Default LS3 Top End PCV Routing

Hey guys, I just finished a 408 LQ4 with an LS3 top end. I have an LS3 drive by wire throttle body and I need help with my PCV routing. I will run the short crossover line from the LS6 Valley cover to the passenger side nipple on the manifold. I'm going to plug the Drivers side valve cover outlet, but where can I get fresh MAF'ed air from to the passenger side valve cover inlet?? Thanks

I would like to run just the MAF and Filter on the throttle body. Not a long air tube. But it looks like I might have to in order to drill/tap the tube for a place to get fresh air from......?

?? I can't find anything. Thats why I posted this thread. There is a lot of talk about PCV routing but everyone has dbc throttle bodies where you can find clean air. I can't find anyone who has a DBW throttle body.

I see. Just plumb the fresh air side in the intake somewhere after the filter but before the tb. Should work fine lots of cars come this way even the GTO iirc.

a lot of guys grab the fresh air right before the throttle body, just make sure you pull from a spot after the MAF. i've got a 90 bend right before my tb that i'm grabbing from, just had to add the nipple, but not something hard to do
