David (MightyMouse) is a wealth of knowledge on this. I spoke with him at length before setting up my car.
Have his PCV can on mine with:
-10 from behind air filter to DS valve cover (clean air)
-12 from passenger cover to catch can (dirty air to catch can)
-6 from can to intake through a PCV (clean air return)
Very happy with the look and so far so good for the performance of it.
You can see the -10 on the far side in front of the brake reservoirs, and the -12/can/etc on the passenger side firewall.
