We ran two treatments of Bars Stop Leak tablets through the system and could only slow the leak down. We re-pulled the engine and the freeze plug was OK, but we noticed a small dimple in the cast iron where a small bead of water dripping. I was able to take an awl and with a little pressure put the awl into the block - water jacket area. The hole is approximately 3/16" diameter.
Discussed this situation with a cast iron welder and he stated to risky to weld, it appears to be to weak of a spot. ANY IDEAS?
Could I set a screw in the hole and epoxy the screw to plug the hole? Would I need to tap the hole? Any suggestions or ideas are appreciated.
You put 2 cans of bars in a new engine. Whatever you end up doing to fix it make sure you flush all that crap out. It will ruin your radiator or heater core in no time at all.

If you can drill and tap the hole and put a plug in it with some sealer on it
