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.
