Broken Spark Plug

[Diana]

My spark plug broke in half while I was trying to remove it. The ceramic did not get stuck. Any suggestions on how to remove it?
Thanks.

Re: Broken Spark Plug

Are you saying the hex of the spark plug is still there or that it broke off between the hex and the threads?

Re: Broken Spark Plug

Yes, it broke off after the hex.

Re: Broken Spark Plug

I've never seen a plug break like that before. They are pretty beefy. Did the plug have a tapered seat or a crush washer seal? Any evidence of rust on the plug? Can you post a picture of what you pulled out?

Did the electrode and ceramic all come out with the hex plug? If there was no chance that anything other than the threaded portion of the plug is left in, I would get a) some PB blaster, b) an appropriate size eazy out c) a propane torch.

Apply PB blaster and let sit overnite, then heat around the plug hole with the torch, then apply the eazy out.

I've run into that problem on 3 seperate engines in the past couple of years. Funny thing, they have all been very rusty Champion plugs.
All 3 plugs came out with an easy out easly as Boomyal mentioned. I used Aerocroil penatrating oil and an oxy act. torch, but the results were the same.
The only thing you really need to watch for is the bent electrode on the end of the plug. It's always just straightened out when the easyout was put in. Just make sure it doesn't fall into the engine. Or you WILL have to pull the head to get it out.

I have never used champion plugs but I always use anti-sieze compound when I install plugs and lugnuts.

Re: Broken Spark Plug

Ya want the easy way or hard expensive way? If you can't get a clear shot at it, remove the manifold so you can get at it. Being it broke after the hex, the center should be out. Find a easy out that fits but don't put it in yet. Take a torch and heat what's left of the plug till its red. Shouldn't take much since its thin metal. Tap the easy out in and screw it out. I do dozens a year that way.

Let's work on using this forum. NEVER use the

Just scroll down to the bottom of the thread and use the Instant Reply box. Type in what you want and and click add reply.
If you want to post a picture, forget the "Attachment" link in the MORE link. Nothing there works.
To post a picture, just make sure your picture is on the web and use the URL of the pic and click the

Re: Broken Spark Plug

Wow! That thing is corroded to heck! Is it a marine plug or an auto plug? Marine plugs are more corrosion resistant.

Re: Broken Spark Plug

You need to get the rest of the porcelain out. I would see if cranking the motor (with the coil wire disconnected from the distributer cap and grounded) and see if it will blow out. If not, then I would start the engine up (maybe even rev it some) hoping that may work.

Re: Broken Spark Plug

Looks like those plugs have been in there forever.
Whatever you do don't put Champions back in it.Put a dab of anti-sieze on the threads..Good luck!!

Re: Broken Spark Plug

Be sure to use PB Blaster on all the others before you try to pull them.
