2002 Ford Expedition blew out a sparkplug . Anyone EVER hear of this before?

I have heard of it with the modular v8

Plugs blow out all the time. I remember one day a cutie in a BMW came in to the station where I was working as a kid. She was late for a meeting and her car was making a terrible racket. I told her we didn't do mechanical work but I would look at it. I popped the hood and a plug had worked loose and blown out. It was still hanging by the plug wire so I got a wrench from my car re-installed it. Car ran fine, she zoomed off to her meeting. She did come back later than night and well shall we say, showed her appreciation.

Modular motors are well known for that it is because when ford made those heads they didnt make enough threads for the spark plugs so they have the habbit of shooting out

There is a recall on that take it to the dealer

Yeap- Last summer a friends 8 yr old motorhome with 460 cid- approx 60,000 miles on original motorcraft plugs blew one. Insulator stayed with wire-; base (threads only) remained in block.. 3 hrs labour, with easy out tool, to get rusted- in base out of block.... Neglect , severe rust.. To my mind, plugs should be pulled once a year and inspected, cleaned or replaced.

happened in my 88' firebird 5.0. blew the inside of the plug out but left the threads in the hole. left a dent in my inner fender well lol
