Engine Mercedes M113 E50

The M113 E50 engine is an unusually lightweight, compact engine (unlike its predecessor M119) was a continuation of the line of three-valve M112 engines. The engineers added two more to the six cylinders and got the M113. Due to its compactness, it was installed on all rear- and all-wheel drive Mercedes models. Each cylinder has three valves (two intake and one exhaust), and in the M113 engine, the area of ​​the exhaust valve is 30% less than the total area of ​​the two exhaust valves in its predecessor, in addition, it has less weight (the rod is filled with sodium).

Disadvantages of the M113 E50 engine

  • The main problem of the power units of this family is the huge oil consumption.
  • The main cause of the oil burner is usually hardened valve stem seals.
  • Due to contamination of the crankcase ventilation, the lubricant presses through gaskets or seals.
  • Also, the source of leaks is often the oil filter housing and heat exchanger.
  • Another branded engine failure is the destruction of the crankshaft pulley.
