Disadvantages of the B5254T3 engine
- Most often, owners on specialized forums complain about failures in the phase control system;
- Also in these engines there is oil consumption due to clogged crankcase ventilation;
- Another common engine problem is leaking front camshaft oil seals;
- The timing belt may not pass the prescribed 120,000 km, and when it breaks, the valves bend;
- After 100,000 km of run, the pump, fuel pump and engine support often require replacement.
