The weight of the RF5C engine is 195 kg (including attachments). The engine number RF5C is located at the junction of the block and the cylinder head. The most well-known problem with the diesel engine is the burnout of the sealing washers under the injectors. Leakage can also occur in the injector return, causing the oil to mix with the fuel. The solenoid valves of the vacuum lines often fail in the engine. The weak points of the engine also include the SCV valve in the fuel injection pump, the vacuum pump, and the EGR valve. In versions with a diesel particulate filter, diesel fuel often enters the oil during regeneration.
