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.
