The weight of the 20M4F engine according to the catalog is 162.8 kg. The engine number 20M4F is located at the junction of the block and the oil pan. In the early years of production, the engine had many flaws and caused a lot of trouble. There were regular leaks of lubricant and antifreeze, and the hydraulic compensators would often get stuck. Furthermore, owners of cars with this engine complain about vibrations and noisy operation. The timing belt is designed to last for 100,000 km, but if it breaks, the valves always bend. However, the main problem of this power unit is the rare and expensive spare parts.
