G'day Cedric About the only thing I could suggest, if you haven't tried it already, is applying a little localised heat, possibly from an oxy-acetylene rig on a lowish heat. In theory this will expand the case around the stud or a stuck bolt, and allow it to turn.
I have been told you should never remove a spark plug from a cold engine for this reason. Cheers, Rob. Robin Wills Second Person, Pacific National KR-2 19-4594, Ser# N111 krvia...@bigpond.com
