Kenny a proper old school mechanic , but also knows his way around electrics and computer diagnostics
Thank you for your kind words & for watching the channel. Keep wrenching 🔧
Well, saved the customer money, and fixed what should not have been broken in the first place. But you taught all of us how to use those inserts properly, and also tricks on how to use them as well.
U will be surprised how some places charge for something like this might be over the price of a new head
If that head was not repairable, I would have pulled the other and done a valve job, unless the thing had tons of miles on it. Then it would be finding a set at a wrecker yard. Yikes@@whiskeyfamily6717
That is why you use anti seize on plug threads
Great job Kenny, I love these kind of repairs it's the oldschool mechanic magic
BS!
It amazes me when people botch things up, you know when a spark plug is on the wrong thread still creates work for someone. Another great video Kenny.
Your a good man SIR! I'm glad to see you could help them instead of sell them another cyl head.. or send off to a machine shop...
"First, do no harm!" I have a short handle Snap-On ratchet I have had in my tool box for years. It is great for installing spark plugs and not over torquing them. I am amazed at the 80 foot pounds people put on a spark plug.
Yeah, they superman tighten them, so when you go to pull one out, it's a nightmare.
@@jthonn same with 10mm valve cover bolts. No wonder the valve covers leak. Of course the modern cars with plastic crap everywhere make over torqued bolts a real issue.
Years ago, I had an Escort that had to have the spark plug threads repaired. My local machine shop put an insert in from the valve side stopping right at the taper surface so that the original type plug would still seal. He somehow locked in the insert to where it would resist coming loose while installing the plug, but the taper seat would not let it come out while removing the plug. The repair gave no problems for as long as I knew the car's history. Thanks Kenny, for showing DYIers how to avoid making common mistakes.
After the repair Kenny made, I am almost positive original type plugs will work fine. He fixed it right.
I learnt very early on, hand fit everything threaded before using a wrench or gun, especially spark plugs etc. If you have to use a socket to run it in, still do it by hand, saves a lot of time because you don’t go wrong.
And old airplane mechanic told me you can't cross thread anything by hand. If it doesn't turn in by hand fix what's wrong.
That makes good sense.
Leaned that early on too .. early teens. Was told to always use your hands when putting a plug in. that was After i fucked the head on the mower. a good life lesson. cheers.
Glad you showed the red scotch bright. I bought the green. Didn't know there was a red very fine. Thanks Kenny!
Dude, this is great! I have always let the machinist handle this type of situation but I love seeing how it is done.
Nice work Kenny saving that head. A shame it had to go that far, but at least it's fixed.
I can’t get enough of your videos. Love the content. Thanks
Appreciate it! Thanks for watching
Hey there brother Kenny, this was a great video. You did an incredible job for your customer!
I am super impressed especially as an old timer that has used Heli-Coils. There's no room to fix threads in van and I would have thought head was junk. ALL of Kenny's thoughts and procedures I know are correct right down to Red Threadlocker. Excellent save and I learned a bunch from Kenny. Been following this true mechanic and now a faithful subscriber.
I agree@@jefffrayer8238
Nothing is more fun than fixing threads that are messed up!
As a former tech, I am amazed at some of the "butchers". You almost have to work at it to cross thread a plug. We had a saying back in the day when encountering priorly cross threaded items accomplished by hacks, their motto must be "cross threaded is better than no threaded!"😅😉
The correct term is crossthreded is better than lock tight
Impact wrench hacks best friend. I'm sick of fools on UA-cam using power tools on aluminum and plastic.
What a great and informative video, thank you for taking the time to record and explain what you're doing!
You're welcome! Thanks for watching🔧
Another great job and saved your customer! Thanks Kenny
Good save right there, glad you shared it very interesting 👍
A fine job ,especially the shop made tools.
A true engineer! not a mechanic or fitter. Great work
Great video Kenny. Thanks for sharing. I always learn something new from your videos. Cheers.
Time-Sert makes a very nice kit to repair these permanently. I have used the kit extensively on Triton engines that blow the plug out.
I understand your frustration. I used to come home from working on machine tools. And sound like you talking to my wife. I was told by her " shut up, thats how you make a living. Fixing break down weather it's neglecte or stupidity."
Very good video, thanks Kenny for all the knowledge you give out, blessings for a good week.😎☮️✌️✅
That's why I carry multiple spark plug or regular deep sockets of the same size. Some are deeper than others or a little shorter to clear something or have a thinner wall to fit where they have to. Great video, very informative and detailed.
