PCV fitting on center bolt valve covers
That rear drivers side PCV system connector (rubber grommet) is smaller than on the old 98 covers. I just bought a PCV valve from Autozone, ground down the end of it, removed the spring and valve (guts) and used it to push into the rubber grommet on the LS6 cover. Like I said, you need to remove the guts of this PCV valve, because you already have a PCV valve halfway down that hose.
Ron,
