People who have never gone to war with broken bolts will never understand the satisfaction of victory. Knowledge is knowing how to remove broken bolts and wisdom is knowing which method to use in the different situations.

[@geodun]

For sure and imagine how cool it must be for the engine owner to see the rebuild being done step by step. It must also add value if the vehicle if sold in the future. No need to tell buyers what was done to the engine, you can show them.

I'm 70 years old too and I have all the same problems you observed with the block in the first 5 minutes of this vid. Similarly, I plan to just keep running as long as I can 'cause I can't find any spares either! I hope they give me a shot of something when they start using tools on me.

[@marcusw86]

This guy reminds me so much of my uncle, when he was still with us. He brings me plenty of good memories.

[@Alaska_Engineer]

I’ve had a few of these F-heads, hot rodded one 25 years ago that I still drive. 72hp up to maybe 100 is a huge difference! Really glad the owner elected to save this block. I run 100% glycol specifically for rust prevention and it works awesome. He should be fine with 100% and some good block sealer. I did make a torque plate years ago, and it helps a lot to run hot water in the block when you bore & hone it. I circulated hot water from a small electric hot water tank. WAY over the top, but I was doing all my own work and not paying a shop rate. Really nice work as always!! That owner chose wisely to take it to you!!

[@zacharysanchez4375]

I felt that when Jim said “I’m having trouble keeping track of my tools lately”😂😂 story of my life

You guys have turned broken bolt removal into an art form. Thank you for another outstanding video 👍🏻

[@Smittyschainsaws]

I’m getting more addicted to your videos everyday. I’ve been building hot rod 2 stroke engines but I’m just learning about machine work. I just picked up an old Pennsylvania Railroad lathe that I need to learn how to learn how to fix some of the sloppiness of it. It’s not horrible but just enough to make it a pain if you know what I mean.

[@SightsNjunk]

Have you guys ever used left hand drill bits on broken bolts? Being from the rust belt (Michigan) I always keep a set on hand. Lots of times, just as it's about to break through, it catches the end of the bolt and backs them right out. I have about a 70% success rate. I even use the cheapies from Harbor Freight....they work well.

[@Livedracersteve]

I was going to suggest this myself, left handed drills are great, once you thin out the bolt it tends to collapse from the thread and pull the bolt right out.

[@Jonathan-hx6oy]

I'll third this, coming from a mechanic job that uses lots of bolts under high stress high corrosive, where bolts sheer of a set of Carbide left hand twist is expensive but makes removing broken bolts WAY easier. Like first guy said 70%-80% of the time before you get to max size broken remnant will screw itself out before you get to tap stage of process.

[@machinist7230]

They mostly use the welded on nut method, which works about 98% of the time.

[@Jonathan-hx6oy]

@@machinist7230 no, crap. We're talking for when they're usual method don't work. A helpful alternative to the current method.

[@johnlaforce4421]

I have a set of Left handed Cobalt drill bits that work well for broken bolt removal, a lot of the time the bolt will spin out just as your ready to drill completely through. The drill bits have paid for themselves many times over.

I’ll likely install new rings, valve guides and possibly new valves and rebuild the oil pump. Sure can’t achieve your level of sophistication and accuracy, but it should survive well past my lifetime and give my grandkids much enjoyment on our Montana forest service roads!

[@srgraham9172]

I wonder if “The Cleaning Guy” ever thought he would be a KZbin star? 😂

[@redmondjp]

Compared to the level of precision used when this engine was originally made, this is a perfect example of blueprinting - this engine will run tighter and smoother than it ever did right out of the factory! Excellent video, showing how much judgement is necessary and all of the decisions that have to be made along the way, stuff you just don't learn from reading a book on how to rebuild an engine. I took machine shop class and automotive shop in high school, and we did have an entire small room dedicated to heads/valve grinding, but didn't have the big equipment for doing the blocks. I really hope and believe that videos like this will inform and inspire a new generation of machinists that keep this critical skillset alive moving forward!

When experiencing fastened bolts like your two broken ones, I usually use a screw extractor. (The cone bolt with left threads) I love those old engines as I appreciate your channel. Carl

[@tinkmarshino]

I truly enjoy this channel.. I was an old gear head from the 60's on ward and have always love to build cars.. But Alas my body has finally betrayed me and I had to stop about 4 years ago.. In all of the fun I have had I never got around to doing machining though I always wanted to.. But seeing how this was a kind of hobby (I was a builder and a wood worker) I never got to go that far.. This is so relaxing and enjoyable I still want to do it.. But my memory is also going by the way side also.. not that I am complaining mind you I have had a great life.. I just wanted to say thanks for the enjoyment my friends.. Carry on!

We used JB weld on holes like that, then sanded until smooth. we then installed the cylinder sleeves. it worked good

[@mwrcrft]

When that Jeep was new in late 1940's early 1950s a motor only lasted 50,000 to 80,000 miles before rebuild. Motor oil was so bad that they generally smoked after 40k.

[@JRattheranch]

After at least 2 de- cokes as well!

[@Cougracer67]

As you may already know, if a bolt hole opens into the water jacket you can drill out the center of the bolt clear through into the water jacket, then burn the bolt out with the torch. With an open hole, the crumbs will blow right on through. Get the shell of the bolt red hot, then hit the oxygen lever and stay on it until all the remnants of the bolt are burned out of the bolt hole. The rust/crud in the bolt hole threads serves as insulation so the cast iron threads do not get red hot and thus are protected. All you need is a thread chaser to clean out the crumbs and you are left with an undamaged threaded hole ready for a new bolt/stud.

