The dry weight of the M 48.51 engine according to the catalog is 236 kg. The engine number M48.51 is located at the junction of the block and the oil pan, facing downwards. There are problems with scuffing here, but they occur less frequently than in the predecessor. The culprit is overheating, driving with a cold engine, poor gasoline or oil. The expansion tank and coolant pipes often crack and leak. The injection pump system and fuel pumps in the tank cause a lot of trouble. The hot part of the turbine often cracks, ignition coils fail, and the pump malfunctions.