70k Kenny! Good channel! Always quality content!
I’ve learned so much from your videos, I and everyone that watches your videos appreciate you for teaching us the correct way to do the work we thought we knew we could do. .👍yes 👍👍👍👍keep up the great work and the videos . Yes yes job well done.
Glad to hear it! I really enjoy sharing what I know. Thanks for watching and keep wrenchin 🔧🔧
I paid 100$ for an install kit that has 1 of each length, the installer, and the peener. It works generally flawlessly. Being a Ford owner with a gen1 5.4 2 valve i have used my kit on my truck as well as customers 4.6 trucks. Having to do that on a Chevy is a rare occurrence.
Great job patience and enguinuity
I’m about to embark on a journey that I should have taken decades ago, I’m going to train to become a certified master mechanic/ technician. Since watching your videos, I will have a wide open calm mindset to help me deal with difficult situations.
Good luck I hope it goes well for you
God speed on your adventure mate.
Wear a chemical respirator, paint spray mask, VOC filter when dealing with gas, carb cleaner, solvents…I worked in a machine shop that did all the work for the city bus system. Everyone else’s hands shook constantly from the solvents. I’m 6 months away from my 70th birthday, and mine don’t shake. Same with dust, cars get nasty dust all over everything. Better to learn about electric cars, not even close in the amount of poisonous substances used to work on them, or manufacture them either. Use your head, save your lungs and brain for family and friends. The full on respirator with the chemical canister filters, nothing less my friend. To hell with those that laugh at you, all those guys at the shop are dead now….
@@5400bowen > Better to learn about electric cars, not even close in the amount of poisonous substances used to work on them, or manufacture them either.
Only chemicals not present in an electric car but present in a gas car are engine oil and fuel. Still have coolant, gear oils, refrigerants, brake fluid, brake dust, and road grime, and it's all basically the same formulas. Oh and arc flash hazard as a bonus, so get your arc flash PPE too.
@@treelineresearch3387 I worked in a machine shop…gasoline and motor oil are used in massive quantities daily. Those other fluids are maintenance items that use about 1/10,000 as much volume, and are not nearly as bad as gasoline. How much brake fluid, coolant, transmission fluid and AC coolant do you think the world goes through in a year? And how much gas and oil in that same year? Gasoline cars catch on fire all the time, electric cars (a brand new technology competing with century old one) don’t catch fire any more than gas cars, and gasoline fires are just as bad. Rolling Molotov cocktails is what they are. Then there is the exhaust…Elecyric cars use less than half as much gear oil because their transmissions are 1/20 as complicated and large as a ICE car. The entire engine/transmission/ final drive of an electric vehicle is about the size of the entire engine in an ICE. And no noise, or exhaust….
Lock n stitch are by far the best thread repair kits available
Looks like you got it figured out. Great work.
Awesome work, thank you for showing the fixes. I use red scotch bright with some wd-40 for cleaning up aluminum heads.
Excellent video! I hope I never need any of these thread inserts, but it's nice to know they exist.
There is NO SUCH THING as COMMON SENSE. If Sense was Common, everyone would have it!!!😉
Good point
Good job Kenny! You're the man!
It sounds like the previous mechanic didn't peen out the knurled end enough once he was at the correct depth. Then when he turned the new plug into place, the whole insert spun itself deeper into the cylinder. With a plug design that is smaller than the big threaded hole for the insert, there was no increase in torque telling the mechanic he was done. This was by far your best video for me, I had no idea there are special plugs for this exact situation. If I ever find a plug like this in a car, it will be a clue that tells a longer story. And you gave me something more to worry about, if a valve is open when doing this. It means an extra step of finding TDC compression, and then moving 1/3 turn more to get almost to BDC on the compression stroke.
Not a mechanic. 😅
Those plugs he used to install were different that the new plugs he put in. Once he fixed that mess, he could put the factory like plugs back in.
@@jthonn That's a good point, I wondered about that. So, we're relying on the locktite and the extra effort to peen the insert so that the new slim plug doesn't spin the insert when it is torqued down.... That might even happen at the next plug change.
I hate to say it, but that thing I don't think will last to the next plug change.@@spelunkerd
Others chiming in for a different repair kit, Time serts?
