Fixing Bolt Holes With No Threads, Stripped Threads & Really Crooked Threads

In a previous video ( • Removing Broken Manifo... ) we removed some broken bolts from the head of this Chevrolet 2500 6.0 using the welder. Unfortunately someone was there before us and made a big ol mess of this head. Now it is time to show you how to (hopefully) recover the hole(s) and use some thread inserts to make the repair.

Lots of choices out there for thread repair kits on the web. Personally I have used Time-Sert (The best IMO) and I have used a LOT of Helicoil brand and have had great luck with them as well. I see a lot of off brands on Amazon that have really good reviews too. Do your research, take your time then just get after it!

Back seating a thread is what ive learned with building computers. Was always scared of cross threads etc. with these tiny expensive fers. So one day on a tech channel a guy mentioned it and it's erased my cross threading fears I've had all my life.

[@AdmissionGaming]

What is back seating???

[@SourBogBubble]

@@AdmissionGaming so add the screw to said threaded hole. Now rotate the screw backwards until u hear an Audible click(Very noticeable even on the tiniest of screws) you are now fully seated in the thread, no more cross threads. 😎🤙🦅

[@rickwoods5384]

I was taught to do this by my mechanic father. One day picking up parts at the NAPA counter, I was checking the fit of new part to mating part that I had brought along and of course starting rotating it ccw to find the start of the thread. The men behind the counter had a good laugh thinking that I did not know the correct righty tighty rotation. I attempted to explain, but they were laughing too hard to hear what I was saying.

[@raypeoples]

The ingenuity,craftsmanship,patience, labor involved in this repair was worth more than the vehicle, imo!!

[@gungadinn]

For holes that are really buggered up that have previously had a Heli-Coil installed, you can drill an over sized hole for a Keensert. It's about 25% larger in diameter than a Heli-Coil. Instead of a spiral of wire, it's a solid metal plug with threads. Provided you have straight access, use a "ShotGlass" which sits flush with the surface and takes a removable drill bushing. For LS engines, I made a drill plate of half inch ground stock which bolts to existing good threads. There are removable drill bushings which act like the ShotGlass, but allows the use of a right angle drill. Normally I'd use Jig Plate, but I'd have to cut and machine it square, verses ground stock that is ready to use. I suppose I'm going to make one of the plates for the 5.7, 6.2, and 6.4 liter Hemi engines, as my next truck is going to be Hemi powered.

[@daveh7587]

Then you can pull the head anyways when (not if) you have to put new lifters and a cam in it. 🤦‍♂

If Eric was a MMA fighter, he would be in the UFC and be in the top 5, probably a champ. He’s so well rounded as a mechanic. In the beginning I wondered if him not being a car guy was a minus, but I think that gives him more of a advantage than disadvantage. I swear I learn something in every video, and I watch every video. I enjoy when E get’s on a “let’s see how many people we can upset” roll. I also dig the quotes and all the commentary….“Enhance, enhance”, “There’s your problem Lady”, honk…”hey, it’s that guy”, “push, push, push” Years ago when I found this channel, I remember liking how he ended the videos…”Remember viewers, If I can do it, you can do it”. For some reason that really resonated. I knew after the first video, if I was working on my vehicle, I would find a SMA video on it and watch it before and during my work. I’ve not just learned about automotive withe SMA, Eric is good people and there is ALWAYS things to learn from good people.

[@thefretfiend]

When I was a mechanic in a Norton motorcycle dealership, I disassembled a lot of Norton motorcycle engines. All the threaded holes on the aluminum engine components had helicoils already installed. They came that way from the factory. Helicoils are much better than aluminum threads.

[@johnz8210]

That was great, thanks. Remember the Mopar 318's that the end studs went into the coolant passage? I think the first time somebody does one of those there's a WTF moment.

I left the Michigan rust belt 43 years ago for a variety of reasons. Watching SMA videos reminds me of one of those reasons.

