Engine Overview and Common Failures
The weight of the F4Rt engine according to the catalog is 149 kg. The engine number F4Rt is located at the junction of the block and the gearbox. The turbocharger turbine in this engine is not very reliable and normally lasts for about 150,000 km, after which radial play of the rotor often appears and it starts pushing lubricant into the exhaust. Sometimes it is lost due to leaks caused by a ruptured sealing ring of the oil supply pipe. Oil consumption often occurs after 150,000 km of mileage, with a rate of approximately 1 liter per 1000 km. Apart from the turbine, the cause may be stuck rings or hardened valve caps. Electrical problems are typical for this French power unit and are known for frequent failures. Weak points include ignition coils, lambda sensors, ECU, and crankshaft position sensor. Fluctuating idle speed is usually caused by throttle or injector contamination, but it can also be due to a breach in the sealing of numerous intake pipes. Oil leaks regularly occur here: from the valve cover, through the oil separator, from the turbocharger bypass valve, or through the seals, especially crankshaft seals.
