OK, I just went to change the oil on my newly acquired W124 300D and found that the sump pan drain plug was in REAL REAL tight and seemed to have the consistency of butter, ie after a little pressure the bolt just rounded off.

So what next.....I don't really want to resort to taking it into a shop and getting a mechanic to drill it out.

Somebody has recommended Mole Grips (are they called this is the States?)...basically a wrench with a nice set of grips that you can lock into place. Once locked, giving it all the muscle you can to shift it!!!

Is this the best idea, or can somebody recommend another way to get this shifted.

Cheers
