Lower motor mount dilemma

[DailyDriverMark]

When I was doing my clutch I decided to remove the lower motor mount from the frame -2 bolts-.

The first bolt snapped off.

I could not get the old bolt out of the frame so I put the mount back on using just one bolt. Well it's holding on, but wants to twist and rip away from the frame now.

Yesterday I tried to get the old bolt unfrozen and I didnt have any luck. I heated up the metal with a micro torch..
Tried a new set of vice grips on the small part of the bolt I can grab. But it's now too rounded off.

I can't get a drill straight onto the bolt to drill it out. What a pain! Next try, dremel tool, with cutting discs.

Or, maybe I'll just take it to a shop..

Broken off bolts are THE WORST! After having one on a recent project, I can feel your pain.

how much of the bolt is showing? if its more then a half inch grind it to where there are two flat sides spray some liquid wrench on that bitch and give it hell or grind it flush and drill it and re tap it.

If you still have enough of a nub, you might be able to cut a slot into it with a hacksaw blade, or any other cutting tool that can get into the space. If you can get that done, then lock onto a short screwdriver blade with a vise grip + something to keep solid pressure into the bolt while turning. First soak multiple time with LW, etc. and then also apply heat before trying to turn it out. If it doesn't want to move counter, then maybe try clockwise to break the bond, and be able to run more oil down the shaft.

If that can't be done or doesn't work, is there enough room to use a flexible drill extension to get a hole drilled into the bolt? I was able to do that on a WP bolt - real slow, and a PITA, but it did eventually work. For most of us amatures not having the specialized professional tools, broken bolts is the pits - good luck with it!

the easiest way to fix this is to get a nut and thread it on to the threads a little bit (even if it is too big) and the plug weld the nut to opening to the "stud" of the broken bolt, there by putting a new head on the bolt, typically the heat from the welder will free up most of the rust and such as well..

but it only works is if you have a welder.

Awesome replies thanks!!!... exactly the thoughts that have been mulling thru my head..

The good news is, there is enough sticking out. I'm going to dremel some flat sides onto it, and maybe try a set of ez out sockets. unless the vise grips, will grip again.

When I buy a new bolt...anyone know the thread size? Looks metric to me.

i wouldn't use a vise grips it sounds weird but grind down enough to get a crescent wrench or an open ended wrench or your just going to round it off again and as far a bolt match up take the bolt you did take out and go to a hardware store to get the right one but if you have to drill it you can put a similar size
