3B/AAN PCV with no turbo inlet pipe (on VEMS)

Those of you on VEMS with no turbo inlet pipe, where are you connecting your PCV to? I realized the other day I have to run without the factory inlet pipe or drop money on a 2.75" inlet hose from 2bennet or 034.
So I'll just run the diverter open to atmosphere and maybe grab a couple of cheap 90 degree couplers to put a filter where the stock airbox goes, may even leave the airbox. So I could weld a port onto whatever I rig up for that, but I know I've seen a lot of VEMS setups with a filter right on the turbo. What are you guys doing for your pcv setup?
Thanks

We're just venting to catch cans/atmosphere.

Something similar to this is what I'm doing... Front of valve cover to a Provent vented to atmosphere.
I thought about draining back to the oil pan, but figured I rather to keep that gunk out instead of bringing it back in the system.

So you're just keeping the crank case at atmospheric pressure? I was hoping to be able to keep it under vacuum, otherwise you're just venting pressure instead of actually evacuating vapors

When running higher than stock boost, I'm sure the vapors are being pushed out with ease. Especially on a loose motor where rings are worn. I've thought about plumbing in vacuum on mine but not sure it's detrimental to vent to atmosphere.

You'd pull a vacuum in an ideal situation, but it isn't hurting anything not to (as mentioned above). I wouldn't put much effort into it until you start making 600+ hp. Even then it's debatable. I don't think Gerner runs a vacuum pump...
