Overview and Common Failures

The weight of the M120 engine according to the catalog is 300 kg. The engine number, M120, is located at the junction of the block and the gearbox. This is a hot engine, and its gaskets quickly deteriorate in case of insufficient cooling. Afterwards, lubrication starts leaking through all the damaged gaskets and seals. The Bosch LH-jetronic control system causes a lot of headaches for owners. The double-row chain may seem powerful, but sometimes it wears out as early as 150,000 km. However, the most common complaints are about the high fuel consumption and the considerable cost of spare parts.
