Well done Mart. Your hands-on problem solving skills are exceptional. Thanks for posting such a complete and detailed video. There is no doubt that drilling the 1/4 in. hole in the stud allowed the arc welding to work.

I would think it takes some skill to make sure the arc welding rod remains inside the 1/4 in. drilled recess and does not come in contact with the threads in the block that are above the broken off stud. Otherwise the broken stud could not be backed out if the threads above it were "buggered" up.

Would it be possible to drill and tap the stud with a 1/4-28 LH thread and then back the broken stud out using a 1/4 -28 LH bolt?

Does the welding heat the block enough to distort the deck surface
or effect the hardness of the valve seats and surrounding cast iron block area?
