Broken spark plug
Hi
I am new to this forum. A year ago I bought a 2000 F-250 with the 5.4L 2 valve motor. I was changing my plugs yesterday. The number 7 plug broke off. The shell of the plug is in the head still. The porcelain part came out. I tried to use a square easy out but the shell won’t move. Can I drill it out and retap it or do I need to pull my head? What is your guys suggestions on this.
Thank you

You need this special tool kit from Lisle. It works great. You can get it online, but Matco Tool dealers have it too. Also, you'll need access to compressed air and a long wand air-nozzle. If you're anywhere near CT, you're welcome to borrow my Lisle spark-plug tool kit.

I would think the only bet is calling a machine shop , having them drill and tap it, then helicoil it.

Have you been using an impact to remove plugs, and putting a “dab” of never- seize on plug threads, then torquing them into place, for new ones.
I have never had trouble since I started using an impact, “use it gently”, I think the impacts shake the carbon loose from the one or two threads that actually go into combustion chamber. Just saying!!

I had no desire to work on a hot motor, so I had the dealer do it.

soak the area with Kroil for a day or three and see if you can wiggle it out by hand. If it where me I'd tap it down a bit before pulling up but, I've been down this road before and know the consequences of making stupid decisions.
Another option is to soak for a day with kroil, tap is very slightly down, then crank her up and see if the engine will push it out... Oh forgot to say, maybe put a blanket or something to stop it from customizing your hood.

The spiral ones DO bite harder. The biggest drawback is they also tend to break easier so you've got to make sure you're square to whatever you're removing.

Hi Guys
i wanted to give you an update on my truck. I got the broken shell out of the head. I got the new plug in . The truck is back on the road. Now I get to tackle the valve cover gaskets.
thanks
