Now if it was an intake coolant leak, you might get away with JB Welding it, but exhaust heat will eat up the JB weld in a couple of weeks, perhaps sooner. However, there are high temperature putties that would hold up to the heat, but I don't fancy their chances of holding the coolant pressure. If it's accessible through the port without removing the head, I'd be inclined to shove JB Weld down inside it, then cover over the top with the high temp putty...

I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
