Broken spark plug in Ford 2v mod motor

[Julio6306#]

Good morning, in need of advice. I have a97 ford expedition with a broken spark plug ( broke at the base with metal threads in head) with a broken extractor in the plug as well that does not come out. They sell a tool Lisle which works on 3 valve not the 2 valve model. I am trying what I can to not remove the head since this would be a costly repair. Any thoughts or suggestions would be greatly appreciated. Thank you

What is the broken extractor? A Difficult-Out?

A picture would really help.

If there’s a broken easy out in it you may be pulling the head.

Gotta love it when some folks say changing spark plugs is easy to do.

Is the round object in the centre the broken extractor?

Step 1 - get the extractor out of there. But I don’t see how you can do much more than drive your “tools” shown above onto it. Drilling has about a 0% chance of working in that deep of a hole with a hardened steel extractor, and you have about a 99% chance of damaging the head.

But even if you get that out, you still have a stuck plug, and it only has three threads.

Safest course of action - pull the head and take it to a machine shop. Let them weld a nut on it and carefully remove it. If they damage the threads, and they might, even with care, they can install one of those kits to repair the threads.
