Disadvantages of the HWDA engine

  • Power units of the Duratec series are quite reliable, but do not tolerate bad fuel;
  • From low-quality gasoline, candles last very long, sometimes no more than 10,000 km;
  • Exactly for the same reason, an expensive gasoline pump often fails here;
  • In European modifications of Duratec engines with a broken timing belt, the valve bends;
  • There are no hydraulic lifters here and every 100,000 km the valve will have to be adjusted.
