Disadvantages, breakdowns and problems of the internal combustion engine M120
This is a hot motor and with a lack of cooling, its gaskets quickly collapse.
And then, through all the collapsed gaskets and seals, grease begins to ooze
A lot of headaches for owners are delivered by the Bosch LH-jetronic control system
The two-row chain only looks powerful, sometimes it stretches to 150 km
But most of the complaints are about high fuel consumption and the considerable cost of spare parts.
