Disadvantages of the Alfa Romeo AR34102 engine
Air leaks through nozzle cracks are the main cause of these issues.
This causes the power unit to overheat in addition to causing floating engine speeds.
The motor’s belt tensioner and valve guides are additional weak points.
The turbine and crankshaft liners have a shorter lifespan when poor oils are used.
Regular oil and coolant leaks also cause a lot of problems.
