Check Valve needed? Valley to blower??

Redoing some stuff on my crankcase evac and I need to know the answer to this question.

If I run a line from the intake valley to the suckside of the blower do I need a checkvalve installed?
In my thinking I don't since I don't see how the blower could feed flow into the intake valley since the blower is sucking instead of blowing, lol??

Or is my thinking all wrong, please explain.

Ok thats what I thought. I am actually an LTx guy, but the same concept.

Let me ask you this, what is the difference between the LS6 Valley and the LS1?? I am guessing the LS6 vents better. Wouldn't mind seeing some pics between the two.

ls6 valley has a pcv system built into it. the ls1 is just a cover...the pcv is pulled from the valve covers instead

Any pics of that baffle? I am in the process of doing a sheetmetal LTx intake and I am going to have a -10 on the valley and I need to figure out a baffle setup.
