Disadvantages of the Alfa Romeo AR32301 engine

  • The main problem of the engine is the wear of the cylinder walls and the subsequent oil burn;
  • Camshaft cams are also erased here due to wedging of hydraulic lifters;
  • Often sensors fail in the engine, especially for the mass air flow sensor and crankshaft position;
  • The balancer belt does not last long, and if it breaks, it can fall under the timing belt;
  • The weak points here include the phase regulator, the oil pump and the VLIM system in the intake.
