Shortcomings, breakdowns and problems of RF7J
Most of the problems are caused by burnouts of the sealing washers under the nozzles.
Often the return flow of the nozzles also flows, which leads to the mixing of the lubricant with the fuel.
The main source of oil leaks are cracks in the intercooler flanges.
During the burning of the particulate filter, diesel fuel can also enter the oil here.
Other weaknesses of the internal combustion engine include: the SCV valve in the injection pump, the vacuum pump and the mass air flow sensor
