2003 Cavalier LS Sport with the 2.2L Ecotec. 93k miles, it was a highway commuter so it's in good shape. Meticulously maintained.

Anyways, I went to SeaFoam it and I've always used the PCV valve hose so I went to remove said hose and use some extra to SF it. Well, I went to take it off (Used vice grips and slid down the clips) and the nipple in the upper intake mani is broken off! What should I do about this? Idle doesn't surge or anything and it slightly varies if you take the revs up in neutral, but I figured it was because the engine was cold.

What kind of part would I need to replace or is there a way I could do a valve cover breather and just block off this hole? I haven't taken it apart because I'm not sure if this is even a problem. Here's a picture circling the pieces I'm mentioning.

you COULD do a breather. Or just replace the intake with aftermarket. Or go to a junk yard and find a new/used one.
BTW thats NOT the intake manifold....lol

drill it out if you have to and epoxy the hose into the hole.

Or superglue it, like I did. Mine snapped off the very first time I took off the intake box. Just make sure you do it while the box is off of the TB, because you don't want any of those fumes messing anything up. Once you have the nipple aligned the right way, just superglue the heck out of it. Well, just a little at first to get it to stay where it is supposed to be, then a lot more glue. But let it dry for at least 6 hours, because with that much superglue, it takes a long time for it to dry all the way through.
