Re: (Praise Audi gods, pox on Bosch) HELP!!! somthing very bad happened to a spark plug

Well it all turned out not to be a non disaster.  Put some penetrating oil on for the afternoon and used a screw extractor.  It came right out.  Dont think I even need the oil.  On closer examination both plugs were corroded 3/4 of the way around.  No matter how they were unscrewed they would have parted.  Question is, how can this be.  Anyone else had this happen to a plug?

Now tomarrow I'll do the O2s and see what kind of other adventures I might wander into.

Cheers all,
