if it's

the "V" series casting issue, I have had little to no luck with sealer, and I have tried.  The cast flexes just enough to open and weep again. If this was a pin hole or something else, I have never had Sid's Perma-Weld fail me, but that horizontal hairline crack that you are talking about is a no win situation. Have you looked into warranty?

I wouldn't

I had a bad leak in my 1945 5-section Smith boiler that developed in January of last year and I faced a similar problem. I considered putting some type of sealer in it, but decided it could get too much gunk in my pipes that could come back to haunt me once it was replaced with a stainless mod-con (where everyone seems to worry about passage size).



Instead I drained enough water so that the water wasn't forcing its way out, used grinding wheels to rough up the 12" crack, and used quickset JB Weld epoxy. I didn't want to wait for the slower set type. Believe it or not it worked, and got me through the winter (I had to repeat once when the first patch eventually gave out as the crack moved further). I was lucky the crack was accessible and not between sections.

same here

My father in law used epoxy to fix his V-75. Lasted at least 3 years. Finally went with the warranty replacement and that's been going for at least 10 years now.
