Disadvantages of the Hyundai G4GR engine

  • In the early years of production, there were many problems with build quality and some components;
  • Hydraulic lifters do not tolerate poor lubrication and can knock up to 100,000 km;
  • The timing belt does not always serve the required 60 thousand km, and when it breaks, the valves bend;
  • On long runs, an oil burner is often found due to wear of rings and caps;
  • Weaknesses also include the exhaust manifold, which often cracks.
