Does anyone know if the sleeve around the sparkplug can be replaced? I was working on removing a broke sparkplug and damaged the sleeve accidently. It is punctured. So Am i stuck with getting a new head? any suggestions.

Thanks,

Scott,

 

The sleeve is part of the spark plug, not the head. Throw it away along with the rest of the broken plug.

 

Its not part of the sparkplug. its the metal sleeve that the spark plug goes into. it is deffinitley part of the head but it spins so I thought there might be a chance it is replaceable. its not the threaded piece of the sparkplug that comes off. hope that clarifies the issue a little better.

 

I know what it is. The OEM spark plugs are 2 piece, the sleeve is part of the SPARK PLUG.

If it's still in the head, it has to be extracted. Use a Lisle 65600 tool to get it out.

There's plenty of threads in the V-8 forum and the 2004-2008 forum about this issue, some with pics. Start searching.

 

What you see spinning is actually part of the spark plug that should have come out with the rest of it. Like GLC said, there's a tool for that

 

Hi Scott;

The plugs thread into the native aluminum head casting - there is no sleeve as part of the head assembly.

Here is the Lisle tool - refer to the cross-section pics, and the much more detailed info in the PDF instructions in it's use, linked on that page...

*EDIT* and here is another good perspective on the topic:

Last but not least - a very well-written article by one of our very own members - Jim Allen:

Good luck!

My sparkplugs are not sitting in a aluminum casting. there are 4 thin metal tubes for each head 1 per sparkplug. they are easily visible with the valve cover removed. I used the lisle tool and the tool sits inside this sleeve when you are extracting the sparkplug. maybe My head is not original, Im not the original owner so its possible. Anyway you drop the sparkplug into this sleeve and it screws into the threads on the head. when a sparkplug is removed *not broken* the sleeve spins freely but doesn't pull out. It is thin and I somehow managed to puncture it. my luck Im probably the first to have this happen. I will try and take a picture tomorrow and post it.

Scott,

 

With the valve cover removed???

The sparkplugs and the COP assemblies above them are external to the valve covers - they are not removed for a plug change.

This is odd - looking forward to these pics

Could you post a picture of the removed spark plug? It really sounds like the common broken plug shank deal..

 

This is a pic from the web. *Not mine* I changed 7 of 8 sparkplugs with no problem. this picture shows the channel or tube the sparkplug follows down to the head. I somehow managed to puncture it. It does spin freely thats why Im saying it isn't part of the head casting.

 

I removed the valve cover to assess any damages.

 

Well, I think you just stunned everyone This is a first, I think.

I'm not gonna ask how you punctured that. And I have no idea where you can source one, let alone how to remove it.

Do you have any engine builders locally?

None of the online parts catalogs I've just looked at show that part.

There are a couple engine gurus here that may be able to guide you.

Good luck.

It would be helpful if you would describe how you caused this damage so that others won't repeat it.

 

I have never seen that and have no clue what purpose it serves. Kind of looks like to me what your seeing is the ID of the intake manifold is slightly larger than the plug well so it looks like there is a sleeve there. That pic is from a website describing a broken plug, which you can see as well. Still not sure if that is an insert...

 

He did say it spun freely, I doubt that he made that up.
