Spark plug change from hell. Pic inside
i pulled mine last October. Did two bottles of Techron prior, soaked each plug with PB blaster, doing about a 1/4 turn, respray and soak on a warm engine. Still broke 5 out of 8. Ordered the Lisile tool which made all the difference. As I used the tool, Broke the electrode strap on all 5 of them.
While not a guarantee, its been my experience when you have foreign debris in the cylinder, IF its small enough, it will likely just get passed through the value and out the exhaust. So each time I pulled a plug, with all COPs disconnected, i would crank the motor to blow out the debris. Looked like a party favor going off there was so much crap. Then I would install the new plug and move on to the next one.
Maybe this was a poor idea, and I just got plain lucky. But 3mo later and 1500 miles roughly, truck is running better than ever. I didn't do the anti seize on there, but will definitely try the impact next time.

i also agree. changed mine again after close to 40,000 miles and they came out like butter no squealing.
Just a friendly fyi, my best friend works at the ford dealership doing jobs like these every day, he told me all they do is let the engine get up to operating temp idling, then pull it in, shut it off and immediately soak the plugs in tranny fluid(or until it stops boiling off if such happens, then they let it sit over night. The next day they hit it agai. With tranny fluid and wait a few hours. After that he said they pop right out. That's what ford emailed them as a quick solution when this problem came about.

No wicking will occur, and any deposits binding the plug to the bore will not be softened ( other than whatever the heat will do ).
Why do you think that every procedure published that specifies using a liquid solvent also involves crackin' the plug seat a coon-hahr?
He either missed telling you a few steps, or it's BS.
