Re: Coolant drip
Sounds like they did ok, it all depends on the quality of the cast iron. Some you can weld, some you can’t.
I was a welder in another life, still am but just for myself and friends. I’ve welded up a couple dozen blocks with broken water jackets.
Rough procedure is to drill a stop hole, use a carbide cutter to cut a “v” in the crack, preheat, weld with nickel rod, post heat, stress relieve.
I had 2 that I could not weld up because of poor casting material. You know instantly because the block will “pop” and another crack will be right next to the weld. Usually the popping will happen in post heat or stress relieving.
If you don’t trust the weld have it dye penetrant tested.
