Disadvantages of the Hyundai G3LC engine
They typically complain about the unit’s loud operation and excessive vibration on specialized forums;
Additionally, this motor cannot withstand overheating, tan gaskets, or significant leaks;
The timing chain is stretched and requires replacement for active owners even after 100,000 kilometers;
An oil burner is frequently discovered on the same run because of rings; short-lived engine mounts and an adsorber valve are also weaknesses in this situation.
