Disadvantages, breakdowns and problems of the internal combustion engine B5252S
This unit does not have a phase regulator and an electronic choke and is therefore reliable
The most famous problem is the oil burner due to clogged crankcase ventilation.
It is important to monitor the condition of the timing belt, since when a valve breaks, it usually bends
Quite often, the rear crankshaft oil seal and the oil pump gasket are leaking here.
The engine mounts, water pump and fuel pump also have a modest resource here.
