This is my oil fill cap. I’m not sure that I see a valve or is it the entire elbow?
Valve cover on the other side (passenger or left side) will be toward the back of the engine.
Yeah, this is where your PCV should be, in the cap. I can see from your picture that the rubber hose from your fill cap connects to a steel line that I assume goes to the back of your carb, with another short section of hose. That's the pcv line. I can't tell in your picture if your elbow in your oil fill cap has a valve in it or not, kinda looks like it's just an elbow without a valve. But this is where one would go, at least on my 73 Q-code. Here's pictures of mine.
