Disadvantages of the Hyundai G6DK engine
The primary issue with these motors is their increasing lubricant consumption;
This oil burn is caused by the piston rings and quick coking;
Keep your cooling system clean because this is a hot V6 unit;
Stretched timing chains typically need maintenance after 200,000 kilometers;
There are no hydraulic lifters in the engine, so remember to periodically adjust the valves.
