Disadvantages, breakdowns and problems of OM601
These diesel engines are very reliable, provided that high-quality fuel and oil are used.
Cheap lubricants quickly wear out pump parts, as well as hydraulic lifters.
Contaminated antifreeze often leads to engine overheating and breakdown of the cylinder head gasket
Weak point in the fuel system - centrifugal clutch of the injection advance angle
The timing chain serves 200 - 250 thousand km, and if it breaks, the block head may crack