[@nathanwrobel5534]

You guys are great, really enjoying your videos. I have a valve grinder, a stone seat grinder set, and a forklift that runs terrible. I’m going to give my first head rebuild a shot.

[@garytarpley3771]

While working on medical equipment at Houston Hospital outside Texas Medical Center in 1990 I was presented with IV pump with damaged drive head a Stainless shaft with a Stainless broken headed screw needed attention.There was a tiny curl of threaded screw above the shaft with the screw head snapped off .I had no materials to work stainless;I used a pair of flush cut diagonal wire cutters ;holding the thread of the screw I was able to back the damaged screw out; the flush cutters allowed me to reach the thread of metal outside the drive shaft. MY coworkers were surprised I could remove the broken screw; You have to have some Luck;hard work plus some Luck

1:28 "no seat at all" yes I agree (with previous re-builder) because valve seats do fall out, so the fewer the better.

I don't think that sleeve would ever leak however a block filler ( we used yrs ago for truck pulling engines) could be used probably at 3/4 inch would ease your mind.

[@drussell_]

That's exactly what I was going to say... Put a little block filler at the bottom of that water jacket as insurance. They'll all be thin there.

[@chengkuye]

A pleasure to watch an expert. Thanks

[@rpujol]

Great video as always. I did rebuild a lot of this L-134 and F-134 Jeep engines here in Spain coming from military auctions. I agree with the cleaning guy, the torque plate honing is a boomer thing, for 100 years engines have been honed without it and engines ran fine without any problem. Only thing I would have done is to change the remaining 3 exhaust valve seats and install hardened ones as the one in #1 cylinder, just to be safe for the modern unleaded gas. For the rest, always top notch service and machining job. 👍🏻👍🏻

Thanks for another absolutely amazing video Jim!!!!! It was extremely informative and ever so interesting and entertaining!!!! My compliments to you Jim for the fantastic job you have done on this 73 year old engine and block and head. You used what I refer to as the old ways and watching you work was an honor. You got the touch and I respect your work. So glad I found your channel. I personally think this engine is going to run just fine when put all together again. The owner is so fortunate to have you doing his engine. Those small spots in that one cylinder I believe will be just fine the way you did it and the time you took to redo it. I like your comments about taking your time and using patience!!!!! That makes a huge difference in this kind of work. Loved watching you get those broken off studs out. You are a master at that. I have tried over the years and I always made a mess of it. So watching you was a pleasure plus I learned a lot by watching your work. Well guess that is it for now. Throughly enjoyed this video. Thanks for everything Jim. You take care. Looking forward to the next video on the Jeep engine. My best regards always. The retired Air Force veteran.

[@petewade7750]

Love your videos! As a machinist and balancer, I really enjoy seeing how things are done in the automotive world. Question: have you ever thought of a “shop tour” video? Do you have your shop organized so that you just move around from machine to machine in the order needed for a rebuild, or is more random? What is the scar on Jim’s right forearm, Engine work, or farming work? Have you looked into a tap buster for removing broken studs? Have you ever tried metallizing to repair worn cranks and cylinders? Does the cylinder hone machine wiggling as it’s stroking up and down affect the cylinder bore straightness? Can’t wait for the next Willys engine video!

[@JAMSIONLINE]

That's a lot of questions. I'll answer some of them. Check out some of our older videos as we have done some shop tours in the past. The shop is organized so the cleaning equipment is together, the head machines are somewhat together, and the cylinder machines are close together. Then we have the rod machine close to the block area as sometimes you can work on rods while the block is being bored or decked. The crank grinder is by itself as it requires 100% of the attention of the operator. The wiggling of the hone is only the driveshaft that has a u-joint on each end. The hone itself is centered by brass shoes that ride the cylinder wall. The scar on my arm??? That is from a shower towel hook I hit with my arm while throwing my towel up over the shower rod so it would dry. Farming and the machine shop are not nearly this dangerous.

[@petewade7750]

@@JAMSIONLINE Thanks for the response! I'll have to look deeper into your videos and find the shop tours. I just noticed the scar and figured it was a cool industrial accident story. Oh well, HAHA!! I've really been enjoying watching your videos, especially the balancing. My Dad and grandfather never wanted to get into crank balancing, and I never understood why, we get asked often enough. Seeing you and your son do it has gotten me interested in it. Other than all the math involved in the piston/rod weighing, the balancing is nearly identical to what we already do. We'll see, maybe one day. Thanks again, you guys are doing awesome work!!!

[@thisoldjeepcj5]

Amazing work, invaluable experience, great video. Thanks for sharing your knowledge and skills.

[@dans_Learning_Curve]

On removing broken bolts, have you considered taking a torch and heating up the bolt to red hot before welding the nut on? I believe the heat from the welding does the most of the work of getting them loose. The nut is just the connection to the broken bolt.

I have also at times had to drill them and I tried a trick my dad showed be and that is using a reverse threat tap and bolt to basically turn the threads themself out. What I think makes this work is the fact you already have used every other thing in your toolbox and there for have loosened it already quite a bit this is not something you wanna try first. another thing that works really well is just walking away from it. sometimes you get so focused that nothing you do will help but going to bed and coming back in the morning works great for some reason. that goes for alot of shit that is going wrong on something your working on! it has gotten so bad now my wife hears me cussing at something she will tell me come on lets go to bed!!
