Disadvantages of the Hyundai G6BV engine

  • The intake here is equipped with dampers, and their bolts are unscrewed and fall into the cylinders;
  • Still periodically there is a jump of the timing belt due to the wedge of the hydraulic tensioner;
  • Quite a few complaints are related to the oil burner, but this is after 200,000 km;
  • The main reason for floating engine speeds is contamination of the throttle, idle speed controller or injectors;
  • Weak points include sensors, hydraulic lifters and high-voltage wires.
