Disadvantages of the Alfa Romeo AR32104 engine
Here, the oil pump fails quickly due to improper oil selection;
The resource of hydraulic lifters is diminished when the oil pump’s performance declines;
The camshaft cams then deteriorate as a result of the hydraulic lifters wedging;
A phase regulator, an electronic throttle, and a crankcase ventilation valve are the weak points in a strong oil burner that is frequently discovered on long runs as a result of stuck rings.
