Seize Spark Plug

[XcluziveAZN]

I'm doing lower seal and upper seal tube thing change

I'm try to remove the plug

So Far i got 2 and 4 out

but 1 and 3 is Seize....I don't want to put all my force on it.


I let it soak with WD40 for 15 and still noting

What should i do? Get my little cordless impact? or Let it soak or Leave it alone LOL

hmmmmmmm if u use a impact b really sensitive on the trigger

[honda_kid]

dont use an impact on park plugs. thats not a good idea. let them soak a little longer and try again. you can tug on a 3/8 ratchet kinda hard but i wouldnt put a big breaker bar on it or anything.

A little trick I learned when you let a motor sit is to use ATF in the cylinders so the motor its self wont seize up. But if WD40 dosent work then trial and error. Was it sitting outside in the rain? Over torqued? You have to be careful with aluminum. Torque wrenches are your best friend and money and time saver. You dont want to have to Helicoil.

You really can't helicoil a spark plug hole anyway... You'd need something more durable, like a timesert.


Try restarting the engine as it is now (all plugs in...) Let it warm up, turn it off, and let it sit for a while. Let it cool off. The heat cycle might cause the plugs to loosen. DO NOT touch them while the engine is still warm, or you can do damage. Things expand with heat.

With bolts, you can sometimes break a stuck bolt loose by tightening it a tiny bit before you try to loosen it. That MAY work, but the aluminum threads of your head are very delicate... so if you try this, do so at your own risk.

you can helicoil a spark plug hole. its a common problem on ford 5.4L's and they have aluminum heads.
i wouldnt try takin the plugs out when the engine is all the way up at operating temp, just let it cool for a little bit then try to take the plug out.

I have damaged threads in 2 of my cylinders... I did extensive research, and I've heard nothing but bad things about Helicoil on spark plug threads. They aren't strong enough, and they shift. Timeserts are MUCH sturdier. They are extremely popular with that same Ford crowd (my friend Jay, a Mustang guy and Ford mechanic, 92accordDX on here, is the one that told me about Timeserts)

[9DUBWISE]

Timeserts eh? Will check that out. I do agree with you about the dependability of helicoils. Hate em

[bcjammerx]

never heard of timeserts...but I'm about to change that

[jumpncrash]

I had a stuck one for a while, I just liberally sprayed 3 in 1 penetrating opil in there, tehn ran the car
then more oil, then ran it.
It eventually came apart.

My uncle got it off.

First i tested on crashed integra. It was seize....My uncle got in there and took it off.

What he did was 3/8 and Copper Pipe!


I did not have balls to use all the man power in spark plug. I was always afraid of the thread breaking inside.

Then He took a seize one i have in my CB

and Then He took 2 off in my friend civic.

Man 3/8 and Copper Pipe Works wonder.

[deevergote]

"Seized" is the proper word.

And it's your friend's Civic, unless that particular Civic happens to be your friend.

And do you mean copper pipe? Or is Cooper a brand of pipe that magically removes spark plugs?

[XcluziveAZN]

:Fail:

Thank you for the correction. I will take note of that. I really need to work on my grammar

[bcjammerx]

Y'all heard of Calvan inserts? Supposed to be better than timeserts...haven't looked into them myself.

Looking up timeserts and found this site:

Wd-40 is next to worthless to loosen up stuck bolts. It was designed primarily to drive away water and protect the Apollo space project from rust, not as a rust penetrant.

Get a can of PB Blast, which is designed to break away corrosion and free parts. then do the same thing with PB blast and be patient.

Next time you put your plugs in, make sure you put anti-seize compound on the threads. They seize because the plug threads are steel and the head is aluminum and there is an electric charge between the two metals, encouraging corrosion which results in bonding.

Good luck.
