Awhile back i posted about a tapping noise that my engine had been making. Well last week i was driving down the highway and one of my spark plugs blew out of the head. I read somewhere that this was a common problem witht he 4.6? anyways I am in the process of pulling the engine and I wanted to know what would cause the spark blug to blow out and could this be what was causing the tapping noise for the past 8k miles. Once i get the engine out ill get a closer look and and see what needs to be done, just wondering if any1 had some input before i begin. Im just glad i have a reason for pulling it so i can put some new mods on.

ps. now im stuck driving a hemi ram getting 10 mpg on $3.50 gas.

Hmmm, I've been wanting to do some major engine mods, heads, forged internals, new intake, bigger injectors, but the wife won't let me. Maybe if I blow out a plug, she'll let me do it!!!:eyepoppin I'm interested to see what caused this, too:winks !!

A lot of the cars will blow out plugs. It is common. It's because ford didn't thread the spark plug hole in the cylinder heads all the way. I believe they only threaded it four or five threads. I never had a problem with my car. But I know someone that had it happen to him three different times.

Wasn't there a silent recall for that problem?

Ford fix the problem by (i believe it was 01). Yes, the heads only had a few threads, which cause the sparkplug to be seated deepr in the combustion chamber, and Boom! If teh threads are stripped, you can put a helicoil in to repair. Do not over torque the spark plugs...no more than 11 ft/lbs (a bit beyond hand tight).

My buddy had an 02 GT and he kept blowing em out... Dunno why if it was fixed by then.
