Well I took it to a welder and he told me it shouldn't be a problem as he was experienced in repairing cast. I believe he used a mig welder dedicated to flux core use. The Weld looked pretty good and he said he thought he had it. I paid him and took the car back to the shop and put the radiator on, was filling with anti freeze and it was leaking pretty bad. I drained it and took it back this morning. This time we plugged it and tried filling with water to only find it leaking again and again. His last try was with silver and a torch and it didn't work and actually caused a new crack to go laterally above the lower crack.
He did tig it also.
I'm not sure if he just didn't know what he was doing or just bad material to work with. My block may actually be ruined. I may try lock stitch or grind all the mess off and try JB Weld.
I really thought welding it was a safe way to go.
Can you use any screws or small bolts for lock stitching or is there something special about the lock stitch kits and bolts?
Any suggestions other than I told ya so's.
