Mystery Air Box Bung? Where does this go to???

[Overlord475]

I was replacing my IAC valve last week and noticed that one of the bungs on my pre-throttle body air mixer box is missing a hose.

Where does this line go to?

Does anyone have a hose diagram for the 02 Liberty?

that goes to the pcv valve, idk about the 02-04 model years but on the 05-07 its on the engine oil fill neck, maybe someone will post a pic of theirs for you later

PCV is in the same place on the 02-04s. Your hose fell off at some point and it's sucking unfiltered air in from the engine bay (and your crankcase isn't being ventilated.)

Aaaaah, that's not very important p:

The PCV is correctly routed to a bung post throttle body on the diverside of the air box.

The mystery bung that I'm missing a hose to is on the passenger side of the air box.

Second guesses?

If I remember right that is unused in the 02-03 models. Mine is bone stock and my manual shows nothing going to it.

On my Liberty, that breather element in the airbox goes into a tee with one end going to the pcv and the other to the breather element, main part comes from the drivers side valve cover. Mine broke as well

I have been having trouble trying to fix that hose/hoses, were you able to? I don't know the part number or how to buy it? Junkyard maybe? Thanks!
