I haven't actually run the car yet, o I can't vouch for the method but, I choose to completely remove the PCV valve from the equation. Plugged the hole in the intake manifold and everything. It was the simplest low maintenance method to still recirculate the majority of the air.
The method I used is to just completely remove the spider hose, T in the valve cover vents with the crank case vent, run that combo of lines into the catch can and then run a line out of the catch can into the Y pipe. Let the N75 VTA (yes it's technically an "unmetered air leak"), and don't have the PCV valve/manifold vacuum source at idle. The argument against removing the PCV valve and manifold vacuum is that there won't be any way to pull the gasses from the motor at idle, but many people do the F hose delete on early style spider hoses and have no problems. I think the more realistic problem has to do with a 15 year old pancake valve and PCV valve letting too much pressure or vacuum by and blowing out top end seals. There isn't a more "right" or "wrong" way to do a PCV system. They'll all have their ups and downs. I wouldn't recommend a vent to atmosphere system though. They get smelly and leave oil residue everywhere. Just personal experience with a 1.8T.
