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.
