Disadvantages of the Hyundai G6DK engine
- The main problem of the motors of this series is the progressive consumption of lubricant;
- The reason for the oil burn here is the rapid coking and occurrence of piston rings;
- This is a hot V6 unit, so keep your cooling system clean;
- After 200 thousand kilometers, stretched timing chains usually require attention;
- The engine does not have hydraulic lifters, do not forget about periodic valve adjustment.
