Manifold Hose Nipple removal

[COPO 70 RS/Z28]

Ill Give it a try, It looks like who ever installed the Nipple (long long ago ) Many have used some form of brown colored compound.

Maybe form a gasket ???????????????

Ooooooo.....that's nasty stuff to work with if it's the one that sets up hard.

Good luck!

Do ya think the heat would break it down???????????

[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.

Crayola crayon also if you have kids

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.
