Disadvantages of the Alfa Romeo AR32301 engine
The wear of the cylinder walls and the ensuing oil burn are the engine’s primary issues;
The engine’s sensors frequently malfunction, particularly the mass air flow sensor and crankshaft position; the balancer belt is short-lived and may fall under the timing belt if it breaks; the phase regulator, oil pump, and VLIM system in the intake are the weak points here; camshaft cams are also erased due to wedging of hydraulic lifters.
