The weight of the 3B20 engine is 67 kg (without attachments). The engine number 3B20 can be found on the cylinder block. For this volume, this unit is quite reliable and serves without problems up to 200,000 km. On long distances, oil consumption or timing chain stretching is often encountered. Keep an eye on the cleanliness of the cooling system, as any overheating can lead to head gasket failure. Due to hardened seals, lubrication may leak into spark plug wells. There are no hydraulic compensators, and valve clearances will need to be adjusted every 100,000 km.
