Need help with noise
 
Hey,
You guys might have seen my post about replacing my timing belt and all components. Anyway, I have a noise coming from what sounds like the TB area. I made sure everything was tight. I checked under the TB cover and made sure the belt was tracking right and it looks like it is. Heres a video, thanks

Can't tell much from the video, but sounds like a rattle in either the TB or serpentine belt area. You sure everything got tightened down properly? Maybe the serpentine tensioner?

Im suspecting the tensioner, but it is tight. The TB parts are tight. Im thinking maybe one of the pulleys for the serpentine belt but Im not sure

The video sounds like an engine running. Is the noise you're concerned about an occasional clacking? I thought I might have heard that.

If it is, then I think the next step is to take the serpentine belt off and listen again. It'll run with the timing cover off, so you can watch the timing belt and listen, but it wouldn't be easy for anything in that system to make any occasional noise, unless the tensioner lost all its tension.

if not the clacking, please do describe the noise. If you think you have a whirr, rumble, growl, chatter, etc.

+1, Take the serpentine belt off and see if you hear the noise then. Sounds like it only happens when you rev the motor.
