This is what I am going to try for connecting the low pressure side to the Intake.

I have previously tapped the intake cover for 1/4" fitting to use as a dedicated vacuum source for the BOV. The point of course was a dedicated fitting...

But I am going to use that also for the PCV return to the Intake. Potential problems with this is I am taking the PCV line and reducing it from 3/8" to 1/4" at the intake AND I no longer have a dedicated line for the BOV.

If this turns out not to be ideal, the plan is to tap a new 3/8" fitting when I have it all removed for intake valve walnut shell blasting another time.
