Disadvantages of the Geely JLC-4G18 engine
The motor is largely praised on specialized forums, and no flaws have yet been discovered;
This timing chain has a lengthy lifespan and covers distances exceeding 150,000 kilometers;
There are no hydraulic lifters, and valve clearances must be changed every 100,000 kilometers. After 200,000 kilometers, oil scraper rings frequently lie down and an oil burn develops.
