Disadvantages of the Honda B18B engine
- This series of motors is very reliable and has virtually no characteristic weaknesses;
- Against the general background, only a thermostat and a water pump have a limited resource;
- After 200,000 km of run, the risk of sudden penetration of the cylinder head gasket increases;
- The timing belt is designed for 90,000 km, and if it breaks, the valves can bend here;
- Every 40,000 km, valve adjustment is required, since there are no hydraulic lifters.
