leaking steam

Check the PH of the system water, Shawn. You're rotting out the mains with excessive acidity in the water. I've seen this quite often. The system has most likely had poor or no maintenance over the years, and bad vents mean a lot of new water and oxygen in the system, which will always lead to corrosion of one sort or another.

insulation ?

Are the mains that are rotting not insulated and how is the near boiler piping.I,ve ran into the bottoms of main leaking from excessive condensate in the uninsulated mains it groves the pipe from the excessive condensate flow usually shows up near the threads .In most cases i,ve run into the basements or crawl spaces where un insulated and pretty much as cold as out side at times .The homes usually heated very uneven but with very large homes there are wings that don,t even see the light .Good luck and follow al,s post also and check your water ph and while your at it why not give the boiler a water side clean drain the mud legs and such i know not many do it but it should be done peace clammy

Another thing that can cause this

is improper air venting. Insuffucient vent capacity can cause the CO2 in the air to mix with the condensate, turning it into carbonic acid.

also on all the radiators the vents are in the middle should they be at the top of the radiator also the breaking pipes are all around not just near the boiler
