Disadvantages of the Alfa Romeo 839A6000 engine

  • This is a simple and reliable motor, and many of its problems are caused by poor wiring.
  • Also, a lot of trouble here delivers a booster pump, a mass air flow sensor and an EGR valve.
  • Strong engine vibrations usually indicate that one of the injectors has begun to pour.
  • The turbine runs well, often only the system for changing its geometry fails.
  • Another weak point of the diesel engine is the not very durable oil pump chain.