[@tiredoldmechanic1791]

As "the guy" who got to do the thread repairs, this was an excellent tutorial. So many people don't break off the installation tang. I have to point out the importance of using genuine "Heli-Coil" brand, or at least it used to be. The brand name has probably been sold and the kits cheapened by now. The original kits included the drill and a bottoming style tap, both of which were quality steel and an installation tool that has full threads. The cheap knock off sets often don't include a drill which is often an odd size that people don't normally have. It needs to be a quality drill because you don't want to break it off in the hole. The cheap sets often have a tap that is tapered too far down so the threads aren't full to the bottom of the hole. They include an installation tool that isn't threaded so the coil will screw into the tapered hole then the bolt wedges when it is installed. I've used those kits because many places just carry the cheap kits. I've ground the tapered end so I could get the threads to full depth. Usually the taps with the cheap kits will dull quickly and you can only use them to install the number of inserts that came with the kit.

[@Fjord_Driver]

Fixed mine many moons ago now. 2001 F150. Used a metal plate drill guide setup. Had to get short drill bits in order to fit in the space. Didn't have a welder, but a mini torch and some solder for a stud sticking partly out. Filled that nut with solder. Bashed the crap out of it with a hammer to flatten the solder pile as much as possible to jam it into the nut threads. Worked. Installed US made stainless studs and nuts with nickel anti-seize. No problems since. And new OEM Ferd exhaust gaskets. I can't say it was a fun job. But I can say if I never get the chance to do it again, I won't be sad.

Thanks for the video! Today I spent a couple hundred bucks on a m10x1 Time-sert spark plug insert kit because Stihl is now using the smaller spark plugs. I was afraid to just buy the helicoil kit. The time-sert has a starter tap for the blown threads then it shelves to m12, the insert size. The arborist company owner asked me how a saw could spit out a plug. It's always fun telling an equipment owner that someone removed the plug and didn't retighten it. It is doubtful that I'll ever recover the tooling cost as the govt forces battery equipment down our throats.

[@bobhudson6659]

Not bad. You did well. There are other larger OD forms of insert which recover the hole even better but then they are significantly more expensive and time consuming. As you indicated this repair will outlast the rest of the truck. You might also consider 2D and 3D helicoils instead of the standard 1.5D helicoils, with longer bolts, if the start of the hole has been chowdered out. Look up what 2D and 3D means if you (and viewers) are not sure what that means. Retired mechanic/machinist in Land Down Under.

[@mattmanyam]

1.5 x (bolt diameter) 2 x (bolt diameter) 3 x (bolt diameter) Once you reach 1.5x bolt diameter (for any fastener), the surface area of thread engagement is greater than the cross-sectional area of the bolt, and should (in theory) be stronger than the bolt. As loose as helicoil fit is, this is less true, because the loose fit means there's less surface area engaged on the threads. 99.9% of the time, 1.5d inserts will be plenty sufficient.

[@wornoutwrench8128]

Where would us mechanics be without thread inserts. Saved my a$$ many times. When I was just starting my career wrenching had to drill out a manifold stud on an old Detroit Diesel. Can't remember what series it was but when the drill went through the end of the stud, antifreeze came pouring out of the hole. I thought I had drilled into the water jacket. Turns out, some of the studs were open on the back to the antifreeze. Hell of a surprise, hell of a surprise.

[@andrewgilbreath1331]

That brought back a flood of memories from when Rebuilt a old yamaha boat motor, I went to take out the the bolts for the thermostat and snapped off 1 of 2, which then meant I had to remove the exhaust side cover to drill out the 1 bolt, because it went through the stat and exhaust cover, only problem was the side cover had 21 bolts and 14 of the 21 were seized and broke off I spent quit a few afternoons drilling, tapping and installing helicoils. Was the first time I had ever done that and it went well, but man it was quite daunting at first I learned very quickly that a center punch and slow and steady were my best friends in that case.

Nice work. I seen an interesting video about thread repair where even if the threads for the HeliCoil were too far gone it can still be repaired. He had bored out the hole large enough to tap threads for a bolt wide enough to tap the original size threads into the bolt itself. He added two small punch marks into the threads so it was not easy to thread into the hole and added thread locker to ensure the bolt would stay after installation. The bolt head was cut off flush, filling the hole. The center punch and pilot hole were next before boring the correct size to be tapped into the newly installed material. It seems to be a lot to go through and getting the correct angle may be challenging by hand but I thought it was interesting. Have a good one :)
