What is the big hole at the rear of the 5.3 drivers side stock valve cover for?

It has a rubber grommet in it and looks like the grommet for a PCV fitting.

I have the LS6 Valley Cover and a line on the front of the Passenger side valve cover. Do I really need a PCV in addition to that? This is a 2001 motor.

Got it! I also have an LS6 intake that has the port for the hose from the valley cover and a truck throttle body that has the fresh air port going to the passenger valve cover.

I already have the rear steam lines plugged and also have the front crossover steam line.
