You might need a new jug depending on where the leak starts at. If it's up on top and is leaking around the head stud, grooves could be etched by hot gasses and sealing the outside would do no good. It will just blow off.

What I don't understand, is the hole in the part where the stud goes through or is it near the intake port? If it is coming out the stud then a new jug, piston and rings will be needed. There are more problems than JB Weld can fix :p

it will work though, i have used jb weld for many many things. i have used jb weld on my old cars exhaust system and manifold. it held, im more than willing to bet it would fix this too, just use alot of it and make sure you mix it very very thoroughly.

There are better versions of JB that are stronger and more resistant to heat... JB is kinda like the cheap version....although it does work wonders. :D
