The weight of the M102 engine according to the catalog is 165 kg. The engine number M102 can be found on the cylinder block. The most well-known problem with this engine is camshaft wear at a mileage of 150,000 km. The second most common issue is excessive oil consumption, often caused by oil control rings. Vibrations and noises under the hood usually disappear when the engine mounts are replaced. The timing chain in this engine has very little play, and the new dual-row chain only lasts slightly longer. Before 1984, there were no hydraulic lifters, and the valves needed adjustment every 10,000 km.
