Maintenance Problem

I went looking for the PCV valve on my '02 ETC today without success.  I remioved the plenum cover and found what I thought was the PCV valve on the rear valve cover on the right side of the engine.  It had a plastic hose with a rubber connection that went to something that resembled a PCV valve, however, this PCV looking thing connected to the valve cover did not want to be removed.  It was all I could do to twist it with a pair of channel lock pliers.  The front valve cover also has a plastic tub running to it with a rubber connection to the same port looking thing that is on the rear valve cover on the left side of the engine.

My question is "where is the PCV?"  If this thing on the rear valve cover is it, how do I remove it?

Thanks.

Slowroll, do you have any suggestions?  Thanks.

PCV valve is a fixed orfice design, it doesnt rattle. Located in rear valve cover on passenger side. It's not normally serviced, "dirty air" tube going to it is designed to be cleaned or replaced.

Thanks, I knew you would have the answer.
