Disadvantages, breakdowns and problems of the AJ27S internal combustion engine
The very first units came with a nikasil coating and were afraid of bad fuel
But by the end of 1999, nikasil was replaced with more reliable cast-iron sleeves.
Another weak point of the motor is the plastic timing chain guides.
The aluminum engine does not tolerate overheating, keep the radiator clean
As luck would have it, the pump is distinguished by low reliability, and pipes often burst
