So I snapped off the little nipple on my intake tube that looks like is the inlet for the PCV system. Can I just plug the intake tube and run breathers on the inlet and outlet for the PCV system? Does our ventilation system have a built in, or in-line, PCV valve? And where is the outlet vent for our PCV system? Just got this car and have not learned any of the ins and outs of the motor yet, Is this going to throw any emmisions codes? I've run breathers on many cars without any issues.
OR
Should I just get another OEM intake tube/air box piece?
OR
Should I just go ahead and get an aftermarket intake tube and which ones would you recommend? I'm completely stock, I think.

It shouldn't throw any codes.

The replacement piece is about $90 through a dealer.

Dejon makes a decent one, as does Werks, as does DDM, and there's always GMPP. Replacing that plastic nipple with a metal nipple is expensive, and that's about all you are doing with any of these pieces.
Of course, the plastic OEM part will likely break again.
You don't need a tune to run any of the one's I mentioned. All they are is noise makers.
Really? I can't believe that there are no gains to be had by freeing up the flow a little bit. Is the OEM intake that good or do the aftermarket ones just suck?
VERY common problem, you can just glue it back on, or follow some (maybe) more permanent fixes. Not worth replacing the intake unless you really want to do so for cosmetic reasons.

The OEM one is just that good. In fact many aftermarket ones actually screw with the ECM (due to poor airflow past the MAF).

Maybe I will just plug the hole and run a catch can to breather set up. Can our PVC valve be removed? I know on my Mustang I had to actually cut it out of the valve cover.
Well I'm thinking more along the lines of venting the crankcase to the atmosphere so the catch can would just be protection against any oil drippage from the breather filters.
Check valve? In any case, mine's been detached from the intake, and a breather filter plugged into the end instead.
I didn't use one like 07Boss pictured because I used one like this:
Because it fit into the check valve perfectly. I sprayed mine matte black so you can hardly tell it's not supposed to be there.
Oh, and I get almost nothing coming out of there.
I have disconnected the other line at the turbo for ****s and giggles, and found some oil, but not a ridiculous amount. Seems I get more oil from the line to the turbo than I do the line to the intake, and in any case, never enough to make a noticeable difference in oil levels after a 10,000 km oil change.

This is as would be expected. Read that post link again, the broken valve end is an INPUT to the engine - the air intake has an angle to help force air into it. The pipe down to the turbo is the outlet and even though the valve cover has baffles, you could get some oil coming out of it.

Input? Isn't there a PCV on that line on the other end? And if so, wouldn't it also be an output for pressure?
I check that lower line once or twice a year, whenever I do an oil change, and I've never found more than a few mm (maybe a teaspoon or so).
And out of the top line, nothing ever but a slightly brown film which I'm assuming is finely atomized oil that's been deposited by vapor/air.

Not sure why you have trouble believing this. If an engine can suck, say 400 cfm at red line, and the stock intake flows 500 cfm, what possible benefit do you think will come from installing a different intake that has a flow limit of 700 cfm, or for that matter 2000 cfm?
Whataver the engine can suck is the top limit. All an intake has to do is be able to supply that without any restriction. The GXP intake does that.
