Disadvantages of the Ford MHA/MHB engine

  • This motor does not tolerate bad fuel, spark plugs, and then the coils quickly deteriorate;
  • Quite often, owners have to clean the throttle and idle valve;
  • Also, the filter mesh in the tank is regularly clogged and the fuel pump fails;
  • Sometimes the timing belt and its bypass roller do not live up to the scheduled 120,000 km;
  • Due to the lack of hydraulic lifters, it is necessary to adjust the valves every 100,000 km.
