Disadvantages of the Great Wall GW4G15 engine
- The most famous problem of engines of this family is oil consumption;
- The main reason is the poor operation of the crankcase ventilation or the occurrence of rings;
- Closer to 100,000 km, it is often necessary to replace the timing chain and often with a phase shifter;
- The weak points of the unit include the ignition system, turbine valve and engine mounts;
- Valve clearances require adjustment by selecting tappets every 90,000 km.
