Are you referring to the small nipple that the vacuum line from the TB (with the check valve) is attached to? If so, yes it is supposed to be open, but it is a very small hole and I would be very surprised if you were able to get a tight enough seal with your mouth to be able to move air through it.
I will admit that I have maybe read of one replacement of the V6 oil separator on this site; the V6 engines have not been prone to the PCV woes you have read about with some of the 4 cyl engines. The points of failure on the V6 PCV system have tended to be the white check valve, a vacuum line itself, the orifice on the oil separator being plugged, or even something as simple as a failing o-ring on the oil cap. And, are you sure that the valve cover gaskets went in OK and sealed when you replaced them?
Back to the hole on the oil separator box. Even when mine was blocked up with oil residue (after not even looking at it for 12 years) it never required "jamming" something through it. My first attempt was with a thin piece of wire. It slid right in. A pipe cleaner was too thick, but my thinnest drill bit was just the right diameter and length to fit. It never took any pressure, and didn't widen the hole, it just was the right diameter.
I would try the same with your new part -- gently slide a piece of wire into the orifice. You may find that indeed the opening is clear, it's just to small to use your mouth to test effectively, or even be able to see through clearly. I wouldn't think they would ship it from the manufacturer plugged unless some applications require that and others require it to be opened. You may want to contact a dealer or service center to see if there are any product notes or guidance available if it is indeed plugged.
Good luck -
