5.4L Spark Plugs Seizing Problems
#66
I just took my 2005 5.4L Expedition in for a tune up yesterday, I have 98k miles on it, found out about this plug issue and did some research. $780 later I have 7 new plugs. One was seized so bad (#4) they didnt want to go forward for fear of breaking it and said they would then have to pull the head........
Also worth point out that they charged me $150 for a fuel system clean that would clean alot of the carbon off and help release the plugs.
Does that sound right? So what am I supposed to do to remove that #4 plug?

Depending on where you took your truck and the skill of the mechanic, they might be able to remove the plug without breaking it. I know my local Ford dealer/service department has had good luck where other mechanics had not.
There is a tool for broken spark plugs and they don't require the head to be removed.
IMO - If you can't do the work yourself, go to the local Ford dealer and pay them to replace the one left.

I just changed my plugs on a 05 F150 5.4L ..
I used a technique I found on youtube.. Run the engine until its hot ( running temp) and then I used a 1/2 impact wrench on low setting and removed the front 6 plugs with no issues. ( I had also ran 2 tanks with injector cleaner prior to).
but, both back plugs broke. passenger side back snapped right at the base of the collar, I used my Lisle extractor on it, piece o cake, came out with no issues..
the drivers side back plug had the collar completely separate from the plug leaving the whole plug still in the head, minus the threaded collar.
I cleaned the plug, plug well and collar with brake cleaner to remove all the oil/grease I could.
Then mixed up a pea size drop of JB Weld and applied a thin coating to the inside of the collar and CAREFULLY re-attached the collar back over the plus insulator, tightened and let it cure for a whole day.
Needless to say, it worked Perfectly! I was able to extract the entire plug insulator with no breakage, then a simple extraction of the remaining metal tip from the head and install the new plug. ( I am using E3 e3.70 plugs, they are 1 piece metal bodies).
I hope this may come in handy for anyone
