Disadvantages of the Hyundai G8BE engine

  • This is a very reliable engine and owners often complain only about fuel consumption.
  • The main problems are associated with the rapid formation of carbon deposits on the intake valves.
  • The main cause of thrust failures is the failure of the fuel pump in the tank.
  • After 200 thousand km, timing chains are often pulled out and usually with phase shifters.
  • It is also worth noting the high price and a small selection of spare parts for this motor.
