Engine Overview and Common Failures
The weight of the G4FJ engine is 106.3 kg. The engine number G4FJ is located at the front, at the junction with the gearbox. In the early years of production, there were often problems with spark plugs breaking and leaving scratches, as well as pistons cracking due to detonation, even at mileage of only 40-50 thousand km. One of the most common complaints on forums is the low turbine lifespan, often causing oil consumption from an early stage. Replacing the unit can be very expensive. In terms of oil consumption, the aluminum block with an open cooling jacket and thin-walled liners quickly wear out, leading to increased oil consumption. Other issues reported by owners of vehicles with this engine include low chain lifespan, frequent lubricant leaks, and unstable engine performance due to throttle contamination or carbon deposits on the valves.
