The engine weight of the 3A90 according to the catalog is 90 kg. The engine number 3A90 is located at the junction of the block with the gearbox. This engine has a high compression ratio and is prone to detonation from poor fuel. The thin oil control rings are worn out at around 100,000 km, resulting in oil consumption. Usually, the timing chain is replaced closer to 150,000 km, often together with the camshaft phaser. Among the weak points are the temperamental electronic throttle and the short-lived thermostat. There are no hydraulic lifters here, and the valve clearances need to be adjusted periodically.
