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.
