I Changed the pcv valve today, but with no help from my chilton's digital manual.  The picture did not show where it was for my 16v.  Oh they had a picture of it , but it did not look like my engine.  So I went to the autozone online manual, and sure enough, it had the same picture.   So I almost gave up on it, but as I was about to close out the window, I noticed the directions were diffrent.  It started out by saying to remove the throttle shield first.  I did that, and WHOOP THERE IT IS, right where it shoud be.
