Ls2 pcv?
New to the LS2 and I have a few questions on the pcv system. After reading the shop manual on the 05, I cannot find reference to a conventional pcv valve, only a vague reference to a hole in the intake plenum.
The reason I ask, is that I am getting water droplets inside the oil fill cap. This car has sat for a long time with little or no road driving.
With the pcv lines drawing fresh air from the intake track, I was hoping this is only condensation.
Also, oil in pan is clear, showing no signs of milky contamination.
Thoughts?

Normal condisation in the oil. It will burn off when you get the car up to temp and drive it.
As for the PVC line on your 2005 vet LS-S motor, you have two lines (no PVC valves through, just straight through designs).
The first line is the one on the air filter system that goes back to the passenger side valve cover, and the second one is the hose that goes from the block to the intake after the TB.
So, the first hose is the snap on plastic 90* fitting into the accordion hose part of the intake line just in front of the Silver TB, and it leads back under the passenger side fuel rail cover back to connect to the valve cover.
To see the second hose from the block to the intake manifold, look at yellow on the hose in the below photo, follow that hose half way back towards the blue oil filler cap, then look straight under the top hose to see the lower PVC type U hose that routes the block gases into the intake manifold.
