Which manual did you buy? If it's not the factory GM one, after the most basic repairs, most manuals are good for table props .

The PCV valve should be in the intake manifold. Look under the hood at your emission diagram. It will show you where all the emission controls are located.

That being said, on your problem, start with the posts and links in my signature file as well as the posting guidelines on the top of the forum page. We need more information to be able to help.
