Manifold Hose Nipple removal

[SuperNovaSS]

The heat should. In fact, it should be easier to remove as the compound most likely slowed the corrosion between the dissimilar metals. Eric, the wax trick sounds good. I've never used that trick but will now.

If you have a box of Crayons in your home and If you have Kid(s) give it a few days and you will have twice as many crayons.
Great tip.

KROIL, found at most auto parts stores. Works on rusty submarines good enough for a Rust Chevy.....

None of the above has worked for me.What happens if there is corrosion is the aluminum transfers to the steel and when you unscrew the fitting it tears out the threads.The only thing that works is to drill a hole if its a plug.Then take a jigsaw and slowly and carefully cut from the drilled hole towards the thread stopping short of the alum.Then with a Vice Grip collapse the plug or fitting then unscrew.

Same for mine I sent the manifold to Jerry McNish after I ended up cracking it along with the threads stripping out he did a great job fixing it
Can't even tell now
