I have the front of my T capped.
The rear of the T is run into my catch can AND is T'd into the drain fitting behind the turbo.
The PCV on the intake side is replaced with a hollowed fitting and also run to my catch can.
My catch can vents to atmosphere.
I have never, across either SR cars, had issues with filling up my catch can. Even now after 4 full track days, there's not more than a little film of oil in my can. Both were S13 SR's with stock VC's.
So no issues filling my can and no oil in my intake tract. Unless I'm going to blow something up I have no plans to change it.

It sounds like you are sending boost right into the atmosphere. If you have a "hollowed fitting" you mean empty, such that boost from the intake manifold can run right into your catch can?
The T should not be capped either. Not to be mean or rude, but you obviously have no idea what you are doing. This is the 14th page of this post, did you read through pages 1-13?
I just want to point you in the right direction. the idea is to pull a vacuum on the valvecover. I dont care if you use a vacuum pump or the engine as the pump or the exhaust as a scavenging utility, use all three if you can all at once. The better the vacuum you can pull on the crank case, the cleaner the oil will be, the better the ring seal will be, the more power you will make.
Consider this. A vacuum present at the valvecover will also be present in the oil pan. The head is connected to the block, and there are holes for the passage of oil from the head, to the oil pan. That said, you could technically fabricate a pcv system that pulls vacuum from the engine block instead of the valvecover, there is simply no good reason to however.
