PCV Valve Help

I've been getting oil up in my air intake, so the first thing i thought to check was the PCV valve. I bought a new one, and went to put it in, but I can't find the damn thing. I'm starting to even wonder if the car has one in it. It's a base model 91' Cavalier, with a 2.0L 4-Cylinder. If anyone can help me, I'd appreciate it. I'm going insane trying to find some info on this.

It's in the left side of the valve cover held in by a big black plastic nut. When you remove it make sure the O'rings are still there, I believe there are 2 of them.

Thanks for your help. I appreciate it!
