Steve, I would not consider myself an authority on this repair, but I repaired mine with no more tools than the average antique tractor owner would have in his tool box. A deck level crack, as Grandad said, will probably live with a new head gasket and not leak. My WF was cracked in 2 of the three lower web locations, between the sleeves @ the o ring area. I drilled the crack, dead center, to about one quarter inch of going through, then tapped it 1/4-20 (bottoming tap). I then cleaned the hole with brake cleaner & compressed air, next, fill hole with non hardening #2 Permatex or rtv silicone, then screw in a 3/4 or 1 in. long set screw to bottom out. This will cause a hydraulic effect, and pushes the sealer throughout the crack. Then I added a coat of JB Weld to the area of the crack that is exposed to the coolant chamber. If you dry fit the set screw, use a length that will leave about a quarter inch out, so it can hold the JB Weld, and the JB Weld will hold the screw. I made this repair last year and so far no coolant in the oil pan. Feel free to ask, if you need . CP