@WrenchingWithKenny Just a helpful note for your viewers. Best practice is to use time-sert Kit 4412E-187 or similar from other manufactures specifically for tapered seats (gasket plug is a different insert part number) good mention about thread locker high temp Permatex, Loctite or Time-Sert p/n 6020 Locker & Sealer specifically high temp for spark plugs inserts as you show. Most techs will use regular thread locker, and this will burn out. This time-sert kit does not have the extra thick wall insert the Chinese kits do and will leave a thick aluminum cover over the insert inside the combustion chamber. On LS heads A lot of techs do not understand you should not go double oversize (Chinese inserts) on a LS cylinder head. The aluminum around the insert gets to thin and will not dissipate heat from the fast enough correctly. When this happens, the aluminum will literally melt away at the insert because the insert retains to much heat. Great video. I usually do not have may positive things to say about repair videos, but you nailed this one.
Still HIGHLY recommend using time-sert as they have a "thread roller for straightening out slightly damaged threads
Yes. The timeserts are quite good. The steel inserts like in the video are junk.
Thanks for the video!
anybody else yelling at the screen "Lube it!!" ??? LOL
BTW i have the same Snapon flex head (metal handle) and love it. At this point it is over 30 years old and is still my GOTO
My grandpa had motor mounts done on his Astro. The "mechanic" welded them to the frame instead of taking the time to install the 3 bolts.
I wish the tool manufacturer put the part number for the two types of spark plugs you used. I just repaired my ford escape, the plugs are 7 inches down the hole with the twin over-head cam engine. And of course it was one of the back against the firewall plugs that blew out. Great video, wish I had seen it before my repair.
I have been fixing cars etc for 37 years and have repaired plenty of plug threads with heli coils I have never had a issue ...just be careful the tang don't drop down cylinder when you break it off
I like this kind of vid. Thx Kenny.
Nice job on the insert. Ran a machine shop for many years and i always used red Loctite on them,none ever came back.
Kenny. If you ever see the cheap tool kits that come with motorcycles, they’ll be a cheesy spark plug tool formed out of thin wall tubing that will fit down even the narrowest plug well. Providing you find the right size, it would be worth having them for this instance. They’re about a buck at a swap meet.
Epic save!
I've had problems with the Helicoil insert with the knurl. Came back out next time I removed the plug. Much prefer Time-serts they have a positive stop and won't thread further into the hole.
What a mess. Head is off, replace the head and move on with life. That was a nice repair though.
Amazing work
Interesting to see the insert being peined with a hammer the head sitting metal on metal on the work bench. The head made quite the sound when being dragged across the bench. A towel between each next time perhaps?.
Modern engines the cylinder head ( If not the whole engine ) is alloy, it is softer than say cast iron, cross thread a spark plug and you are in TROUBLE!! Which is why my my garage will be changing mine, to Avoid a HUGE bill!!
Thank you, very informative information
and interesting content. Thanks again
Kenny; 4:49, If I'm not mistaken, that's an intake valve.
Everybody has to learn.
!
😅 . I'm sorry man. It just caught me.
Not saying I've not done some stuff back in the day. But some of these are mind blowing.
Doing a great job. Thanks for the vids.
Great job
Time sert have inserts for taperseat plugs excellent repair system
Another commonsense repair, thank you. I also saw that the back cylinder has a common LS problem also, broken exhaust manifold hold down bolt, I assume you fixed that also.
As always Kenny very professional job there the shade tree mechanic that did the previous work should have all his tools confiscated and never given back to him or her ! Great job Kenny ! Stay Safe! 👍👍
Well, I wouldn't use the term shade tree, I would simply say idiot.
@@jthonn Well I was being nice but yea that sums the person up very well
Yeah that was kind of ugly, sorry@@victorjeffers1993
As a retired carpenter ...every guy is a virtue signaling liar that can pick apart the last guy's shady work and cover it up with even shadier work.
Send one on a call-back and it gets crazy. Can't say the last guy was an idiot because it is him.
I agree, if I understand you correctly. When things are totally wrong and every job is botched, like this one, turn in your wrenches. Can't even install plugs without stripping them out, or splicing wires like a third grader. No offence to the third grader, because when I was a third grader, I guaranty I would have done better than that.@@mikeries8549
Looks like you're working on a GM minivan. Go through the wheel wells to gain access to the plugs. Especially the ones near the firewall. # 5 and 6. Drivers side,you gotta fumble with steering gear and brake lines. Passenger side,not to bad. You do gotta pull the wheels.
