206 HDI engine sounds

I have a 2005 model 206 hdi car, but when I run my car one morning when there is no problem, the engine started to sound like vuuuuu. Vehicle at 130,000 km

The murmur sound may come from the exhaust (throat part).

I showed the master to the vehicle, he said the teeth of the turbo were worn, but the turbo works as efficiently as before. Then he looked at his water. Does the engine water mixed with oil have its effect?

If water is mixed with engine oil, a dangerous situation causes other problems, even if it does not affect the sound. In my opinion, do not neglect water spoils the protective feature of the oil.

Tomorrow, my first job will be to leave the car. But I got stuck in that sound, it bothers me so much. I want to find out where it came from. Let the room be built exploded exhaust like ciyo sound. We lifted the car.

If it is past, if the oil is mixed with water, have it checked.
