exhaust stud snapped, then snapped again

This is on a 96 750 Nighthawk.

Needed to remove exhaust and the one cap came off with a piece of the stud inside. So I got a 7mm extractor socket and snapped it of even lower (no not intentionally). Now only about 3/8 of an in is extended. So I drilled out and am using an internal extractor now. Yes, I've been soaking it all along with pb blaster.

So to the question...Is it OK to hit the cylinder head with a propane torch to try and loosen old rust or whatever and expand around the stud a bit? I mean I know big explosions happen in there but this would not be so evenly distributed as it would be centering on an area. My guess is no problem I'm just over thinking it like I do everything but figured I'd ask.

My first thought when that happens is "Crap".
I would let it soak overnight and try again. PB Blaster may work. I have had much better luck with Kroil. Not available in stores and I am sure you don't want to wait for delivery. I don't think heat will do any damage, but I don't think it will help. When you get the stud out, clean the threads with a thread cleaner, not a tap. A tap will remove too much metal and the new stud could be loose. Good luck. Craftsman 48 pc. SAE & Metric Thread Restorer Kit

Penetrating-Lubricating Oils is where you get the oil. They offer buy one get one so it is a great deal. Even if you don't need it for this, it is great to have around.

Propane heat won't hurt anything. Remove the extractor, Heat it up, them soak it down with PB Blaster. As it cools, capillary action will draw the penetrant into the threads. I'd hit it a few times with the heat and the juice, letting it cool down in between.

Now I've always had a MIG, so my first reaction is always to grab it and weld on a stud..

Propane you'll be fine, there's enough heat to do the job but it takes a while to build so you'll have time, oxygen/acetylene is another story but it's do able ( done it) if you know what your doing. My experience with extractors has never been good.. I keep buying them though.. Maybe I hope they will work.

I snapped a stud on my 82 750 nighthawk, it's still snapped ran like that for years.

Good luck

used to work in a machine shop, customers would bring parts in with the studs broke off, drilled of center, broken ezeout in broken stud, we would use the mig to weld onto the stud and build it up so could weld a washer onto stud, then nut onto washer and stud, the heat from welding would usually help free it, the the nut gave leverage to move it back and forth some to free it up rest of way, but if this failed it was bad news, then parts had to be put in mill, and bored out.

If you can find these square type extractors the are strong and grip very well. The spiral type can wedge the stud outward.

If you use a bottom tap all will be good but using a thread restorer in aged cast aluminium may give adverse results also if there will be any threads left at all. This may end up being your repair option. https://www.belmetric.com/index.php?...FQaPaQodTA0C1w

The heat will not hurt it. The trick when heating parts to get them apart is to heat it fast, before the heat can transfer to the stud. If you can get a helper to keep pressure on the stud while you heat it, that would help. Welding on parts works well because the welding draws the parts. We do this at work to remove bearing races, we run a bead of weld all the way around the race, turn the housing upside down and as it cools the race falls out.

You can also heat it up and touch paraffin wax to the threads, when it cools the wax will be drawn up into the threads.

Good luck and be careful.

Thanks everyone for the great advice, I don't know how to weld, wish I did. Will be hard to heat it fast with a propane torch but I will give it may best shot and feed it pb blaster.
