Disadvantages of the Hyundai G4CP engine

  • The main problems of the engine are associated with the low resource of the timing belt and balancer belt.
  • A break in any of these belts usually ends up with valves and pistons meeting.
  • Hydraulic lifters do not like bad oil and can knock even up to 100,000 km.
  • Often there are floating idle speeds due to throttle contamination.
  • Still here, the engine mounts serve quite a bit and the exhaust manifold often cracks.
