Okay I was pulling the spark plugs out of my 2004 F150 and I broke three plugs off and had two of them pull the metal sleeve out and left the rest of the plug intact still in the head. I had the Lisle tool and got the three broken plugs out now I can't get the two that have the metal sleeve pulled out. Should I be able to just put a pry bar down there and pop them out or?
Thanks for the help

Not sure what you're up against... but I'm not thinking a pry bar is the best tool for the job.

I've not seen many plugs break in the manner you're describing... can you post a pic and show us what's came out and what's still in the hole?

If the metal sleeve you're referring to is the part with the thread on it, then I don't see how that would come out and leave the entire porcelain head intact in the cylinder, as it's tapered at the bottom (under the threads) and just wouldn't come out like that.

If you mean that the electrode pin remained in the hole, yes that happens sometimes... you can get a long pair of needle nose pliers (or needle nose vice grips) and pull the pin out, clearing the way for the Lisle tool pusher.

A picture would be most helpful.

No I meant the metal piece with the threads pulled out. I ended up breaking the porcelain and using the Lisle tool to get it out

 

Something here isn't making sense... I'm not sure if I'm being a blockhead or if you're not explaining it well, but I can't help until we're on the same page.

Let's do this... take a look at this picture of a broken plug (this is typically how they break):


So can you tell me, using the label #s in the pic, which parts are out and which parts are still in the cylinder for EACH cylinder... then we can figure out how to get you on the right path for each one.

Everything but number two was still in the cylinder. I ended up getting a pair of needle nose pliers and pulling #1 and #3. I then used the Lisle tool and pulled number 4 out. It's all done now but thank you.

 

Glad you're done!

I've personally never seen them come out like that before... the porcelain usually breaks between #2 and #4. Sometimes the pin stays in.

In your case, the technique for "Pin Stayed In" applied because basically there's nothing holding that pin in once the metal breaks.

Did you have to work at it with the pliers, or did it just come right out? (there's a little lip at the bottom of the electrode pin; usually gives no resistance, but curious whether it did with all the porcelain intact).

Thanks!

Changed all 7 spark plugs and numbers 8 is not coming out. Was corroded and so the nut was no good so I got the deep socket bolt nut remover and it just strips it off. The top is broke off so I tried an easy out and still just strips out as well. Porcelain and the pin is still in the spark plug.
Any help or ideas would be appreciated

 

I have found that using an impact gun will often break it loose because it's a series of short swift blows instead of a steady pressure.

 

Ok. Well let me see what happens
