Disadvantages of the B4184S2 engine

  • The main thing here is to monitor the condition of the timing belt, since when it breaks, the valves bend;
  • The phase regulator valve often leaks and grease pours onto the belt, reducing its life;
  • Also, the valves bend when the ribbed belt breaks, which often gets into the timing;
  • Oil consumption occurs regularly, mainly due to clogged crankcase ventilation;
  • Another weak point of this motor is the pump and the camshaft position sensor.
