The weight of the JN engine assembly is 135 kg. The JN engine number is located at the junction of the block and the cylinder head. Most of the problems with this unit are related to malfunctions in the KE-Jetronic system. The fuel injection system cannot be called unreliable, it's just that few people know how to tune it properly. Hydraulic lifters here don't like cheap oil and can simply start sticking. With high mileage, oil consumption due to worn oil scraper rings can occur. Weak points also include components of the ignition system and the temperature sensor.
