LS1 PCV system to a LS3/7 style....how to route it?????
Ideally it should be air thats been "metered" by the MAF, since that same volume of air ends up in the intake manifold once it has swooped thru the valve covers and valley.

what about PCV valve? and I like that setup, nice and clean/simple, is that valley cover pictured a LS2 on a LS1?

Just about all the engines made after about 2002 do not have an external PCV valve like the LS1 had.
LS2/LS3/LS6/LS7 all have a baffle arrangement under the valley cover and use that instead of an external valve.
