Disadvantages of the B5254T2 engine
- The main problems here are caused by regular failures in the phase control system;
- Also on specialized forums they often complain about oil consumption due to clogged crankcase ventilation;
- Even in this engine, the front camshaft oil seals constantly leak;
- The timing belt does not always run the scheduled 120,000 km, and when it breaks, the valves bend;
- The weak points of the motor include a water pump, thermostat, fuel pump and engine mounts.
