Tap/knocking Noise PLEASE HELP????

[Dadarkside]

Ok fellas I need some help. My car is making a tapping noise. I can tell you what it is not Its not the motor or the supercharger. Each pulley was checked first with a stethoscope and pin pointed one of the idler pulleys. It was checked when the belt was off no issues. Now to the idler pulleys they were checked and switch and still when put back on same tapping sound. Now what I can tell you is that when the idler tension was moved while the belt was on the noise stopped. Here is the video I made of the car making that noise. https://www.youtube.com/watch?v=-3g0K6slxcI

Have you tried replacing the tensioner pulley bearing?

the crazy part is the noise is not coming from that but its something i can check.

My tensioner was making a knocking noise a while back and I put a new bearing on it and blew all the gunk out of the spring and the noise went away. Before I put it back on, I shot it full of PB Blaster and blew that out too.

Ok thats a good step to take. What is so freaking confusing is that the tapping/knocking noise is coming from one of the lower pulleys and not the tensioner.

Stock lower or aftermarket?
I've read about stock lowers separating and personally seen the aftermarket lowers get loose and fly off. (Cinch1985)

Lower pulley. Crankshaft pulley...

I had a bad tensioner make that exact noise. When you look at the tensioner dose it move (bounce) the same time you hear the click/ tap.

I will check it when when i get home. the part you are talking about is the Mustang Belt Tensioner right?

 

[willis414]

Yes, It's the belt tensioner the part you loosen to get the blower belt on. Check the actual tensioner not the pulley.

When i check the tensioner what am i looking for.

Is the tab on the tensioner in the middle of the slot? If the belt is too big it could be chattering on the stop on the tensioner.

i will check this this evening.

If it had not been making that noise since i had it could it be that the its time for a new belt? Also when the car was checked and the belt tensioner was moved the noise stopped when put back in its place it made the noise again.

So back in place, it is a constant noise? No come and go, aka gremlin noise?
