PCV & Oil Catch Can

[Jccck]

So i've been having some dilemmas with my Catch-Can setup on my Boosted F22A.

I started off with two Breather Hoses from the Valve Cover (one with a PCV ofcourse) going into the catch can.. And then venting to atmosphere.
Never had any issues, but i really need to legalise it.

So i ran another hose from the Catch Can into the Intake between the Air Box and Turbo.

From all the searching i've done.. It seems that this should work.
However it caused a bit of pressure buildup in the crank case and a small amount of blue smoke while idling aswell as driving.

When you would remove the Oil Cap and block the Breather Hoses from the Valve Cover quite a lot of gas is expelled out the hole (Not uncommon for a Honda, and my Cylinder Leakage Tests confirm there is no issue)
But when the Cap is replaced, and the Breather Hoses reconnected.. I instead remove the Catch Can Cap.
And the amount of gas being expelled from the Catch Can is easily half as forceful as to what was coming directly from the Valve Cover.. Does this indicate a restriction problem?
And another question.. With the setup described, does a PCV or Check Valve even need to be present? Surely because both hoses are now entering the Cold/Upressurised side of the Turbo i no longer need them.
(Infact i could probably get away with blocking the PCV port off entirely, and running one line.. But i think i'll need two to prevent further restriction)

I am now about to bore the holes in the Valve Cover large enough to fit a -10AN fitting.
Which have about twice the internal diameter of the stock holes in the Valve Cover/PCV.
And will run the same size hose (I think it's 5/8"?) as i was before.
I will NOT run a PCV Valve, and will upgrade all fittings in the Catch Can and Intake Pipe to -10AN also.

Can anyone see the new recircuated set up causing an issue?
Any better ideas?
From everything i can find on the Internet it 'SEEMS' that the -10AN fittings and hoses will be more than adequite but that makes me wonder why the stock lines are so tiny and there is no issues caused from them when your Motor is standard.
But, i just want to confirm it before i wreck a Valve Cover.

I have also read about a 'Bypass' system where the gasses are vented straight into the exhaust.
But i have no idea whether or not this is legal and can not find any information from the RTA.

Cheers!
