99 5.4 Liter F250, launched plug out of block and took out coil pack, not stripped or loose, is this a common problem, how do we prevent and or fix?

My 99 F250 SD v-10 did that quite a few years ago. Ceramic heads. Ford knew there was a problem but never issued a TSB. My local dealer covered part of the repairs. I had to put in a new head.

I have a 2004 fordf150 with the 4.6 engine. It has 58, 000 miles on it i take very good care of it. I was driving down the road at a steady 50mph when the #2 spark plug blew out i called ford and they basicaly told me these things happen bull it happens all the time. After doing a little research this is a big problem with the 5.4 and 4.6 ford should step up and fix the problem oh wait they did NOT now they are getting stuck in the heads after changing the design wtf. I was futher insulted when i went to the dealer to get a new plug he look at me as if i was talking about an older model and said i havnt seen this in the new body styles i gave him my vin# and with a academy like perfomance he was suprised. Ford told me it woul be between 600 to 800 dollars to fix i was futher outraged when i asked them if they could pick up my truck they were willing to give me a # for a tow company at my own expense are u kidding me. I bought a coil for 40 dollars a new plug for 6.50 and had a mechanic tap it for 50.00 dollars i came out pretty good now crossing my fingers this dosent happen again very disapointed with ford considering about dumping the truck.

My brother in law has the 2004 ford f 150. He had his spark plug blow out of his truck for the third time. They now say he needs a new head for 2500.00

I have 2001 F250 with V10, I have had this happen to me three times. #3, #7, #8 cylinder. I was very upset first time. I talked to the dealership and they said with the aluminium head I probably changed plugs while engine was warm or over-tightened. I've done all my own work fro years and never had this much problem. I went to local Auto zone and brought Heli-coil kit and put in helicoil each time without pulling block apart. It has worked out for me so far, the only thing I've done was ran the truck for a few minutes and immediately change oil.

I have a 2001 F250 V10 and I am on my second time having a plug blow out of the head. The first time it happened I had the head pulled new threads welded in and before I could even get it firing on all cylinders again, it has blown another one out!

I just thought that it was cause I have 219, 000 miles but now I see this forum I see that there's more to it.

I have been told to just put a new engine in it. Any advice?
