Default doing away with the pvc valve.

going to ask here first.

has any one, picked up a second passenger side valve cover.
done away with the pvc system, connected both sides with a T and run a catch can only before the tube connects to the throttle body???

how was your results on block pressure?
how often did the catch can fill up?

I think krambo did something similar but he also used the LS6 valley cover.

I still have my PCV but have considered doing away with it like krambo did. Before my 5.3 let go, I was getting a lot of blowby and just ran the pass side cover to a catch can and plugged the TB inlet. It helped quite a bit actually. The can caught quite a bit of oil and stopped blowing oil from my dip stick tube, so I'm taking that as case pressure went down.

Look up spoolin's old posts from late last year. I think he had some success.
