The weight of the X20D1 engine according to the catalog is 170 kg. The engine number X20D1 is located at the junction of the block and the gearbox. The most well-known problem of the engine is the oil pump wedge, which can lead to bearing failure. The catalyst has a relatively short lifespan, as its particles can get sucked into the cylinders. Valve seals and piston rings are also common causes of oil consumption. The cooling system is considered a weak point of the engine, with leaking hoses and cracked coolant reservoirs being common issues. The engine crankcase is prone to cracking, especially when the drain plug is overtightened. The timing chains tend to last a long time, but the hydraulic tensioner may give out much earlier. Hydraulic lifters are not known for their durability, and neither is the oil pressure sensor.
