Disadvantages of the Hyundai G6DC engine
- On specialized forums, the most complaining about the progressive consumption of lubricant;
- The reason for the oil burn here is usually the rapid occurrence of oil scraper rings;
- The aluminum engine is very afraid of overheating, so keep an eye on the cooling system;
- At first, there were many complaints about the timing resource, especially the hydraulic tensioner;
- Valve clearances need to be adjusted, as hydraulic lifters are not provided.
