I've successfully broken a glow plug trying to remove it.  Luckily, it
seams, the nut-portion of the glow plug broke away from the rest of the
body.  It seems no damage was done to the glow plug/head interface.  The
seal of the cylinder isn't broken so to speak.

Anyhow,  I'm looking into how I'm going to get this out without removing the
head.  I see in the harbor freight catalog there's a diesel glow plug
removal tool.  Something tells me this is helpfull when the glow plug hasn't
already broken.

Does anyone know for sure?

Anyone have a solution?
