Disadvantages of the Alfa Romeo AR32310 engine
Rapid cylinder wall wear and oil burn are the unit’s defining characteristics; the camshaft cams are rapidly erased as a result of the hydraulic lifters wedging;
Sensor failures, particularly those of the mass air flow and crankshaft position sensors, are the root cause of many issues;
Keep an eye on the balancer belt’s condition; if it breaks, it falls beneath the timing belt;
The phase regulator, the oil pump, and the intake’s VLIM system are the engine’s weak points.
