Disadvantages of the HYDB engine
- The main problems due to contamination of the PCV valve of the crankcase ventilation system;
- From the howl of the motor and leaks from the camshaft seals, replacing its membrane helps;
- If you pull with a replacement, the oil will ooze onto the timing belt, reducing its life;
- Due to low-quality fuel, spark plugs, coils and a gasoline pump quickly fail;
- Some owners had to change the turbine at a run of about 100,000 km.
