The weight of the 6G71 engine according to the catalog is 190 kg. The engine number 6G71 is located at the junction of the engine and the gearbox. Engines from the early years of production were problematic and caused many issues. However, the quality improved over time and owners often complained only about oil consumption. The main thing is not to overlook the lubrication level, as worn bearings are not uncommon. The main cause of erratic revs is throttle or EGR valve contamination. Weak points include an unreliable ignition system and hydraulic lifters.
