Engine Overview and Common Failures
The engine weight of the 4G19 according to the catalog is 130 kg. The engine number 4G19 is located in the front, at the junction with the gearbox. Oil consumption: The oil consumption problem for this unit starts significantly later than its counterparts in the series, but by 150,000 km, the thin oil control rings are clogged and the consumption still appears. Sometimes a simple decarbonization can help, but usually only ring replacement helps. Throttle wear: The trademark problem of fluctuating idle speed due to throttle wear in the Orion series is not as pronounced here as in older power units of this family. But restored throttle valves for such an engine are sold, which means they are needed by someone. Timing belt breakage: A common cause of engine failure is the breaking of the timing belt. According to the regulations, it serves for 90,000 km, but it can break earlier, causing valve bending. And then purchasing a used engine will be cheaper than rebuilding. Other breakdowns: Owners also complain that in extreme cold weather, the spark plugs often get flooded, ignition coils don't last long, the cooling system fan malfunctions, and the rear engine support fails. The catalyst is also frequently criticized for its short lifespan, as well as the EGR valve quickly getting clogged with dirt.
