"The turbo my car sounds like a siren for weeks, but the engine is still working properly. I have no idea what it can be."

"My car, as I said before, it moves and It is operating normally. However, you should take any precautions? Is it a lubrication problem? Because the Turbo It emits the sound-whistle like a siren?"

Response from our technical expert Luis Miguel Vitoria

Evidently, something does not work as it should. If even with the noise siren ambulance he Turbo continues to operate, it is clear that the problem is not what today kills more turbines: the rupture of one of the “Propellers” of the impeller. This is a recurring fault today more than broken and caused axes, quite often, by excess hot. Like many others, will end or yes, with Turbo out of action, but often do so quickly because its effect is similar to that get a small piece that reaches the turbine, as if the admission had gotten a washer or screw.

In any case, what arises is a unbalanced shaft turbo. And that is also what happens when the admission They get small pieces of air filter, bits rubber to stick blades thinks that the turbo works with a highly temperature and that are originating a noise. This seems to be your case as if it were any of the above reasons, the turbo would have already broken; and the only solution is to intervene as early as possible to avoid replacing Blight turbine. Otherwise, the fault will mean a higher cost.
