Sound from a Peugeot 407 Engine (Video)

Hello friends. I just joined you. It's been 2-3 months since I bought the vehicle. There is only a sound in the engine that keeps my head ticking. The sound is more like a creaking sound than a ball sound. What is odd is that the engine starts to make this sound after it is warmed, not when it is cold. First, let me state my own diagnoses.

- I don't think the pressure pad comes from the ball or the ball of the pad because the same sound is present when the clutch is pressed or not.
- I don't think it is caused by engine ears or rubbing any parts because; No sound when engine is cold starts after warming up.
- I can say that the V-belt comes from the ball, but I tried to pour powder on the belts and rollers and the same sound continues when it gets hot.

Is there a friend who can give an idea or help about this topic?
When I first bought the car, I took the car to the authorized service. I asked the master why this sound originated, loosened the belt, clenched it, did something on its own, I don't even get the sound right, there is nothing in it.

My teacher, the reason for this sound is either from the bearings or the belt. In my guess, I would appreciate if you make a video by giving gas to the vehicle.

Sir, I will shoot the video by giving the gas tomorrow, but when the gas is given, the sound stops. It just does at idle, or it comes in a way I won't hear it while giving gas.

Brother, the sound of your vehicle is probably coming from the tension bar and the idler balls next to it. There is this problem across the diesel, you have to change them. I can help with the track if you want.

Hodja, if the masters understand, I will change the source of the sound, whatever the required part is 3000 km is left for maintenance, I try to handle it while I do the maintenance. It will not look for another master

my teacher sounds like it comes from the crank pulley .. but I wasn't sure exactly ...

I have the same problem in my 307 when I was idling, and the same sound sounds, I think it is probably caused by the ball bearing.
