Removing cured epoxy

[Roseand]

I have an intake manifold with the crossover filled that I want to redo. Is there a solvent I can soak it in to soften it/Debond it? Heat?
It's an oem 760 manifold so if I have to grind it out I'll just pickup a new manifold. Just seeing if there's an easier solution. I believe it's either JB weld or devcon and seems to be bonded well.

Heat is your friend Bro, put it in the oven it should be good at 275- 350 check and keep checking. It will get real soft. Downside is it will piss off every one in the house and dont let it harden (cool) afterward until your done or basically you just heat cycled it.

I used a heat gun to soften the epoxy on my pump shoe.. 200 deg and It starts getting soft. Might try that if oven isn't an option

I put a heat gun on it for a few minutes, then the epoxy was soft enough for me to stab it with a screwdriver and it broke away with ease. Completely debonded from the aluminum so it is nice and clean!
Thanks for the advice. And yes, it definitely stinks!