Nice video, I can see why you get 10,000 views a day.
With regard to the previous repair attempt, in the words of comedian, Jeff Foxworthy, you can’t fix stupid! Very good repair, although I would have loved to see some type of cushion between the deck of the cylinder, head and your workbench as you were painting the top of the insert
Great job, i do the same way, but i use bearing mount.(should never come back out😅)
From experience, if a HELICOIL backs out, it is due to improper installation. The ends must be a minimum of one full thread deep for full contact so the end will dig into the thread when turning. Loctite is never used on a HELICOIL. I have seen quite a few that were installed with the bottom tang not broken off which is supposed to lock the thread when installing the bolt or spark plug. Also, on blind holes, if the insert is too long, it will begin to become a smaller thread at the bottom because the tap has a taper and when a long bolt is installed, it can cause the insert to back out when removing that bolt and it will lock into that taper portion giving incorrect torque. My old boss used to say to me that only 2 threads of an insert are needed to fully torque a bolt. That would be for me a do or die situation as I would want the proper length per bolt for security. I have always used HELICOIL. They were designed for aluminum threads I believe during WWII but I may be off about the exact time. I have never heard of an airframe failing due to one being installed. In my old guard unit, we had a massive genuine HELICOIL installation kit and it included go/no go gauges. You don't see that anymore. This may probably the reason they were allowed. Funny, I have never seen the actual instruction book that came with that kit but it covered just about any thread used in America. Only Uncle Sam could have afforded it.
Standard Helicoils aren’t pressure tight. Locktite is a thread sealant (but water glass (sodium silicate) or RTV would be better for high temperatures).
You seriously have to watch some of these shops. I had a transmission that was starting to slip. So I changed it out for another one from the wrecking yard. The core I was offered at the wrecking yard was a joke. So I took my transmission to a rebuild shop. The service writer (Mike) refused to give me a quote. Saying that I need to leave the whole truck with him. As HE has to be the one to remove the transmission, rebuild it, and reinstall it. Only after I pressed him. He explained that the manufacturer may have put "the wrong transmission" in my truck to begin with (a truck that ran perfectly for 26 years). As well. I may have "improperly installed the wrong transmission from the wrecking yard," and he doesn't want to take "responsibility for any mistakes I may have made." The same (2nd) transmission that I was going to also have this fool rebuild. When all was said and done. I ended up rebuilding both transmissions myself. Watch yourselves out there, guys. There are a lot of slippery shops!
Hi Kenny! Good work!
There are threaded sleeves with a lip/flange at the top to stop the insert in the right place. Any views on this type? Many thanks!
Needing to make a repair is bad to begin with, but that's just how it goes. Needing to make a repair as a follow-up on a botched repair is a royal pain. 🙄
Just an FYI for when you order more scotchbtite pads, the 7448 (lt grey) is a bit less aggressive than the 7447 (maroon), or the 7447 pro pads your using. I couldn't tell if you were showing the pro pad or the regular 7447. The 7448 are about equivalent to the green sponge pads sold in grocery stores. And the 7440 ones work great for cleaning up the bead areas on cast rims when installing tires.
In residential house construction we call this job the high cost of cheap construction. The customer tried to hire a cheap mechanic will end up paying four times the cost in the long run. Ouch 😮
So soothing
Holy crap! How many shops would have pulled that turd out of the garage asap and told the customer good luck.
I'm surprised that the customer approved for Kenny to fix it... Trust in that shop now that he's showing the failure of the previous tech that touched it 😢
This shop Kenny is working with will now be the go-to shop in the area for trustworthy repairs 😮
Other shops that's up and coming should follow this if they want to get some word of mouth type of deal instead of advertising
I know a few shops who never have to advertise and they're always busy
Great spark plug fix video. The only thing I would recommend is considering “Joe X, the Rag Man” mechanic did this type of damage with these spark plugs, I would have the head X-Rayed for cracks in the combustion area of the head. Personal experience I had a crack when I did the exact repair you did.
Not sure that old van was worth all of that, if it was you could just replace the heads.
