Disadvantages of the Geely JLH-4G20TD engine
This engine is susceptible to carbon deposits on the valves, just like all direct injection units; no significant complaints about it were found on specialized forums;
Some owners report leaks in the crankshaft seals and fogging in the crankcase ventilation. It’s crucial to keep an eye on the timing belt’s condition because if it breaks, the valves will bend.
