I recently bought a 2010 Mazda CX-7. In the time of purchase, 95,000 kilometres had been done by it. The turbo engine failed in the pipe between the engine and the turbo because of buildup. As we didn’t get the car serviced within 10,000 21, we’ve been told by Mazda it’s our fault. If the oil light not have notified us that there was an oil issue? – Norm
In most vehicles, the “oil light” will be brought to the driver’s attention when their vehicle travels around a corner.
The oil sloshes to one side. The result will be, if the oil level is low. The oil pressure plunges along with the oil light will flash, indicating to the driver to stop and check the oil level of the vehicle.
The turbocharger of your Mazda has turbine and a rotating shaft that rates up requiring an uninterrupted stream of oil. The feed pipe the trader is currently speaking to is the sole source of oil of the turbocharger.
In your case, I feel the feed pipe became plugged by the sludge buildup limiting oil flow. The turbocharger overheated, damaging the bushings, resulting in a failure.
Turbochargers will fail with pieces and bits of metal. As the absence of oil was because of restriction and not a minimal condition the oil light wouldn’t have come on in this situation.
