Good to hear you got it figured out, but I did just go to the trouble of creating a modern art masterpiece to use as a visual aid, so I'm gonna attach it so all was not for naught:
That is actually a screen grab from the TSB for replacing the PCV valve on the Pentastar back in 2011, with some additional content courtesy of yours truly. Just in case anyone else runs across this thread and wonders what all that mess is, here's what the numbers are pointing to:
1. Make-up line (aka Fresh Air line) - Allows the engine to replace the dirty air it is removing from crankcase (which is pulled out through the PCV valve[2] and into the intake plenum[6] via the PCV line[3]). The vacuum left behind in the crankcase is filled in by clean air drawn in from air intake box (or air intake tube[4] in the case of aftermarket CAIs).
2. PCV Valve - This is the traffic cop of the PCV side of the CCV system! It will allow blow-by gasses to be pulled out of the crankcase (or blown out if engine operating at maximum TQ output, i.e. WOT & redline) and into the intake plenum ( via the PCV line[3]) to be mixed and eventually burned with the incoming air charge. It polices this flow of gases by opening and closing only as much as necessary according to the amount of vacuum present on the intake side of the valve
*, with the help of an embedded spring to keep it closed at low or no vacuum operation.
3. PCV line - Allows the engine to remove the dirty air from the crankcase by providing a path for those blow-by gases to flow through once they exit the PCV valve. It delivers these gases to the intake plenum[6] so that they can be mixed up with the incoming air charge and burned at ignition.
When installing a Catch Can, the PCV line is the line that it needs to be spliced into.
4. Air Intake Tube - Carries the incoming air charge from the air filter box (or bare air filter element if CAI) to the intake plenum[6] to be mixed with blow-by gases from the crankcase which are pulled in through the PCV line [3] via the PCV valve[2].
Stock Pentastars in OE configuration will have a rubber intake tube with a built in noise baffle attached to the outside of it at the point it bends to go back toward the Throttle Body[5]. The noise baffle is made of black plastic and is removed with the stock intake tube when an aftermarket CAI is installed (unless stock intake tube is left on, in which case the baffle does as well).
NOTE 1: The absence of this noise baffle on an Pentastar with a CAI installed is a big part of why the WOT sound is so different with the CAI versus stock air intake tube/filter box setup.
NOTE 2: The make-up line[1] will connect at the air filter box in a stock or OE setup, but it will usually connect directly to the air intake tube (just upstream of the air filter element) on an aftermarket CAI setup.
5. Throttle Body - This meters the amount of air coming into the engine to be burned. But for our purposes, just think of it as the connection point between the air intake tube[4] and intake plenum[6], but more importantly
it can be used to judge the efficacy of your Catch Can mod. For that, you will need to remove the TB at the same time as you install the CC and clean the backside of it with a proper solvent (not all can be used on an electronic part, so read the label!!). Basically, just remove any oily sludgy or caked-on deposits that have accumulated on the back side of the TB, and then just reinstall it once you're done.
To check whether or not your CC is doing its job, periodically remove the TB (~10-15K miles) and inspect the same surface previously cleaned. It should remain relatively clean and free of any new oily deposits or sludge build-up. If it does, that is a good indicator that the CC is doing its job - keeping microscopic oil droplets from making it into the intake plenum[6] where they tend to sludge up every surface they come into contact with.
However, if any new sludge deposits or oily films are noticed, then that is a good indication that your CC is NOT doing what it is supposed to do. Whether or not it is malfunctioning or just being overwhelmed (undersized, not emptied often enough, etc.), you can't know for sure without some investigation. But either way, it is effectively a broken part and needs to be "fixed" accordingly.
6. Intake Plenum (aka Upper Intake) - This is that big, ugly, black plastic thing sitting on top of your engine...no, not THAT ugly black plastic thing, that is the engine cover. Pull that thing off, and then you will see the Intake Plenum below it. This is the center piece for this whole perverted ballet we've been talking about here.
The inside of the intake plenum is where the clean, filtered air charge coming in from the intake tube[4], through the Throttle Body[5], where it meets up with the dirty, polluted air coming from the engine crankcase. As those two dance around each other and gyrate their hips in a perverted fashion, they are forced to mixed together before being sent down the intake runners into the combustion chambers to be mixed with the fuel and burned.
However, before leaving the dance floor, those nasty blow-by gases from the crankcase will leave behind most of their oil-droplet passengers on the inside surface of the intake plenum. Eventually that will start to form an oily sludge that gets baked into a nasty goop over time that is not good for anything except staining whatever it touches and resisting all but the most aggressive of attempts at being removed or cleaned off.
And THAT is precisely the sort of thing your new Catch Can can help reduce or even prevent, and thus one of the reasons that a CC should be considered for the Pentastar when making a list of mods to perform in search of more performance/longevity.

There, now you know everything I know about this subject. I can now lay my weary head down and sleep...sleep the sleep of the vindicated...I told my ole lady learning all that stuff way back when we had my 2011 wasn't going to be a waste of time, and now I've just proven it! Please use this knowledge for good instead of evil.

* - This is true except for when engine is operating at or near its maximum TQ output, i.e. WOT & redline. At that point, the PCV valve[2] can stop responding to the vacuum on intake side of PCV line[3] and be forced fully open by the pressure on crankcase side of PCV valve. Normal operation returns as engine TQ output falls below max lb/ft numbers.
