Disadvantages of the B5202S engine
There is no electronic choke or phase control in this highly dependable version of the motor.
The most well-known issue is the oil burner’s clogged crankcase ventilation;
The timing belt might not travel the full 120,000 kilometers, and the valves will bend if it breaks;
Here, fuel injectors and ignition system components frequently need maintenance;
The engine’s thermostat, fuel pump, upper support, and pump are also weak points.
