Disadvantages of the Hyundai G6DM engine
The development of carbon deposits on intake valves is the primary issue with GDi units;
Keep an eye on the aluminum motor’s cooling system because it fears overheating;
The duration of the timing chains is still unknown, and the previous model had limited resources;
There are no hydraulic lifters available here, so valve clearances must be changed.
