Who is squealing.the engine, alternator, tensioner, & wi
Well, I read the posts on engine squealing, but I would like some confirmation.
I just finished the dreaded upper & lower intake manifold replacement and all went fine until a day later something under the hood started squealing in a loud, high pitched shrill noise. At this point, my wife is squealing at me because of this squeal under the hood. So, I need to silence both squeals. The symptoms:
1. When we did the manifold replacement, we left off an O ring from the PCV valve. Would this cause the problem?
2. The squeal doesnt occur until I drive a few miles.
3. The squeal occurs regardless of the weather.
4. Performed the 'ear to screw driver' test on accessory pieces and determined all accessory pieces are about the same loudness.
Any ideas?

After reading the post that 'mkaake' pointed me to, I went out and got the car idling. I then pulled the oil cap off, and lo and behold, the squealing stopped! I put the oil cap back on and the squealing came back immediately. I again pulled the oil cap off and the squealing stopped immediately...put the oil cap back on and the squealing started immediately.
So is my first step getting the O ring back on the PCV valve? If not, what should be the first thing I do? Given I put the O ring back on first, what else do I need to do after this?
Mkaake, thanks for pointing me to the post!

As we all thought, it was the absence of the O-ring which caused the squeal. To clarify, it was not the large O ring near the top of the PCV valve which was missing, but the smaller O ring near the bottom of the PCV valve which was missing. This ring is about the size of a nickel and fits around the shaft of the PCV, and when I looked at it, quite frankly I didnt think the inclusion of it would matter. Lo and behold, the inclusion of this O ring does matter and by putting it back on, the squealing is gone!
Thanks to all who helped me with this problem. I saved time, money, and learned something in the process.
