Somehow I could not get rid of this sound. Help please

Friends Since I bought my 2004 model 307 1.6 XR LPG vehicle, it sounds like a gigantic in their first works. First, the timing set changed in the special service, the sound did not come after 1 month, it came again, this time it was said that it is from the crankshaft pulley, it was changed with the original one, but it is the same sound again in the special service, but 1-1.5 months later. Then, at a discounted time, I went to the Aydın authorized dealers' housekeepers, fearing (about the price) they changed the alternator (v) belt here. The sound was cut again, including 30 TL workmanship.

The friends I will go crazy, this kind of voice did not go away. Only when replacing the alternator belt in the authorized service was the belt coming out of it much longer than the original. The friend even said how the man put it on here. Right now, there are discounts, my back pads have to change, I say if I change the back because I can't trust the man's tactics.

Meanwhile, the timing set + 3lt antifreeze + they cut around 400-450 TL including labor for the back pads. What would you suggest me do?
Thanks for your help in advance.

I wonder if it makes this sound wanderer?

My brother had me in 206 too, it was due to the tension of the tension apricot, I changed it, it was cut, I wanted the first change, I changed it in the authorized service, I last gave 30 TL, I changed it in the private service .. :)

I sometimes wondered what it was doing when I changed the timing and pulley while maintaining it.

If the sticking sound is coming, the flywheel part needs to change, at least that's what happened to me, and the problem disappeared when this part changed ...

I know it is a piece that does not change easily, it should be around 800TL. It is an expensive piece you will understand, the sound coming from your vehicles is not caused by this piece. What was the broken teeth in some parts of the Volant gear, so I guess it was making noise, when I first started the car, it was a disgusting voice.

I understand, you say take the car out for sale (:

If the alternator belt tensioner is automatic or its switching is adjusted, if it is automatic, it can be made from the automatic tensioner, if not, I can also make it from its bearing ...

When I turn off the heating in my car, it comes out. It continues until the car stops. It doesn't come on my next ride. But I don't know if it's the same voice.

I didn't get it, guys, I started it yesterday when it was cold, the crank pulley was like 8 lines. But I just changed the v-belt on the crank pulley.

Also, when I put it in 2nd gear after the car starts for the first time, it looks like it will drown.
