The weight of the 3B21T engine is 69 kg (excluding attachments). The engine number 3B21T is located on the cylinder block. This power unit is quite reliable for a turbo motor, but its fuel consumption is quite high. The most important thing is to monitor the cooling system, as overheating can immediately lead to cylinder head damage. Due to hardened seal rings, lubrication often leaks into spark plug wells. Around 150,000 km mileage, the turbine or timing chain may require attention. Since there are no hydraulic compensators, the valves need to be adjusted every 100,000 km.
