Disadvantages of the FUJA/FUJB engine
Candles and their coils break easily here, and the engine cannot handle poor fuel;
Low-quality gasoline causes the fuel pump filter to clog and malfunction;
The timing belt is supposed to last 120,000 kilometers, but it frequently fails much sooner;
Additionally, the power unit’s pillows and thermostat have a limited resource;
Since there are no hydraulic lifters, valves must be adjusted every 100,000 kilometers.
