Default Rerouting the crankcase/valve cover venting system, need help

6. The OEM PCV and crankcase venting system seems way over complicated. Why do they put 2 vent ports on each valve cover and right next to each other? I see the crankcase vent and it then goes UP and over and then back down to the valve cover vents. Why? Why not just run straight lines to the valve covers? Again seems overly complicated to me and make it more complicated than it needs to be, unless there is some technical reason they do that. I will be installing my own AOS and just want to run the rear vents on each valve cover and the crankcase vent to the input of the AOS and cap off those other vents in the valve covers. Can I do that? And what about the PCV valve? Where/why is that there? How is where it's drawing from different from that large crankcase vent? I must be missing something here.
