Can this be repaired?

I have a convector radiator in a one pipe system that has been leaking. I have since lowered the pressure of the boiler to .5, with 1 as the differential. The radiator gets hot all the way through, but it is leaking from what I guess is the air chamber (I can be completely wrong). Is there a way to repair it?

    You can choose to do what you want, but you cannot choose the consequences.

    Sorry. I have pictures, though I have cleaned the radiator since.

    Can you point to where the leak is exactly? If it's on a threaded connection, it may be repearable. On a solid piece of casting or the tube part, 2part epoxy or surgery with a screw, 2part epoxy and self sealing tape over it may repair it, but won't be a permanent fix. It all really depends...

    As @MilanD said, there are ways to repair the leak if it is in a casting or fabricated tube part (from the picture, I'm guessing fabricated tube -- could be wrong). The key to any repair of this sort, though, is that the surface on which you are applying the epoxy -- JB Weld -- must be bare metal clean. No trace of rust or oxidation. It doesn't have to be shiny -- but it has to be perfectly clean. You will want to wire brush it and maybe sand it, and wipe it with acetone of somesuch to get rid of any oils (but let that evaporate!) and then get the epoxy on there before it has a chance to rust again. You have about half an hour...

    Judging from the general condition of that convector and the rust through I see along the bottom edge on one of your pictures, which probably indicates a leak elsewhere in that convector, I'd consider a replacement, when the weather breaks.

    I can't make out where the leak is coming from. I just see that it runs down, and drips. I can also hear air escaping from the same area, but I don't know how to find it.

    Would you have any suggestions where I can find a replacement for it? I'm uncertain of the specific type. I know it's a
    semi-recessed fin tube convector radiator for a 1-pipe system, but I have yet to run across it's match through a Google search ..

    Some of the guys on this sight should be able to give you a couple sources.

    Check out Modine and Governdale as two brands that may have an acceptable replacement convector.
