PCV valve location
All -
I apologize in advance for my limited knowledge. My '74 F100 has a 360 with a 2bbl Ford carb. If I'm correct about this point, the crankcase breather filter in the round breather on top of the intake manifold was connected to the cap on top of the valve cover by a small hose, possibly with an elbow or two to make everything line up more easily than it otherwise would have. I always thought there would be a PCV valve right on top of the cap on the valve cover. Am I correct about that? My engine, which wasn't well cared for under previous ownership, has no such valve, and I've read a couple of threads that refer to the valve being connected directly to the carb somehow.
Any help clearing this up would be greatly appreciated.

Usually it's in a grommet on the RH valve cover on an FE and connected to manifold vacuum, and the breather is on the left and connected to the air filter housing. . but it doesn't matter as long as it's above a baffle so it doesn't pull oil.

It's anything except for the small inlet on your carburetor for the vacuum advance with ported vacuum. typically your PCV will be hooked to the rear of the carb or the spacer just under it. but it doesn't have to be.
It's not ignorance it's inexperience. you're learning and that's good.

Amen. Gotta learn somehow. This is a good place to do it.
440 is correct as usual. Valve is on the right (passenger’s side) valve cover and the rubber line (typically a 3/8” vacuum hose) connects said valve to a port at the rear of the carb. The original setup on our 73 had a hardline spliced between the two rubber soft lines. Probably not necesssary.

Showing some ignorance would be NOT coming here and asking questions.

Your patience with and kindness to me in my many inquiries is greatly appreciated. I hope to be able to provide the same service to others as I gain experience in my journey restoring my old truck.
Godspeed to you, sir, in all your endeavors.

Thank you for your encouragement and your detailed description of where it is located and how it is connected.

That said, probably everyone on this site would like to hear the story behind your avatar picture; I'd wager that's a whale of a tale.

Back in 1975 I lived in Torrance, CA and was 20 years old.
I altered my temporary paper driver's license so I would be 21 years old and joined the Los Angele Playboy Club and kind of became a regular.
It was a "high class private club" and I was the youngest one there. Most of the people there were 40+ years old.
There was no nudity. These Bunnies were cocktail waitresses and you could have a photo taken with one of them, a Polaroid for $5.
It was a great place to take my friends from back home when they came to visit for a nice dinner, drinks and entertainment.

I was living with my oldest sister at the time and working in a body shop.
Those were good times for me.
