Terrible Squealing Noise

[FastA$$89Vert]

Theres a loud sqealing noise coming from the driver front of the car. It gets louded with higher RPM, I thought it was the belt, so I sprayed some dressing on it, but it didnt help at all.

What else could this be?

Loose pulley?

I would check all the pulleys. also have u checked for and vacum leaks that could casue a whistle??

Have you checked your Power Steering fluid?

 

[srothfuss]

Check all of the underhood fluids for an indication of any major issues. Next remove the belt and spin the pullies by hand. Chances are one of the pullies is siezed....

 

[FastA$$89Vert]

all fluids are good

all pullies spinning freely

belt nice and snug

tensioner is quiet


but the belt is riding a little left of what it used to, its also wobbling a little when it runs...Im thinking loose pulley, maybe alternator.

 

[HISSIN50]

so which pulley is wobbling?

Did you push in and pull out on the pulleys longitudinally?

Good luck.

 

[FastA$$89Vert]

yea, none of them feel loose at all, I dont see why its wobbling.

 

[srothfuss]

Has the tensioner bolt backed out at all?

 

[FastA$$89Vert]

Tensioner still looks good.

Im gonna throw a new belt on tomorrow and see if it helps, but the belt is getting a little torn from rubbing the alternator pulley wrong.

 

[HISSIN50]

A wobbling pulley has to have slop in the axis somewhere.
A tearing belt suggests poor alignment of the pulleys. I would want to make sure no accessories are cocked. This can be very hard to eyeball. Dont forget to make sure that the accessories themelves are tight (check the bolts and ferrules in the bosses).

Have you done any work recently that involved the accessories?

Good luck.

I just rebuilt the motor after having it apart for a year, switched cams, got the heads ported, etc.

But it developed this squeek right before I took it apart when it blew the head gasket.

i recently changed my old stock dist to a new billet one. every since then i have had this damnable belt squealing. i hit all the pullety shafts with wd40 and it is still squealing. so i took a piece of conduit and held it against each accessory while the car was running and finalyl located the source. the power steering pulley. no wobbling or off center motion, belt is fine etc etc. i hit the power steering shaft and pullet front and back with wd40 and it is still squealing. it's driving me freaking nuts. it totally ruins the sweet exhaust tune i have grown to love. the power steering pump hasn't lost any fluid and doesn't show any signs of leakeage anywhere so i guess i have one of those sneeky little inexplicable mechanical gremlins in my car. dammit.
