*That was educational and interesting.*

*We had a tech in our dealership that developed a technique for welding the
horizontal freeze crack which often happened to the left side of the Ford
2N, 8N & 9N Ford tractor block. Ordinary nickle rod applied to a veed out
crack NEVER worked for all the illustrated reasons . . However, my tech
experimented with making a vertical cross bead about every 1 1/2" across
the crack. We think the cross bead stabilized the thin cast iron
and contracted to form a compression of the material to effect a good seal
action. After it cooled overnight, he would add a good leak sealer like
"Alumniseal" to the coolant and run the engine to operating temp. We did
dozens of them and never had a comeback. *
