Where is the PCV valve on a 1996 Ford Thunderbird 4.6?

The PCV Valve itself is on the right bank valve cover (passenger side), directly underneath the air intake plenum. The plenum will need to be removed for access.

The plenum looks like what? Any description or diagram would be helpful. It is a black rubber air pipe approx. 3-1/2 diameter. It runs from the air filter box to the throttle body. It is secured by simple hose clamps and can be removed easily with a flat head screw driver.
