Man, what a nightmare. Another of the many reasons why I don't like taking my vehicles to a repair shop. Mechanics now a days just don't take care of your vehicle and could care less if they screw up a job and not inform you about it. Worst part, they never assume responsibility and make up stories to get off the hook. This is why I learn to repair my own vehicles. Thank you Mr. Toyota Maintenance!! Your videos are always informative and the best videos I've seen so far. I can tell your a one of a kind honest and humble mechanic!!

Right

[@gofgwoodworking]

Just repaired my 2000 Toyota tundra, followed your direction and it went perfectly. I had the advantage of a bore camera so after I cleaned out the cylinder to make sure it was perfectly clean. This is the most comprehensive video I have found, thank you.

[@dping43]

Just subscribed. This video saved my ass! Big time! Had the exact same issue with #8 and followed your step-by-step instructions and worked like a charm! THANK YOU!! Can’t imagine how much money I saved by doing this myself.

[@ignitingfaith2044]

Worked perfectly on my 2006 Toyota Sequoia!!! Did the complete repair for about $70. Thank you for this great video.

[@TomWoodwardLooksmarvlus]

Great video. I'm just turning 70 and had my first plug blowout this morning on my 2006 MINI R50. After watching this and seeing the MINI in the background I am confident to give this a shot!

[@CapCityDC]

Of all the KZbin videos on how to do this repair, this by far is the best one. It shows the best way for how to clean out the metal shavings. Thanks!

[@user-cw7pm4vc1x]

Don't use this kit. Get a Timesert kit. It locks the insert in the hole. Thread-saver can pop out.

[@elnidoelnido]

I had a grey 2004 tundra dc. I sold it with 193k (all possible maintenance including 2nd timing belt and water pump.). This video brought me back some great memories! I got a 2014 which is great... but that 2004 was special.

[@alanc7827]

Thanks to this video, I was able to complete the the same repair in my 2006 Acura TL. Thank you so much -You're awesome! I also did NOT want to hit the Helicoil with a hammer, so I purchased the Permatex Red.

[@RJ.................]

I'm thinking about doing this to my 07 tl

[@davec.1045]

Just had my 01 4Runner throw a plug and destroyed the coil. Threads stripped. My mechanic is going to do this repair for me on Friday. I love your videos. Keep up the great work!!

[@1ronhall]

I was pulling for you friend, but I knew early on you were going to have success because of your conscientious mechanical approach to the job. It is reassuring to watch you methodically undertake these Toyota repairs. Thanks, and continued success!

You say it well

[@harmdegraaf5579]

Thank you for posting this surgery. A job well done and very educational. Thanks 👏👍

[@jamesmahle1259]

Love your honesty and approach to mechanical adventures.

[@biffcabhash2428]

Can’t say thanks enough for this - followed this to a tee and right after degreasing with brakleen i below it out with the air nozzle and started the car up with no plug in #5…blew everything out. Worked like a charm - i would say you could also use duct tape built up around your socket extension shaft as a centering device - along with some Saran Wrap in the “wiggly” part inserted into the extension and tap to tighten it up a bit…GREAT JOB!!!

[@obc1500]

I’ve had to go through that Pete lol 😂 I prayed and it was answered good video

[@wattage]

This was a really good video to watch. Learned so much! I could tell you were genuinely nervous before starting it. It's encouraging for me to see that, sometimes, even the dedicated professionals have doubts and hesitations. But your slow and careful approach paid dividends. Another bulletproof Toyota back on the road! Looking forward to all the upcoming videos.

[@azizlenox]

Great job. Please keep us updated every 10K miles :)

[@ToyotaMaintenance]

I will

[@PerculesMr]

@@ToyotaMaintenance How did the insert hold up? did you try removing spark plug afterwards? If so, was the insert/thread damaged by any way or form?

[@BenG123]

Awesome video! Congratulations man! Have fun camping with it!

[@ToyotaMaintenance]

thank you

[@weekendwarrior3420]

Nice concise video, almost perfect.

[@BENNYBLANCOFTB]

Awesome Job,My Friend Bravo.👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

[@georgesanchez9971]

Good video. Thanks for making it. I think is a very good idea to wack the top of the plug with the provided pool. I will also wait for the 24 hour cure. Red locktite sometimes can be a little difficult to obtain good result if it does not cure for 24 hours.

[@showgirlsaroundtheworldada4484]

Helicoil is great! I had a head done years ago on my fiat 850 sport coupe racer...aluminum head....

