Disadvantages of the Alfa Romeo AR32201 engine

  • This unit needs a specific oil or its oil pump will not last long;
  • Due to a decrease in the performance of the oil pump, the resource of hydraulic lifters decreases;
  • And from the wedging of the hydraulic lifters, the camshaft cams quickly wear out;
  • On long runs, an oil burner often appears due to the fault of stuck piston rings;
  • The weak points of the motor include an electronic throttle, a phase regulator and a crankcase ventilation valve.
