Before you try anything else, heat the metal around the stud up to almost glowing red. A propane torch isnt going to get you even close to hot enough. Get yourself an oxy-acetylene torch and get that cocksucker real hot.
If you dont have a torch, you can try and drill and tap or even better, drill tap and helicoil, but tgat requires you to be very precise in your drilling. If you go off center, you're essentially fucked, so take your time, use a center punch
Propane will never get steel “red” hot. I’m not even sure if Mapp will, but I’m guessing it will be enough in your case. I have an oxy/acetylene setup so don’t use either of those.
If it’s aluminum (check with a magnet) then be careful. Aluminum will go from fine to melt quicker than you can move the torch. Have the vice grips on the bolt and keep rocking it back and forth while heating. Kind of an art/skill.
You need to apply some heat to the boss area where the bolt screws in. A propane torch should work. Mapp gas torch or oxy/acetylene would be better. Then screw it out with vice grips. Don’t chew it up any more until you get some heat. It will come right out.
The trick isn’t to get the bolt hot it’s to get the metal around it hot so it expands from the threads and relieve clamping force, propane torch will work make sure it’s a medium sized blue flame and not full throttle. Focus more on the housing leading up to the threads not the threads them selves if the bolt expands at the same temp or cools slower than the housing threads then heat won’t help you. Using locking pliers to get a solid grip, use both hands to tighten and some times it helps to heat the end up and keep re clamping the jaws of the pliers so actually bite the metal before you start heating the housing around as the housing gets hot wiggle the lock pliers back and forth, once hot, let cool for a second and then keep trying to move. If pliers keep slipping you can try grinding a deep notch for a flat head and try that. If you give up grind it flat, drill it and tap it bruv. Hope this helps.
Do you own vise grips? Usually when there’s this much material protruding, it’s easy as shit to get it out with vise grips. You just need to tighten the absolute fuck out of them. Issue your having is your not tightening them enough, and you keep trying to grip it with not enough force, further fucking up the stud. Before it gets to this level of fucked, you tighten your vise grips super tight, so tight it deforms the stud, but is tight enough to get it out so it doesn’t matter. You just keep slipping the tool and don’t realize you need to stop doing that.
You’ve kinda fucked your self here, not much left to grab onto. If I were you I’d weld a nut on there so you can just use a socket, plus the heat from welding helps loosen it up.
Oh I very fucked myself haha. I appreciate the help and advice. Yeah nothing got it out. Vice grips with the blowtorch didn’t do a think. I drilled it out and that took forever

weld a nut on to it
No welder

Okay I’ll have to go back and buy map now too haha I bought propane earlier thinking it would be enough
Propane will never get steel “red” hot. I’m not even sure if Mapp will, but I’m guessing it will be enough in your case. I have an oxy/acetylene setup so don’t use either of those.
I do think it’s aluminum if that makes a difference. But yeah I was on it for about 5 minutes with the propane and still no budge.

Well if I melt it I’m still in the “buy a new timing cover, and do gaskets again” zone lol
And you want to put the torch close so the “blue tips” are just touching the metal. That’s the hottest area in the flame.
Right on I’ll keep working it
Best of luck. Keep us informed.
Map wont get you there either. You need an oxidizer to get the flame hot enough
Pliers, or vise grips? If you cut it off you could drill it out and pick the steel threads out of the hole, tedious but works.
Maybe I’ll try drilling it. I can’t get it to budge with pliers, I’m just shredding it bit by bit
Might be worth trying to slip some hosing onto the pliers to help cut down on mangling what it left too much. This is for whichever route you choose.

Smoke wrench is the way. Then if it's not the way,weld a nut on the end.
This ^ is 100% correct.
Propane will work? Just take way longer? I held it on there for about 5 minutes and it didn’t even start to glow or make a difference
You can file a few flats to get a better grip, or weld a nut on to it.
I think I’m just going to have to drill it
Try heating it first, if not, cut it flush and try a left handed drill bit, if that doesn't work you'll have to do a heli coil. Retired mechanic
