There is a young machinist in Clovis NM that does this on a regular basis. I have watched him do a few and as scarry as it sounds it works and works real well. I've tried it a few times and it all has to do with how hot you get the bolt and how fast and hard you hit the cutting lever to blow it out.

The key word in thst torch story being "young. " Sorta like when you look at tree crews, ever notice they're all young ?

I Used To Have An Old 6. 5 That The Starter Bolts Would Break Off In The Block And I Got Quite Good At Removing Them. I Used Left Handed Bit About 1/2 To 2/3 The Diameter Of The Bolt. The Other Trick I Learned Was To Use One Of The Cordless Drills That Had A High Torque Seting For Screw Driving. It Would Normaly Come Out Before I Drilled A 1/4 Inch In. I Used The Same Tech Last Week On An Exaust Manifold Bold On A 1066 International Tractor. I Did Soak It With Pb Plaster Overnight. I Would Bet Your Biggest Chalange Is Going To Working Room Under The Hood.

If the bolt is broken off fairly square, use a bit that just fits down the hole just enough to make a center depression. Then use the smaller bit.

You've been given a lot of good advice. Here is what I did just yesterday with a broken spring bolt on a '68 W300. The bolt broke off flush with the surface of the spring perch on the front axle housing. I took a 4 1/2" grinder with a very thin cutting wheel held vertically over the top of the bolt. I lowered it into the bolt and cut a slot that would allow a substantial screw driver to fit. Then I heated the bolt with my torch until it was bright red, held a piece of paraffin wax on the surface, sprayed it with PB Blaster, and then let the whole thing cool down. After a while I took a small chisel and tapped on the slot in a counter clockwise direction until it moved slightly. Then I put the screw driver in and screwed the bolt out. It was extremely easy.

I would do that but it s broke off about a . 25 in to the head and it is the very back cylinder but thanks for the idea anyway

Too bad. It sounds like the drilling process. It might be good to have a magnet around to collect the shavings so they don't go where they shouldn't go. JH
