Disadvantages of the Great Wall GW4G15K engine
- A well-known problem of power units of this family is oil consumption.
- About 100,000 km in the engines of this series, the timing chain is extended and requires replacement.
- Also weak points here include the ignition system, turbine valve and engine mounts.
- Valve clearance must be adjusted by selecting pushers every 90 thousand km.
