Disadvantages of the B4204S engine
This version of the motor without phase control was the most straightforward and dependable in the series; on specialized forums, people frequently complain about the oil burner and clogged crankcase ventilation; the timing belt frequently serves less than the recommended 90,000 km, and when it breaks, the valves bend; a broken alternator belt is also dangerous in this situation because it typically falls under the timing belt; and hydraulic lifters can knock up to 100,000 km and cannot handle inexpensive lubricants.
