Disadvantages of the B5254T engine

  • This motor does not have a phase regulator or electric choke and therefore is very reliable;
  • In specialized forums, the oil burner is most often discussed due to contamination of the crankcase ventilation;
  • After 200 thousand km, the cause of oil consumption is usually turbine shaft wear;
  • According to the regulations, the timing belt is changed every 90,000 km, and when it breaks, the valves always bend;
  • Also, the engine mounts, pump, thermostat and fuel pump do not last very long.
