PUT IN DRIVE +RASE IDILE SLITY NOISE COME ON[/QUOTE]

What is a "slity" noise?? Have you watched to make sure the clicking or tapping at idle isnt the tensioner pulley worn out and slapping around? Or the a/c kicking on and off a bunch without input?

If the noise stopped with the belt off it has to be something the belt turns.... water pump maybe a suspect possibly

 

water pump was changed . I turned by hand all the pullys,seem good.allsow
listen with a scope what to do? change all?

 

When you idled it up did you have the belt on of off?

 

the belts were on and made noise. took um off no more noise
im puzzeled

 

Watch the ac compressorand make sure it isnt some how kicking on and off. Wild chance but ya never know?

And when you used the scope was the motor running or were you just turning stuff by hand?

 

I'd start by replacing the belt. Could just be time to replace, if its slipping it will make noise under load.

 

I agree, change your belt and while you're down theer check the tentioner, might need tightened up or replaced

 

yes I did try a new belt. that was my 1 try when I scooped each pully with engine running all the same

 

Have you checked the tensioner for any play?
