I have not, but I can report that leaning on it is a sure way to break it.
It's very fragile, breaking it may well be the only way to remove it. On
the last one I worked on, after breaking the bolt & removing the fitting, it
became apparent that the bolt protrudes into the water passage enough that
the end was caked with hard water deposits too thick to pass through the
hole. I wound up destroying the remainder of the bolt in place, trying to
save the threads in the manifold.
Something like "C-L-R" (US brand name product containing phosphoric acid,
designed to remove Calcium, Lime, Rust from ceramic, glass and porcelain)
might work to remove the deposits, but it's also going to attack the
aluminum. I don't know if it would clear the deposits before ruining the
manifold or not.
