The water jacket on my c engine is cracked
on the carb side water jacket. The crack is about
2.5 inches long, with another crack on the
other side of the drain hole. I feel that I have the skill to weld the block and retain
the strength needed, but am not sure that it
would be water proof. Can anyone recommend an epoxy or a sealer to be applied to the inside
of the block, after the weld.
thank you

If the area is clean, ground out clean, like a dentist cleaning out a cavity and you put JB weld in it will probably be fine. Make it clean and the grinding marks will allow the JB weld to adhere.

I work in a heavy truck shop for a utility. When small cracks appear in cast iron blocks, or thermo housings on our trucks or equipment, or whatever, we use a product called JB Weld. It's a two part epoxy that you mix together and apply to the crack. Cures in 24 hours and it works great! Seals that bad boy right up. You can even file of grind it afterwards. I get it at a local Napa store here in Jersey. This is a good question for the engine "guru" on this site Dick L. Hey Dick are ya out there?

You could try the "model T" method of sealing it - start at one end of the crack. Drill a hole and thread it. Insert a plug in the hole (one of those with the square indent made for a 3/8" socket drive extension to fit into or perhaps one with an allen wrench indent - important thing is that the plug doesn't have a head). Move over about 2/3 to 3/4 the width of the plug (away from the indent used by the tool to tighten the plug) and drill the next hole, drilling a portion of the existing plug out. Thread and insert another plug. Repeat until you've covered the entire crack with plugs.

Of course, your welding ability on cast may be such that you would weld instead of trying this. My cast welding ability would make me either try this or take it to my local machine shop ...!
