Default Catch Can Gurus Help!

I seem especially dense today and am having a hard time figuring out how I should configure my catch can with only one nipple on the turbo inlet. I'm sure I'm over looking something, help me find it!

Yellow are T's

Currently (which I think is wrong...):


What I want to do, but feels wrong:


Feels better, but oil mist all in my bay?

Yeah... It doesn't. I don't have enough inlet nipples. If I don't vent one to atmo I wind up sucking straight into my inlet. Of course this is no better then what I have currently...

I need sleep.

What turbo inlet do you have? on the stock inlet there's a nipple for the pcv. That's where your lost. I think.... i know perrins v1 inlet doesnt have a nipple for the pcv and you have to T it into your head breathers. picture number three would be the way you would do it. That's what I would imagine atleast

The link above doesn't really help. It leaves me with a vent to atmo crank case.

Bump, I actually have time to do this now.

Make a new hole in your inlet and run two cans is the best way to do it. One can for PCV and one for breathers. Connecting the two systems is not correct. It'll be better to run only one system to the can and leave the other alone if two cans isn't an option.

The issue I had trouble understanding was why connecting the systems is bad. Excessive blow by in the crankcase can potentially cause air to be forced back into the breather vents- which should be under vaccum. Not only that but you are lowering the vaccum on each system if you t into the line because they both go into one nipple on the inlet which is creating the vaccum.
