The weight of the RF engine is 187 kg (with attachments). The RF engine number is located at the junction of the block and the cylinder head. These are simple and reliable diesel engines, most of their problems come from aging. Leaks are often discussed on forums, with oil sweating through the cylinder head gasket being a common issue. The timing belt should be replaced according to the schedule, either every 60,000 km or in case of valve interference. After 200-250 thousand km, cracks around the pre-chambers are often found. There are no hydraulic compensators, so don't forget to adjust the valves every 100,000 km.
