You should be able to see a hose from the throttle body to the rocker cover. The hose may be big enough to completely cover the PCV valve so you might not be able to see it. Pull the hose out of the rubber grommet in the rocker cover. You should be able to see the PCV valve once you pull it from the rocker cover.
