Disadvantages, breakdowns and problems of CGWB
The main problem of all units of this series is increased oil consumption.
The reason for the oil burner is scuffing due to the ingress of catalyst crumbs into the cylinders
Also, the chain is cracking here, since there are no check valves for the cylinder head oil channels
Another culprit in the noise of the timing chains is the heavy wear of the hydraulic tensioners.
Other weaknesses of the internal combustion engine: pump, injection pump, and muffler corrugations often burn out
