Disadvantages of the B4204S engine
- This version of the motor without phase control was the simplest and most reliable in the series;
- On specialized forums, they often complain about the oil burner and clogged crankcase ventilation is to blame;
- The timing belt often serves less than the prescribed 90,000 km, and when it breaks, the valves bend;
- A broken alternator belt is also dangerous here, as it usually falls under the timing belt;
- Hydraulic lifters do not tolerate cheap lubricants and can knock up to 100,000 km.
