Disadvantages of the Great Wall GW4G15B engine
Oil consumption is the primary issue with this turbo engine and all of the family’s engines;
Rings and inadequate crankcase ventilation are the causes of the oil burner;
The timing chain frequently needs to be changed after 100,000 kilometers, usually in conjunction with a phase shifter;
The ignition system, turbine valve, and unit supports are additional weak points; pushers must be chosen to modify the valve clearance every 90,000 kilometers.
