living with ford spark plug blow out problem

Well I did not know to look when I changed the plugs. Wish I knew what I know now.
My curiosity may get me to pull a plug and take a look.
My right front, nbr one, was a piece of cake. If I think I can get an eyeball down there I'll take a look.
or maybe just let sleeping dogs lie.

That's interesting but the reach of a 4 thread vs a 8 thread plug is big. I would think these heads were designed for a specific plug? Different heads, different plugs. With that long plug the plug might be in the chamber, the short one not. Am I missing something?
28 ft lbs is the way to install 'em

4.2 is not considered a modular and the plugs dont blow out of it. There are lots of aluminum heads out there that the plugs dont blow out.. There are several reasons it happens. Loose coils damaged/cross threaded plugs under torqued.. Many members on the bord have hundreds of thousands of miles with out blow outs. Theres generally a reason it happens.
I had to helicoil one of the plugs on my 03 4.2 today. It only took about 30 minutes or so. $40 for the kit at Oreilleys. I always expected my 1997 4.6 F150 to blow a plug, but she never did in the 5 years that I owned her.

Any head that has a plug work loose can blow out. GENERALLY the 4.2 does not loose them. GLC is right that plugs most likely gonna blow again. Timesert or Fords lock-n-stitch. Those are the only repairs that last.

Just got me
the dreadful sparkplug blowout caught me by surprise, as I started my truck to leave the gas station I heard a loud popping noise. I checked under the hood and my coil was bouncing everywhere. I was not aware of the blowout problem but was aware of several other triton errors as I've owned my 2001 f150 for the past 6 years I've spent more time under the hood than I ever had with any other vehicle. With my truck pushing 240k I researched several sites and was surprised at all the others that's had this happen. I went with the dorman cylinder repair kit. I was fortunate that my coil didn't need replacing. It seems like every month there's always something happining to the triton v8 5.4. I'm no mechanic but with the 5.4 I know it like the back of my hand. I'm just curious as to how it would run with that one injector unplugged.

I didn't have any time to research this because I was in a time pinch to get the pickup back on the road and running on full power. After I did some reading I had found a lot of bad helicoil reviews, and if I have to do it over I will buy the Timesert kit. Hopefully this holds up against the odds. 😁

Dorman insert
I recently installed the dorman insert with the long sparkplug, just wanting to know if this plug is harder to blow due to its size and if this plug needs to be torqued to 28lbs as well I also noticed that the coil pack doesent go down as far as the other ones with this plug is this a problem?
