Spark plug help

[Chip18]

WOW that is "seriously" messed up!! As close as I came to that ... would have been had I chosen to work on my neighbors 5.4. I did some research and saw "broken Spark Plug Extractors" coming up a lot??? Apparently with those motors "Broken Spark Plugs" is expected??? I declined doing the job.

Some combination of post 6 and 8 would be a very good idea. Pull the head and take to a machine shop and say ... fix it.

But ... before going that route ... you could take that photo and try shopping around for a Mechanic that can get that part out without pulling the head??? Hey .... maybe a "Ford" guy???

I agree that you need to pull the heads, unfortunately. And dont forget to use anti-sieze when installing plugs in the future to keep this from happening again.

Use a small amount of anti-seize-- if it gets on the electrode when heat causes the grease to run down the threads, no spark

This sprang back to life. Lol. Also I would seriously use a HelicoIL as last resort. Alot of times a thread repair tap will work. This is not the same as a regular tap. And it's not the same as a thread chaser.

A thread repair tap has blunt flutes that are made to roll the damaged threads back into proper places and clean them out. Where as a regulart tap would just cut the damaged thread out and make a much weaker outcome in aluminum

Sorry for this super late update. I ended up having to put the project on hold for a little bit. But yesterday I was able to finally get 1/2 out. I used a #5 screw extractor attached to a 3/8 extension which then was forced into 12mm socket. After I got it to sit it came out so easy with some pb blaster.

But for the other spark plug that just spins I'm clueless on how to get it out. Thinking of running the engine for a bit then trying that.

Ok, now I'm afraid to touch my plug on my new-to-me '02. I have no idea when they were last changed.

The plug just spins? That would be bad. And I also see the ceramic is gone out of that plug you pulled. Did it fall into the cylinder? Even 1 small fragment of that ceramic will ruin your engine if you run it in the cylinder. I have seen it.

 

[brh11]

Yes it does so I'm thinking of doing the same thing and breaking it off like the other one. Also for the ceramic, nope I started the engine up, made a loud noise but the ceramic ended up blowing out of the spark plug perfectly. Also to be sure after I removed the spark plug. I ran the engine to make sure the cylinder was clean. Going to do it again when I get the other one replaced. Also for spark plugs 4 6 and 8 that are stuck. Apparently heating the engine up will solve it as the head is aluminum like the spark plug. I've used tons of pb blaster but there still a ***** to turn at all. So probably going to do that. Seeing as if I try to yank on it. Might be back to stage 1 again...

Kroil or crc freeze off will work awesome on spark plug threads du to metal difference

Ok. Maybe I'm wrong but, spark plugs aren't aluminum. and if it is spinning and not coming out then yiu have stripped threads and since the spark plug has stronger threads than your aluminum head, I would say the heads threads are gone. it's time to hit the junkyard or a really good machine shop. I hope for your sake that I am wrong.
