Model T Ford Forum: Classifieds: What flux?

I have a brazed repair in a water jacket that has a leak, otherwise everything is good, the babbit is excellent, and it's a '14 block so I want to use it, not replace it. I've seen the threads on soldering cracks and mention of Tintite flux to solder a cast iron block, but I don't know if that's OK with a brazed area. My thought is to use a cutter and remove the small areas that are leaking and solder them.

Any ideas on what I should use? I can take this to a local shop and have the brazing touched up if necessary.

I'd use Belzona Epoxy Repair on it Gary - pricey even for the small kit - 2 part epoxy but it's the best available. If you were a little closer, I'd have you throw the block in the car & head to Washington - I'd fix you right up !

as Steve stated ...there are several adhesive type materials that can effect a positive seal of non-structural cracks in motor blocks ...I have used super glue and also locktite porosity sealers while applying a vacuum to the block ...a good shop vac. can suck the sealer into the crack ...as with any repair , the preparation is important ...with sealers a good cleaning is critical ...hope this helps , and good luck on your project ...always an optimist...gene french
