PCV was designed to work on an intake that never sees boost. Without a check valve you will pressurize the crankcase and cause extra blow by. I originally forgot about this and blew out a valve cover gasket.
Just look at all the hoses and figure out a way to route them so they don't have see boost or add a check valve.

With the breather on that oil cap you can lose the small breather and just cap off that port on the valve cover. What you do with the driver side valve cover is much more important, it needs to either have that small breather coming from the pcv valve or a check valve inline between the pcv and the intake.
