Oil catch can/s

I've started working on the Sy again & I'm trying to decide what to do about breathers for the aluminum valve covers I have.
I don't want any oil in the intake tract, but I'm not sure how to plumb it to get the best results.
Open breathers are out 'cause they are to messy.

What I'm thinking of is 2 of these, 1 for each valve cover, with the other connection for each being pre-turbo, somewhere in the elbow or in the end of the air filter. That way I should have plenty of vacuum to draw blow-by from the crankcase when the motor is at speed (my theory).
This setup won't allow any fresh air into the crankcase.
Do I need fresh air into the crankcase?
Disclaimer: This will be a track only setup. ;)

I did something similar. I have 2 of these from jegs $80 each.

I then have a -10 line from each valve cover to the breathers which are mounted near the headlights. I didn't want any dirty air back in the intake tract as you said. They do have breathers on top, but I have yet to see any oil or even film coming out. I did open the drain the other day and no oil either, very small bit of condensation but was maybe a spool full.

I suspect the 3' of line from valve cover to breather is helping keep the oil away, yet let the crankcase bleed off the extra pressure.

My can is clear and has the filter inside--just installed it the other day--breathers on each valve cover(screw in style)--plummed over to the can. I'll post my results.

Do you get the smell of gas/oil in the cab with those breathers?
