Disadvantages of the XU10J2 engine
Candles and ignition coils quickly deteriorate due to poor fuel; the idle speed controller is typically the cause of the floating engine speed;
Keep an eye on the timing belt’s condition; if it is declared to be 120,000 km, it might not pass;
Regular oil leaks occur from beneath the crankshaft oil seal and valve cover;
It is challenging to find a replacement for the plastic intake manifold, which frequently cracks;
Unstable operation in frost and freezing crankcase ventilation is discussed on specialized forums; you will need to adjust the valves because there are no hydraulic lifters.
