Disadvantages of the Great Wall GW4G15K engine
Oil consumption is a well-known issue with this family of power units.
The timing chain in these engines needs to be replaced after about 100,000 kilometers.
The engine mounts, turbine valve, and ignition system are additional weak points.
Every ninety thousand kilometers, pushers must be chosen to adjust valve clearance.
