Disadvantages of the Hyundai G6DM engine
- The main problem with GDi units is the formation of carbon deposits on intake valves;
- The aluminum motor is afraid of overheating, so keep an eye on its cooling system;
- It is not yet clear how long the timing chains will last, the resource was low on the predecessor;
- Hydraulic lifters are not provided here and valve clearances will have to be adjusted.
