Disadvantages of the HYDA engine

  • The most common concern here is the crankcase ventilation system, or rather the PCV valve;
  • When the valve is dirty, the engine howls and oil presses through the camshaft seals;
  • If grease regularly gets on the belt, its resource drops to 60 – 80 thousand km;
  • Bad fuel quickly affects the condition of the candles, coils and fuel pump;
  • The turbine runs differently for everyone, many change it on a run of 100 – 150 thousand km.
