Pic 1. yes should be to PCV, however if the other port is going to the PCV thats fine (it should not T/or branch anywhere. Just straight to the PVC.
Pic 2. No not good for cooling, they make a special 90 formed hose, find it
Pic 3.On my truck, the larger hose, goes to my brake booster.
Then one feeds the vacuum block mounted high on the passenger side of the fire wall (almost the top) it has 2 ports of it, that vacuum block then goes to the round vac reservoir on the fender, and the other one goes to the metal tube behind the engine that is hooked to the transmission vacuum modulator.
The third one is capped.
So it looks as if you have the same, except your transmission vacuum modulator is fed directly from this port, I hope the extra vac ports on the vacuum block on the firewall are capped or run to something, otherwise you have another vacuum leak.

Me??? Have a vacuum leak??? Nope, not possible.
I think I will move the PCV back to the center of the carb for cleanliness sake. Plus the line has a mix of rubber hoses and metal tubing. I want to clean it up.
As far as the other goes, it does appear everything else has a destination or is capped. I "think" I have fixed all the leaks for now.
I will keep you guys updated. Thank you so much for all the help.
Is there a good resource for me to learn more about the electrical and vacuum system. Honestly, I want to simply understand what creates vacuum and which devices need vacuum to operate correctly so I can configure everything correctly.
Thanks yall

I'm sure EGR valves can fail in a lot of ways. But I can think of three that cause problems. First, the diapragm can blow and you have a vacuum leak. Second, the valve can stick open and you have exhaust gas in the intake at all times and the engine runs poorly - especially at low speeds. Third, it can stick closed and you have no exhaust gas when you are supposed to have some. That means the engine runs rich and the economy suffers.
