Default pulley problem I think, stock pulley

I removed my underdriven pulley a few days ago and put the stock one back on. There's a weird loud noise and it sounds like it's coming from the A/C pulley. At first I thought it was an uppipe leak but I don't hear anything at the uppipe manifold flange or right near the turbo, it is definately coming from between the alternator and the AC compressor. I can also feel a bit of warm air coming up from that area, is that normal? but no air between the power steering and alternator ones.

Also I checked the crank pulley bolt and it looks like it's loose, but the pulley doesn't wobble around, regardless I will torque the bolt down again. So I think the noise is either the loose crank pulley bolt, or maybe the belts are too tight? But they were just as tight with my old pulley. There's also that warm air between the alternator and A/C pulleys.

I tightened the crank pulley bolt down, it was already fairly tight. That must have been the majority of the problem because it got much quieter. U have to listen for the noise now, before it was pretty obvious. I searched and found that someone used the stuff called belt dressing, I'll try that as well.
