Shortcomings, breakdowns and problems of AX
The main problems are leaks from the seals of the nozzles and the tandem pump
Another aluminum block without sleeves is very afraid of bad diesel fuel and is prone to scuffing
Often, the oil system heat exchanger flows here and the lubricant enters the antifreeze
Closer to 200 km of run, rockers or camshaft cams may already wear out
This unit still has a lot of weaknesses, but they are typical for modern diesel engines.
