What goes in this hole? (Front of Intake Manifold)
What goes in this hole? (Front of Intake Manifold)
Underneath the throttle body on the front of the intake manifold (in the center) there's a connector of some sort. It's just behind the top of the water pump, see in this pic:

However, I can't find it in my Haynes or factory service manuals. Can you guys tell me what that is that connects there?

That sounds reasonable... I hadn't looked where that PCV hose went to yet. I'll go make sure that makes sense and based on Compstall's post, some just delete the PCV valve and hose?
Is there any reason to remove it? I always thought they were actually one of the few good emissions control devices that didn't hurt anything...

Yup, you guys were dead-on and I hooked PCV back up. I took this thing apart 8 months ago any my memory is bad.

no, did a little search earlier and a valve cover breather will be one big vaccum leak. but you can get a filter that is enclosed to keep the oil from getting into the line, but thats it...
