Default Engine has HORRIBLE ANNOYING SQUEAK!!

Ok so I have replaced the idler pulley and the tensioner pulley on my LS1 Camaro and this squeak will NOT go away. When I replaced the serp belt it went away.. but a week later it came back (after the belt stretched out I guess) So I have got to fix it.. but what else could it be. It sounds like metal on metal type of squeak. It varies with RPM… it’s horrible!!!! I know it’s a pulley just because of how it went away when I replaced the belt. I am sick of buying parts thinking it will fix it… and then it does nothing.

What should I do?

I have had that same prob. I haven't been able to fix it permenantley even after changeing those same parts but I have found that if i crank the car and let a bar of hand soap ride on the groves of the belt for a few second the squeal will go away for a day. Before I started "soaping" my belt it seemed to squeal more after long periods of rain and belt dressing makes it WAY worse. I figure it has alot to do with my leaky power steering pump getting crap on the belt, But thats another complaint.

Alternator pully. get a shorter belt and check it out.

I chased the same noise for a week. Checked the power steering, tensioner, idler, found it to be the alternator.

I have this same problem but it seems worse after it rains or during I maybe the moister on the air gets on the belt and loosens it where do I find this bulliten on how to fix it, I alwas feel like a trashy redneck that doesnt take care of his car when I drive with it.

Well, to see if it's the ac tensioner, you can take the belt off, then douse the area with water and see if the squeaking has stopped

It's used for valve jobs (lapping the valves). Basicly it's grease with some grit in it. I get it from Napa on the west coast. I think any parts store can get it.
