Disadvantages of the B4164S engine
There isn’t even a phase regulator in this version of the straightforward and dependable gasoline engine.
Lubricant consumption as a result of clogged crankcase ventilation is the main issue.
The valves bend when the timing belt breaks because it frequently travels less than the recommended 90,000 kilometers.
A broken ribbed belt and the water pump’s backlash can also harm it.
A damaged camshaft position sensor rotor can occasionally be the reason for engine failure.
