Disadvantages of the Hyundai G4FT engine

  • The main problem of hybrids is not reliability, but the lack of service stations or spare parts;
  • Let’s look at the resource of the timing chain, its predecessor had a rather modest;
  • The catalytic converter is located close to the cylinder block and scuffing is quite possible here;
  • Apparently it doesn’t have hydraulic lifters and the valve clearance needs to be adjusted.
