Now that's a theory I've never heard before. Can you explain to the class how carbon buildup would cause the threads to fail?

While I don't believe that the decrease in combustion chamber volume and the increase in net compression ratio would "cause" a plug to blow out - it is known that combustion chamber deposits can cause detonation / pre-ignition and the resulting pressure increases are known to be extreme and could contribute to the failure of the threads..

Welcome to FTE, Todd. I have seen a lot of opinions, both from Ford and from reputable certified mechanics, on how to pull a spark plug from the 2V and 3V 4.6, 5.4 and 6.8L Modular engines. It seems that all they can agree on is that these engines present a challenge.
