I managed an apartment that had radiators and used steam for heat...

They had relief valves on one end and seemed a little messy, the system

Would cool down and water would return to the boiler... The heat would

Come on in the morning and the relief valves would spit and sputter

Til the system was hot, had many compliments on how good heat was...

Had to fix relief valves in many apartments to get the heat...

Maybe there is a way to catch leak, and not interfere with operation

There are craft thingies on the internet, maybe they have ideas...

I am bleeding today too. One of my bleeders is that type and you have to leave the slightly loose.
