Disadvantages of the Alfa Romeo 937A1000 engine
The engine has all the issues associated with direct injection engines, including valve soot;
Additionally, because of the piston group’s quick wear, an oil burner is frequently found here;
The phase regulator and oil pump will not last long if the motor is not lubricated;
The camshaft cams’ resource is greatly diminished by the system’s drop in oil pressure;
Keep an eye on the balancer belt’s condition; if it breaks, it falls beneath the timing belt.
