Disadvantages of the Mitsubishi 4N14 engine

  • At the moment, this diesel engine has shown itself only on the good side, except perhaps for a strong rattling;
  • During the burning of the particulate filter, a certain amount of diesel fuel enters the oil;
  • Piezo injectors do not like bad fuel and can fail even before 100,000 km;
  • The EGR valve clogs up pretty quickly, and the intake flaps still get stuck from soot;
  • Once every 45,000 km, the thermal clearances of the valves require adjustment with the removal of the injectors.
