Disadvantages of the Geely JLC-4G18 engine
- On specialized forums, the motor is mostly praised and no weaknesses have yet been found;
- The timing chain here serves quite a long time and stretches on runs of more than 150,000 km;
- After 200,000 km, oil scraper rings often lie down and an oil burn appears;
- There are no hydraulic lifters and valve clearances need to be adjusted every 100,000 km.
