hey, i dont think Jbweld will melt away, but given the right surface, it will peal away. which makes me think that JBweld would or could be prone to leak after part of it after many heatcycles loses contact with the surface. probalby could leak like two pieces of metal without a gasket. again, a guess on my part.
What I do KNOW, is JBweld saved my race weekend and has fixed a huge leak in my radiator by stuffing a bunch of it around the hole. 7 years later, its still holding!
(but it also was a paper mache mix of JBweld and toilet paper stuff into the area of the leak and the cross tube was pinched togther to reduce the hole size)

....a short story about an experience I had with JB Weld a couple seasons ago.
after the 3rd race on a new motor, I sprung an oil leak where the lower engine case mates to the engine block. This where the Loctite 574 is applied, and as you know, contains pressurized oil galleys.
either we did not apply the 574 correctly (which I doubt) , or someone got their fingers into it and wiped some of it off before we mated the pieces together (thats my guess).
whatever the cause, the hot motor oil was squirting out under pressure.
the correct repair of course was to pull the engine out, split the engine, re-seal it and re-install. NOT something I wanted to do mid-season.
I washed the crack with brake cleaner, dried it out with a air hose, and trowled on a smear of JB weld over about 6" of the joint. I used a toothpick to push it in where I could.
I know, I know, a hayseed repair, but I had nothing to loose. The engine had to come out anyway.
That repair held agaist 90 psi of hot oil for the entire rest of that season... and the next season too.
When I did finally pull the engine and take it apart, we had to whack that JBWeld with a cold chisel to crack it and make it let go.
When prepared correctly, and applied to clean (oil free) surfaces, we have been very impressed with it.
