Best thread spark plug repair kits according to redditors

You need a kit like this.

amazon.com/dp/B0002SRF4O

Its a simple repair.

It's actually a Time-Sert threaded insert to repair it. They drill out the spark plug hole, re-tap it to the insert size and install the new insert. Don't even have to pull the cylinder head.

You can see the tool kit here on amazon, the actual inserts are around $12 each.

The plug hole should be repairable. They make spark plug specific heli-coil kits, with a reamer / tap that will cut a new thread for the heli-coil insert to fit into, then screw the heli-coil in and lock it in place, then put the plug into the heli-coil. Here's a link from Amazon for the kit. This kit is like what you want, but it's not the right thread, I'm still looking for the right one, which is an M10 thread.

Try Aero Kroil instead of PB Blaster, or try a 50/50 mixture of acetone and transmission fluid. A long, six-point box end wrench will work well to unscrew the sensor. Then use one of these to clean up the threads in the HO2S bung.

Yup. They sell helicoil kits specifically designed for it

Example

You buy a kit similar to this (its based on the thread size and pitch of the plug) https://www.amazon.com/Helicoil-5334-14-Thread-Thread-Repair/dp/B0002SRF4O It is a steel insert and not a helicoil.

Or you take the head off and replace it or repair it.

Happened to me about 2 years ago. This was how Boosted responded when I asked if it was something I could fix myself. Still works great since then.

"sorry about the striped motor mounts. We have that happen occasionally here and that can be fixed with a 8-32 helicoil kit and a tap handle. I found an example of each to reference on amazon.

It takes a cr8EH9 plug. With a 10x1.0 thread size.

thread insert

Check to see if this vehicle has had Heli-coils or Timeserts installed due to plug blowout. Heli-coils are a good stop-gap fix to get you moving again. Timeserts are a more expensive, but more permanent solution. If it has never had a plug blow-out I'd highly recommend investing in one of these kits and keep a tube of grease and red thread-locker in your vehicle. Even if you lose a plug you'll be able to be on your way again in about an hour once the engine cools (30 minutes to install the insert, 30 to give the loctite a chance to set). The only other tools you'll need are a ratchet set with 6" extension, spark plug socket, and hammer.

Amazon a little more affordable. www.amazon.com/dp/B001SOHXLQ/ref=cm_sw_r_cp_tai_wfPDDbEG7FVRR

Thanks, never knew about this tool before.

This is what you need


When done you can use a standard 10-32 screw.

the kit comes with an installation tool and instructions.

I would probably hit it hard with PB Blaster and/or ATF fluid and let them soak in overnight, then following day try the removal. Maybe an Impact gun on lowest setting (and also lower the air pressure to half as well to ensure not too much torque on them)

I have heard of people using a helicoil tap kit to redo the threads entirely. (This may not be the right size for you but concept: https://www.amazon.ca/Helicoil-5334-14-Thread-Thread-Repair/dp/B0002SRF4O)

When I was looking into a P71, there was lots of talk on the Net indicating that this can be a problem in both the 4.6L and 5.4. An earlier issue seemed to be the opposite of plugs getting ejected while running and taking the threads with them...

I would probably use a tiny bit of never-seize on the damn things when they get replaced, but just about everyone out there disagrees with me on that.

Having said all of above, all my current cars are iron heads, so I am not at all expert on Aluminum ones

I'm assuming you have the 1.9l engine? We install the repair inserts on those where I work for $100. It takes the same insert the 5.4l triton engines do that always blow out spark plugs. They are easy to do so i'm sure if you call around to local shops you can find a place willing to do it. Dephaze is right you should check the other plugs to make sure they are tight. I would probably just replace them all while you are at it.

If you want to try it yourself this is a simpler version of the kit I use. It locks the insert in very well. I have yet to have one come back. You can either pack the flutes of the tap with grease to keep the aluminum shavings from going into the cylinder or you can just fire up the engine for a few seconds after you tap the hole to blow the shavings out.

I would suggest diagnosing it, there are a lot of things that could be wrong. First I would check for spark and injector pulse, and I would jump out the codes like in that link I gave, to be certain that the 51 code is a powertrain code and not an ABS code. Because if you do have a 51, you probably need an ECM.

Between the ICM and the ECM, The ICM is the much more common failure point. It is where your 3 ignition coils sit. It's the more common failure point, but it is also often misdiagnosed when the culprit is a bad crank sensor as another poster suggested.

Start with testing spark and injector pulse. If you don't know how you need a Spark Tester and a Noid Light.

Side note, I much prefer this sort of spark tester because it has more utility, being able to measure actual kV can be very handy on some cars, but the cheaper one will work fine for you. If you are going to work on your own vehicles, a Spark Tester and a Noid Light are both must haves.

If you don't want to spend 170$, here's an alternative I've used in my Civic https://www.amazon.com/Helicoil-5334-14-Thread-Thread-Repair/dp/B0002SRF4O

> This works just as well as a timsert and doesnt cost 2 arms and a leg https://www.amazon.com/Helicoil-5334-14-Thread-Thread-Repair/dp/B0002SRF4O

What is meant in the description by

This are woodworking project kit ?

Spark plug thread chaser

https://www.amazon.com/Lisle-20200-Thread-Chaser/dp/B0009OMYCO/

It wasn't a helicoil it was a double sides threaded insert thing. the tool we borrowed was something very similar to this

http://www.amazon.com/gp/aw/d/B0038B325I/ref=aw_d_img_back_automotive

Except ours had a pin you inserted and broke off, and it was made abundantly clear the aluminum in the threads were the same material as the head.


And the cylinder I'm having issues with us on the same head, but its the front most not the rearmost. Should I still be checking for ground?

Time sert kit is $90. Only 10% of total bike purchase price ffs lol

This $250 kit? Im looking for something more to the tune of $40.

Is this the Calvan kit?

If you get 2 to 3 full turns (360 degrees * 2 to 3) before you hit resistance, you probably didn't crossthread them, you probably hit some crud in the threads.

http://amzn.com/B0009OMYCO is a handy tool to clean up the spark plug threads before you thread the plug in, but you have to be very careful not to cross thread that tool. Also, have the end covered in grease when you use it, to capture all the crud that you get out of the threads. The best way to use it is to turn it backwards (lefty loosey) until it clicks straight, then start turning it in. That works for both the spark plugs and the thread chaser.

I used this kit to fix a stripped spark plug hole on an old trimmer. No real problems except the coil coming out with the plug the first time I removed it.

I've done 2 plugs now with the following kit. It's easy to do, and never had any issues with them since. Take your time, follow directions, and don't rush it. They hold solid and I've never had another issue:
