Not Ducati but an engineering problem on my Fiat engine ,, replacing EGR its a well known issue that the 8mm bolts rust in place ,, 2 came out after lots of heat and pentrating oil and torgue hammer but 2 sheared with about 8mm clear ,, so More heat , more penetrating oils 3 days now ,, then Snapon gripping Stud extractor but still not budging they are totally rusted in over 200fy lb of torque used !!!!!

cant use 2 nut trick not enough thread above engine block and I cant weld to save my life ,, even if I had a welder.

its clear to me that the penetrating oil is not penetrating at all any ideas guys

drilling them out might be next option ????????? if I can get a drill in the space ???