[@on-site4094]

That’s a great installation procedure when they recommend hitting the the insert to spread the top i cringed,,, 😬 and the torquing procedure its great to see a professional mechanic 👨‍🔧 at work with a conscious 👍thanks for sharing

[@robsummers8210]

it okay to hit the insert I think. It was a trick they told us in Machining school, as a quick fix when threads are loose and a little out of spec - kind of a cheat ;-)....lol

[@Jonodrew1286]

Great job: I used to use helicoils - but they are tedious with the tang and thread skipping - I only have one issue with your setup - sometimes using solid lockable inserts - the insert can come out with the new plug as the clamping pressure bites onto the insert and is able to grip it sufficiently to lock against it so when changing them the insert can sometimes come out too!! Good work though 👍👍👍

[@slam44]

Excellent tutorial!

[@idahodeerhunter]

Good job! I was rooting for you!

[@ToyotaMaintenance]

thank you

[@showgirlsaroundtheworldada4484]

I didn't know it could be done with head on car....amazing

[@davidpantaleon2166]

Amazingly done your the best watch the whole video tit the end good work my friend

[@ToyotaMaintenance]

thank you

[@rawfoodphilosophy7061]

Great job on putting the Loctite red gel on there I was about ready to go nuts in the comment section but that should make the coil never ever ever ever come out and you should be able to easily remove that spark plug the only thing is if possibly some of that let Loctite would spill over so some people put it in without the spark plug and then they try to remove the lock tight that has spilled over but you put such a nice small film on there that it should work out just perfectly but great job man thanks for doing the video appreciate it

[@youfrancis]

It's like watch a doctor perform surgery. Beautiful work.

[@MixmasterChode]

Thank you!! you mentioned a few tips that dozen of other videos don't... Great job!!

[@ToyotaMaintenance]

thank you

[@pup734]

Another job well done thanks for sharing

[@don7406]

I had no doubt your helicoil would hold. When properly installed it should be as strong as the original. Nice work capturing the aluminum shavings.

[@ericgoins9125]

Right

[@TheFlexTapes]

Love this, great detail thankyou

[@fierymario3]

Good content man keep it up. I have a 2003 4Runner and Would love to see repair videos of it. You should buy a 4Runner and have a fleet of Toyota trucks in your garage.

[@b_hill1380]

Did you set the helicoil in with the hammer. I’m sure it dosnt matter if holds or not, just threading out if you have to remove the plug.

[@Velcrostraps91]

Okay I have 99' 4 runner. Same problem. I've watched this video 6x and spoke with others on the matter for opinions. I'm no tech but with this great help I think I'll tackle it. Wish we had a local guy like you. You are tremendously appreciated.

[@musicman6311]

how did it go ? did u finally do it ? i m about to try but not sure how far should i screw the spark plug in?

[@rameshpersaud7131]

Great job thank you

[@BlackLung911]

We owned a Renault Traffic 1.7 OHC with no3 spark plug thread needing a helicoil. By the time it was done the engine had burnt the piston in half needing a new piston plus head job. BTW these Renault vans along with Vauxhall & Nissan counterparts from 1980's onwards love to throw the input shaft of the gearbox for no apparent reason.

[@eddsmith4922]

Maybe I missed it but did you remove the spark plug and set the insert into place and how hard was that?

[@vicorgomez1590]

Awsome video👍👍

[@swissmonkey3767]

Thank you so much!!!

[@stevanrose7439]

When I first got my 2002 Tacoma it had a bad plug in number 5 and it came out like someone had put it in sideways. So I put some anti seize on the new one and it went in easy. Like nothing was wrong I changed the rest and haven’t had any trouble sence. Keeping my fingers crossed.

Thats how its done great job sir! I did this to my 2.0 mazda b2000 engine. I didnt see u take the plug out and hit the end of the heli coil though. Im sure u did it and u didnt show it.

[@ericagrey7828]

I didn't do it and had big problems

[@mikeisgonz0]

He didn't do it. He used red permanent threadlocker instead. I believe that the threaded insert will not back out....

