The only change I can see is I'm feeding the filtered air directly into the throttle body instead of the turbo. The oil is still going to have to drain to the crankcase regardless of how you route the rest of the system. Please do enlighten me though. If I'm going to cause problems for my oiling system I'd like to fix it.

You'll want to install a check-valve between the manifold and AOS for two reasons:
- the stock pcv valve leaks
- not having one means that every connection between the manifold and the stock pcv (the can itself) is a potential boost leak
