What goes here ? Need help ASAP please.
What goes here ? Need help ASAP please. 
This is on the back of the drivers side valve cover; there is an open hole on the top and an open tube. My guess is that they are supposed to be connected.
What is the name of the part that goes here? Is it something I can pick up at a parts store for a quick fix or a is it a dealer only part?
I’m guessing it was left off or never reconnected after a rocker arm install and why my car has been running like crap at idle since. And yes, tremble before my mad wicked MS Paint skills.
EDIT - MODS: Not sure where to post this so please move if need be.
