Weird whistle...
Just a little background also:
I recently replaced all the power steering stuff, then a leaking water pump. The pump had leaked onto the ac stuff, and either the idler or tensioner pulley was squealing from the antifreeze that got into the bearing so I removed the ac pulley. This whistle has been there through all of this. I know a lot of LS1s whistle especially with an air lid, but this is really loud. Thanks for any help.
