The PCV valve is not in the cap that you unscrew, it should be in the valve cover under the cap; all you’ll see of it is the small end.
It usually takes a pair of pliers to pull the valve out of the cover. Once you have it out there should be an O-ring seal around the main body of the valve; this O-ring may get stuck in the valve cover; make sure you switch it over too the replacement valve. Some designs also had a second O-ring seal around the small end of the PCV it also needs to be installed on the new valve.
The valve almost has to be there, if it were missing there would be such a large vacuum leek that the car likely wouldn’t run worth crap at idle, may not even idle at all.
