PCV system 5.3 with ls1 intake (with pictures)
I have a 2001 5.3 with an LS1 intake. I am trying to determine the best PCV routing, I have attached a picture of my currently cobbled together PCV system which I don't believe is working correctly. I would like some guidance as to what route to take from here, maybe some clear photos of how to route. I will even consider running a catch can at this point but I am also very unsure of the routing of that.
Here is my Drivers side, it goes from a PCV valve in the valve cover that I bought to the intake on the drivers side.
Here is the passengers side, it goes from the port right up front on the passenger valve cover to the throttle body like it did on the 5.3 setup.

How do you plan on leaving the PCV valve in the valve cover?

Well the stock system also uses the rear passenger side valve cover port too. I planned to keep the PCV valve pushed into the valve cover, run the line from that to the catch can and then to the intake port. Rather than using a fitting in the valve cover and putting the pcv inline close to the catch can if that makes sense.
