Disadvantages of the Alfa Romeo AR32104 engine

  • Due to the wrong selection of oil, the oil pump fails very quickly here;
  • A drop in the performance of the oil pump reduces the resource of hydraulic lifters;
  • Then, due to wedging of the hydraulic lifters, the camshaft cams wear out;
  • On long runs, a strong oil burner is often found due to the fault of stuck rings;
  • The weak points here include a phase regulator, an electronic throttle and a crankcase ventilation valve.
