I'm debating on ordering the rr oil/air separator but can't understand how they have it configured. I'm guessing just by looking at it that the 2 lines coming off of the 2 crank cases are connected to the oil catch can? What stumps me is in the picture it only shows 1 blue line.. Has anyone installed one of these yet? pics?

 

If you look carefully at the picture you will see the lower line coming out of the PCV - see diagram

 

I thought there were 2 lines coming from each valve cover going to the intake elbow. All I see is 1 line going into the catch can..

 

Those are the valve cover vents. With the RR Racing intake they are changed to an atmospheric vent plumbed to the rear of the intake manifold.
