Engine Overview and Common Failures
The weight of the F14D3 engine according to the catalog is 115 kg. The engine number F14D3 is located at the junction of the block and the gearbox. Valve sticking. The manufacturer incorrectly selected the clearance between the sleeves and the valves, which causes their valve seats to quickly become covered in deposits and then fail to close tightly. Sometimes carbon deposits even form on the valve stems and they simply start sticking. Timing belt. According to the regulations, the timing belt should be replaced every 60,000 km, but it can break earlier. On forums, you can find many stories about the belt breaking even at 30,000 km of mileage, which in most cases leads to bent valves and very expensive repairs. Intake manifold. Another common problem with engines of this family is the rapid contamination of the intake manifold and the failure of the variable geometry system. However, if you simply disable the EGR valve, you will have to clean the manifold much less frequently. Other shortcomings. Weak points of this engine also include short-lived high-voltage wires, a strange thermostat, faulty lambda probes, constantly leaking oil gasket, as well as regular oil leaks due to contamination of the crankcase ventilation system.
