I have a 98 ws6 and I'm getting a weird sound from my engine. First of all I bought my car at an auction-it was a police stolen recovery and was really stripped-no hood, t-tops, radio. Anyway, while it was sitting at the auction site it rained like hell for a couple of days. The engine and the interior got all wet so I don't know if the sound is because of the engine getting wet. Well, the sound i'm getting is kind of a whistling or screeching sound. I notice it sounds louder as I rev the engine so I was thinking it was one of the pullies. I'm not sure if it's rust but I do notice it sounds a lot louder on a rainy humid day and you can barely hear it when it's sunny and dry outside. I tried lubricating the pullies with some wd-40 but it still won't go away. I also noticed it got a little louder after I washed my engine with simple green and rinsed it off. I have no problems with the car but it's kind of embarrasing sometimes with that sound. Your help will be greatly appreciated.

i would check the belt first. change both the a/c and main belt.
if they are old, they get hard and scream.

I had the same thing after I got some water into the engine bay, really bad noise went away after a few days but I still get a bit of a whine now and then. Does not bother me that much.

My guess is that it is a pully. Try taking them off and looking on the underside of each pully. You might be getting a little oil on the belt from a leak or as stated above, the belts are getting dry rotted.

You might have rust on the idler pully, any visible?
Take off the belt(s) and spin it by hand to see if that's it...
