Re: Alfa 156 JTS Oil and Sump Problem
If the hex is completely rounded they will need to slot the bolt with a fine disc cutter, and a very large header blade and need to turn until it snaps or sheers or releases, smacking the hell out of it with a dot punch and a hummer is really going to balls things up.
Once the little buggered sherred, they should be able to either reverse drill and reverse tap, into the old thread, put a new bolt in and unbolt it, failsing that, drill it right out, and clear up the thread.
They should only replace the sump if they have chewed up the alloy arround the plug, or if a after all that a new plug doesn't seal.
Can't suck out the oil.. you kidding, a silicon tube down the dipstick and a vacuum oil sucker device thingy, like Mercedes use.
Sound like a back street garage to me, get it to someone who has some mechanical knowlege, not just Haynes 101.