You are 100%right👍🏻👍🏻👍🏻👍🏻
How does someone cross thread an LS cylinder head. That’s wild maybe a ford 😂😂
I would be concerned that the rough edge where that sleeve was in the spark plug hole would create a hotspot and cause predetonation. Just a thought.
possibly, but I think he is alright, I would have just smoothed it out a bit, not that it really matters
Once again always hand thread a spark plug at first to make sure it's threading right. You can tell if it's cross threaded. If it is stop and take it out and try again. Turn it counter clockwise until is drops down to the threads and you should be able to tighten it correctly and not cross thread.
By the time you're done repairing this hacked van, the owner is going to spend more than the van is worth.
Nice to see someone still fix something now days. doesn't happen near as much as it used to.
Wow!
What a mess, you did good on the repair, if I were the owner, I would have replaced the heads. Be done with it. Good video
I agree, but the van may not have been worth all that.
Holy cow Kenny you had to get jiggy with a side of a Mcgiver.
I didn't see any shoe strings or gum
Yeah, you can save it. Your Kenney and your wrenching!
Don't blame: the customer, previous repairs or the shade trees that did them, blame FORD
Damn, this is painful to watch. I've actually installed one insert before, as correctly as I knew of at the time, and I never had any problems with it. I was *not* aware that you should use different flat bottom spark plugs with a gasket along with that sort of fix though, but it makes sense.
Still, I had absolutely no problems with my repair. It probably helps a lot that I took machine shop in high school though, but yeah I wasn't aware of the different spark plugs that should be used with that fix.
Thank you for sharing, today I learned a thing. 👍
He only needed the different plug to seat the sleeve.
@@oldschooldude8370 Oh? Okey dokey, gotcha. At least I didn't have any issues with my fix, my insert seated fine using the regular spark plug, and of course loctite and the flare punch tool.
I remember an apprentice using this tool on a Camero, insert went in and locked in fine. When he gave me the tool back I noticed a big chunk of the tap was missing. As you said about the 11:30 mark , valve was open , tap hit the valve breaking it and the valve. Had to take the head off
DRAG, aww man
Bravo, I love watching a master mechanic fix stuff right. What does a repair like that cost labor not including parts? Approximately? You do fine work.
If I ask the same question at ANY shop the tech shrugs his shoulders. That's the signal for the secretary to check my credit score. Anything below 800 and they keep up the "stupidity act" hoping you'll just leave.
Do I seem angry about car repairs?
If you'd went thru what I went thru to get a rear end swap. It was easier to just do it myself.
Kenny? How much to swap a rear end on a dodge 4x4?
GUESS.. Just take a wild guess
It still amazes me how many people are still out there that have no idea on how to work on vehicles
That is fine, as long as they don't work on them.
Am thinking the problem with a Helicoil not sealing is that there is a coil above the coil below when the tab is broken off. The spark plug shown uses a tapered seat to seal. Can’t make contact all the way around. A bit concerned about same with the steel collar thread repair shown. But less concerned. The setting tool may form the top to create a sufficient flared seat.
you're amazing.
I cut the cuss graskret off.
😂😂😂
For the original mechanic on this disaster:
ACHTUNG!!!
Das machine is nicht fur gefingerpoken und mittengrabben. Ist easy schnappen der springenwerk, blowenfusen und corkenpoppen mit spitzensparken. Ist nicht fur gewerken by das dummkopfen. Das rubbernecken sightseeren keepen hands in das pockets. Relaxen und vatch das blinkenlights!!!
Keep the good stuff coming Kenny.
The translation to English still didn't work 😢
this is not a translation, it's a joke.
@@johnnylightning1491 still didn't make sense when it was being translated to English
I strongly recommend using a thread chaser as opposed to a tap. You want to try to reform the threads, not recut them. Cutting new threads the same size, where does the excess metal come from? To recut threads makes a much weaker threaded hole.
A great way to demonstrate the installation of the insert. You can easily see what could go wrong inside the engine.
The only thing I will add is make sure you have the correct tap. I am a pipefitter, pipe taps are tapered (NPT = National Pipe Taper) and going backwards like Kenny did here would wreck the threads. So like Kenny did, make sure you have the right tap and things will go smoothly.
Please add a link to part 2 of your videos
Thanks
Had that happen to my Snap On spark plug socket causing me to leave plugs loose in an LS Tahoe so I ground my socket down so that sheet doesn't happen again.
Good save. Now get yourself a proper tap handle, and for god's sake use cutting oil when you are tapping or even chasing old threads. Could have very easily used a screw extractor to pull that insert out from the opposite side. Super easy and about 10 fewer steps.
Anti seize too folks!
