The dry weight of the G4GC engine according to the catalog is 144 kg. The G4GC engine number is located on the right, above the gearbox. It is a very reliable power unit with a long service life and no serious drawbacks. One of its weak points could be the somewhat temperamental ignition system. There are quite a few threads on specialized forums about unstable engine performance and solutions after replacing the ignition coil or its high-voltage wires. The phase regulator. Beta series engines are quite demanding when it comes to the quality of lubrication and the timing of its replacement. Therefore, cost-cutting often leads to the failure of the phase regulator before reaching 100,000 km, and the use of excessively liquid oils over long distances can also cause bearing rotation. Timing belt failure in these engines is related to the exhaust camshaft, the manufacturer's official data indicates that its lifespan is around 90,000 kilometers. However, dealers prefer to play it safe and replace it every 60,000 km, as valve bending can occur in case of belt failure.
