The weight of the B6304T2 engine according to the catalog is 190 kg. The engine number B6304T2 is located on the front cover of the engine. Owners of cars with this engine often discuss oil consumption on the forum. It is not uncommon for lubrication to leak around the timing chain cover or from under the vacuum pump. The failure of the oil separator is usually accompanied by a whistling sound under the hood. In the early years of production, the front cooling pipe leaked and flooded the generator. Another weak point of the engine is the pump block and power steering, which are seated on the same shaft.
