Since 2008, the Chinese plant has been producing the 1.5-liter Great Wall GW4G15 engine, which powers well-known models like the Hover M2, M4, and comparable Haval H1. In essence, this power unit was a licensed replica of the Toyota 1NZ-FE engine from Japan.

Toyota engine clones: GW4G15, GW4G15B, GW4G15K, and GW491QE.

Disadvantages of the Great Wall GW4G15 engine
Oil consumption is the most well-known issue with engines in this family;
The primary cause is either rings or inadequate crankcase ventilation;
Nearer 100,000 kilometers, a phase shifter and timing chain replacement are frequently required;
The engine mounts, turbine valve, and ignition system are the unit’s weak points;
Every 90,000 kilometers, valve clearances must be adjusted by choosing tappets.
