If that circulator has not used up all of its nine lives yet? Turn it on its side so the motor is horizontal with the wiring box up and not in the vertical position it's in now.
( I'm not positive but I believe that the Taco company recommends a horizontal installation.}

Another thing you can do is install two of this type of Spirovent air separators (VDR-M series, See picture) on each of the two pictured copper lines. This Spirovent will eliminate all the air from your system as well as help remove any ferrous type material that may be circulating in the system.
Do that and then plug or cap the ports on the top of the green air scoop. Run a line from the bottom of the air scoop to a properly sized expansion tank.



If the circulator is truly dead then repair or replace it and install it horizontally with the wiring box in the up position.


Doing this should help to optimize this system quite nicely.

I wanted to install Spirovents but figured that the purpose would be defeated putting these AFTER the pump.

I also wanted to do away with the air scoop but with that humungous 3 inch pipe, my air elimination options are limited being that I'd be WAY over budget with a 3 inch spirovent Sr.

I wish that pipe was two inches but I like to dream haha

No, No.

I'm suggesting that you leave the air scoop and cut in this type of Spirovent on each of the two smaller-diameter copper lines.
The budget shouldn't be broken and would probably pay for itself over a relatively short time.
