Disadvantages of the B5254T2 engine
The phase control system’s frequent malfunctions are the primary cause of these issues;
Additionally, they frequently complain about oil consumption on specialized forums as a result of clogged crankcase ventilation;
The front camshaft oil seals in this engine are continuously leaking;
The water pump, thermostat, fuel pump, and engine mounts are among the motor’s weak points. The timing belt does not always travel the planned 120,000 km, and when it breaks, the valves bend.
