Any water hammer noise? What size is the pipe to kitchen?
Is all the piping insulated?0 -
No noise.pipe is 1 inch I think,same as rest.no pipe insulation. Pipe leading to and half the radiator are very hot. I would think I would hear hissing with vent removed.Return line vent was completely clogged0

If you took the air vent off the radiator and all the other radiators are hot, your boiler might be under sized.
Have you checked the system size by measuring all the radiators?
How many radiators do you have?
Are the air vents adjustable?
If you can close 2 or 3 of your other radiator vents, you may be able to deliver the steam to that last radiator.0 -
Vent on radiator? Return line vent? What return line? I'm confused...Br. Jamie, osb

Insulating all the piping might get it there. Pipes were most likely insulated on original installation.
The basement piping has turned into radiators below your feet.
