03 expedition broken spark plug

Hi there everyone. I have a 2003 5.4l v8 triton 2 valve expedition. Recently got it from my father in law and i dont think he ever had it serviced. Changing out the number 4 plug rear passenger side the spark plug broke between the nut and the thread. There was alot of rust in the housing.

Wondering what tool i can use to get it out. Ive been soaking it with kano kroil and will try using a screw extractor to get it out.

Today I started her up and now there is a loud ticking noise coming from the area of the broken plug. I stuck my finger down in the hole and the noise became muffled also i could feel air blowing out. Ticking gets slower in idle and faster if revved.

Any ideas or tips would be amazing. I really dont want yo pay 2 grand for shop to pull the head. Thanks!

I saw that tool but it says or 04 and newer and 3 valve only. Would it work on a 2 valve? They use different spark plugs.

After more research and talking to some friends i think/hope the ticking sound is being caused by the broken plug coming loose due to the kroil. Can anyone confirm this diagnosis?

The ticking noise is due to a hole in the center of the spark plug where the center electrode was.

Wouldn't the noise have been there the whole time? I drove it a few times after the initial break and there was no tick. It didnt start until today. Broke last weekend. Thanks for the reply.

It could've simply taken a bit of time to blow it out and make the hole. Hard to say without being there to see it.

I can speak from experience that you are likely in for some work or $$. In any case, until it's fixed, I'd disconnect that injector.
