Disadvantages of the EYDB engine
- Motors of the Zetec series are very reliable, but do not like low-quality gasoline;
- Quite often here you have to change the spark plugs, sometimes every 10,000 km;
- From low-quality fuel, an expensive gasoline pump regularly fails;
- In the European version of Zetec engines, when the timing belt breaks, the valve always bends;
- On the first firmware of the motor, power dropped sharply with the inclusion of air conditioning.
