PCV Valve rattling while running?
I got an 88 camaro tbi, and when its hot and cold i hear my PCV valve rattling away. Do any of yall know what that could be? I replaced it and it still does it.

They are supposed to rattle. If they don't, they are clogged up.

Yup its normal for them to rattle. Though your valve cover grommet might be hardened up and loose, and amplifying the noise. Try putting in a new grommet and see if it quiets down.
