hey, what ended up working for me actually was grabbing one of those carbide drill burrs from home depot, and kinda carving it out with a dremel. This thing threw small chips of it right out, my idea was that i got the first 'hardened' layer off, and try it again with the carbide drill bit...

So I'm trying the alum trick, and I don't see jack. No bubbles, no black thingies, nothing. It's a very saturated solution of water and alum. I'm keeping an eye on it, and alum accumulates to the surface of the bolt and I just knock it off. What's going on? Is my mixture not pure enough? Maybe...

yeah, i have a feeling that metal amalgamation in there is all hardened up now, so no matter what bit i use it's just not drilling. i ordered some solid carbide bits, apparently i can't use that with a hand drill... i also hear a carbide burr could skim that top hardened layer off and i can keep...

I was worried about heating the stud too much to bubble the alu, but I only have a mapp gas torch. Also my welds just doink right off after the slightest amount of force with a breaker bar, so maybe this would help penetrate it more?

Just passed the 4 day mark for me....

Yeah, now I know. If it broke off a head, then ain't no way an extractor would even touch that stud.

Rare yes, valuable absolutely not. People tend to junk these engines because parts are so hard to find and they hardly make any power. Sound really cool, though.

Did some reading, I could cut an aluminum cup in half and have it held up onto the bolt, while heating it up pretty good with a lamp or something

This sounds interesting, so the idea is to use a cup, to keep the liquid on it, and heat it with a lamp?

I think extraction is out of the question since it broke an extractor trying to get it out. I just want to drill and helicoil. Or dissolve or whatever

What if I made a jig or something? Either 3d printed or made one out of wood? Something to just keep it straight on

It's off a Toyota 1g-gte. Very obscure and old engine. I don't know. I made a mistake, and now I'm more than suffering the consequences.

How much does that cost? Yeah, I mean I could probably keep trying but I feel like that bolt is jammed so well in there that even if I got a perfect weld in, it would just break the nut again.

Stacked up some weld on it, ground it flat, then I punched a center on it and I started drilling... Got through what I felt like was the new weld, and all my new drill bits just stop DEAD right at the stud. Am I doing something wrong here? I'm using oil, low pressure, high pressure, I'm straight...

Yeah, listing says it's M2 HSS, which is probably why it broke so fast. I thought cobalt would chew through it too but it's not even making a dent.
