It's not a vent, it's a oil drain from the valve cover, have a good catch can setup and you'll be golden.

Oh so it really just a oil drain? It's not keeping the case under vac at all?

So just the front of the "T"is all you really need?

So should I just cap the back end of the valve cover T?

The blow-by oil gets sucked from it to the valve cover.

I would recommend removing the plug and putting an NPT or AN fitting there.
