The weight of the G6AU engine according to the catalog is 199 kg. The engine number G6AU is located at the joint between the engine and the gearbox. The main problems with the engine are related to the quality of assembly and its components. There are many cases described on forums of bearing insert rotation at a mileage of 50,000 km. By 100,000 km, oil consumption usually increases to 1 liter per thousand km or more. Hydraulic compensators and belt tensioner have a not very high resource. Also, there is often an issue with fluctuating RPM due to throttle, EGR, or fuel injectors contamination.
