This does not really explain how to remove this type of pcv valve. As I said, it looks as if it is pressed in. So do I just carefully pull it out with pliers or is there a better way? Thanks for the help.
It is part of the valve cover and the whole valve cover has to be replaced. If you squirt some carb cleaner in the hole and let it sit for a couple of minutes then reconnect and start the truck that will clean it out. You'll know your getting air flow through the PCV valve because when it sucks it out you'll get some smoke from the exhaust.
