Where is the PCV valve located anyways? I just bought one from Autozone to replace my original for my 87' Grand National and I was wondering how I replace it! Thanks for any suggestions.

Anyway, the PCV valve is kind of hard to see... follow the big vacuum line from the top of the throttle body around the pass. side of the manifold. It does a 90 degree bend and goes down to a grommet in the base of the intake manifold in between the runners.
Hopefully you bought the AC/Delco part. (CV893C) There is a Fram number for this, but I think most find that the AC part is the only one that seals well under boost.
