Disadvantages of the Honda B18B engine
This line of motors has almost no distinguishing flaws and is incredibly dependable;
In contrast, only a water pump and a thermostat have limited resources;
The possibility of the cylinder head gasket suddenly penetrating increases after 200,000 kilometers of operation;
The valves may bend here if the timing belt, which is intended to last 90,000 kilometers, breaks;
Since there are no hydraulic lifters, valve adjustment is necessary every 40,000 kilometers.
