Disadvantages of the EYDC engine

  • On the old firmware, the motor power drops sharply when the air conditioner is turned on;
  • The timing belt and its bypass roller have a low resource, and when the valve breaks, it bends;
  • In case of traction failures, it is worth starting the search for causes with a gasoline pump and its two filters;
  • Take care of the aluminum engine pan, it hangs low and does not hold a blow at all;
  • There are no hydraulic compensators, you will have to adjust the thermal clearances of the valves yourself.