[@michaeldunagan8268]

I enjoy your videos. I bought a 1986 Kawasaki 454 LTD. The bike ran great. The only thing it did was idle high and then idlewood increase as time went on. What I fix the vacuum leaks, I could no longer get the bike the run unless it was fully choked. What I pulled the spark plugs out, I was beside myself that whoever put them into knot torque them to specification the same as in your video and on my 1999 Toyota Solara V6. When I went to put the spark plugs back in after cleaning them, then the sky fell on me and I realized that the threads were stripped. I am just too paranoid to do this cuz as you said in the beginning of the video I don't know if I can stay square to the spark plug hole to make sure I drew a true 90° to the surface area. With a motorcycle, it's about $250 just to buy a new head. I am unable to get soft quotes over the phone from machine shops around me Chicago suburbs to do this work. But at the $150 an hour labor rates from shops around me, I'm sure this job would Bill 2 hours so I think I'm just going to be a head getting new cylinder heads. I don't think there is enoughl clearance to get a drill into the spark plug hole to drill by the heads are still on the

[@socalwoodworks3007]

Brilliant.

[@Tenright77]

Thanks TM.

[@ToyotaMaintenance]

you are welcome

[@hosocat1410]

Great video, as always. Im not sure i understand how you cleaned out the hole. Are you spraying brake cleaner down into the cylinder and then using compressed air to blow it all out? I have a tundra with 190k. No stripped plugs yet (fingers crossed). Thanks for sharing your expertise.

[@eurovan03]

How did you move it cylinder down so you can retread it without damaging the heads .thanks

[@kittyberto]

I enjoy your videos but I wish you can show the after fix/repair videos to know if your findings were correct .Thank you

Thanks man

[@craigmoon4641]

have a 75 Volkswagen I see someone had installed a helicoil in the #3 plug hole that's gone bad and wondering if I could just remove it and replace it without drilling and tapping it again? Thanks for any advice!

[@everready19373]

Good job man! You're very meticulous.

[@positiveenergy7885]

I think the insert is supposed to be inserted into the cylinder, and the tool that comes with it you pop it in and tap it with a hammer- which expands the bands. Then you thread your spark plug into the insert.

[@showgirlsaroundtheworldada4484]

Excellant!

[@user-cw7pm4vc1x]

Use a Timesert kit only. Get the extended kit. It locks the insert in the hole.

[@AJChen-xo1uz]

3:37 how did you turn the engine to open the piston? Do you need to pull off that black plastic vvti cover to expose the 22mm bolt? Thanks for the video!

[@izzy29413]

I changed the spark plugs on a GX470 and cleaned the throttle body mass air flow sensor, I did say a prayer, you never know 😂

[@showgirlsaroundtheworldada4484]

Toyota man what is the proper idle after warm up for my sequoia 11 or 9 or what do you suggest?..mine usually hits 9 after warm up

[@kylemoore8088]

Maybe another good idea to remove aluminum shavings.. use shop vacuum duck tape “flexible tubing” to end of vacuum that will reach into spark hole and inside to cylinder

[@bethclay3111]

Another way to remove shavings is blow it out with your air

[@TheSaxophonecat]

Thanks for the thorough and sometimes entertaining video. I am doing the same thing on a much older 4RUNNER . 1999 to be exact, did your Helicoil Job hold? I hope so… I am praying that mine does. In the middle of the pandemic with the economics that exist I don’t have much other choice like many other people. Ca va !

[@bakanibaleni5865]

Good video, well explained, i have a similar issue with my car it uses the same size of the spark plug with yours 14 mm. now i want to know what reamer size you used for cutting the threads?

[@magicone9327]

So you didn’t impact and swell the knurled top end to the head?

[@user-dr1bj1bq2e]

Nice video buddy so happy i seen it only thing i did different was use the green thread lock because its high tmp ✌ be blessed thk you and im guessing a oil change isnt a bad idea after this ? Or ...

[@-johan9841]

I did this same repair and used a much smaller amount of red threadlocker for the insert. I had to remove the spark plugs again for a different repair later on and found some of the cured threadlocker on the end of the spark plug. There was also some red/brown colored burn off on the walls of the spark plug hole. The engine is running for now but I'm not sure if threadlocker is the way to go here.

[@tarzan30809]

Not sure if it heat resistant

[@Velcrostraps91]

My only question. Please explain the turning of the piston? Or how you turned it? That's the only thing I'm not grasping.

[@legitimateballer1236]

Hello, will this kit work with spark plugs off a 5vz-fe?

[@waldenlee1914]

where can i buy the coil pls and what would be the size that matches the spark plug

[@drtydave9124]

What type and brand of grease do you use? I used liquid wrench when I did this before and still had alot of shavings to get out. I have to do it again on a different cylinder so looking for a cleaner way if possible. Great video by the way.

[@chocolate_squiggle]

If it's not too late, looks like he still had the tub open on top of his toolbox at 8:18 - some type of marine grease. If you're familiar with USA brands you might recognise the container. [ update - Lubrimatic ]
