Attention Joe P or any one else on subject that can explain how this can happen. A administration member on another site claiming this happened on his engine while sitting at a stop light. Has anyone had this happen before?
Not sure what you mean about "exploding spark plug", so maybe this is different. I once had the ceramic blow out of a plug - the metal base below the hex rusted, the hex part came off, and then the ceramic insert was blown out by the cylinder pressure.

Well this guy claims that he found pieces of the plug throughout the top end of the engine. I just can't wrap my thoughts around that. If it blew out from not being torqued properly then I get it. That isn't exploding into the block and top end. He claimed idle running at stop light.
He also claimed it had been recently rebuilt.
There electrode and surrounding ceramic could fail due to overheating and end up in the cylinder, but the threaded part and above can only go the other way(out)
Ive seen both N2O, and Nitromethane( Top Fuel) cause plugs to melt the tips away.
I've known Thomas S for many years and he is also a member on this site. A liar he is not. I've seen exploding plugs that were destroyed due to detonation. I've had Champion plugs where the ceramic come apart and the centers blowing out, I won't use Champion anymore. I've also seen spark plugs that come in contact with the piston for one reason or another and have the ceramic blown out.

I agree that detonation can do damage but you would know that when it happened. Also coming into contact with piston will do damage but that's not the plugs fault. Now loosing the ceramic that could be what he is describing. But it sounded like a major failure of the engine to me not just a plug. But hey it's his story not mine. Thank for the reply Eric.
At the risk of getting into another argument with someone about structures...
Unless the insulator fractures, it isn't possible for it to go inward. Even if it does break, what sucks it in? I'm really struggling to come up with a credible failure mode here.

If the insulator fractured down at the tip, couldn't the intake stroke air movement draw particles down?

If the insulator fractured below the first seal, the pieces would fall in. There wouldn't be an explosion. It's 15 psi suction vs. 150 psi compression pressure pushing out.

Yeah, I don't know what to say about 'explosion'. That part is confusing and open to doubt if whether that truly is what happened.

What pieces were recovered, and exactly where were they found? Clearly the entire plug didn't go into the cylinder. The physically isn't possible. If some fragments of insulator were found there, where was the rest of it? I would assume it would have been hanging from the spark plug wire (though the one time I had an untorqued plug blow out while driving, it actually launched itself into the inner fender).

Exactly. More info is needed. We have just enough information to know nothing.
As said, I have had pretty good detonation in my 9.6 to 1 350 and never had a plug fail mechanically. It would have needed to be cracked all the way around the inner porcelain and the electrode separate and drop in. I have seen quiet a few motors with plugs seizing in aluminum heads. My friend had a plug eject in a 2.2 4 cylinder and the 5.4 ejected part and seized in the rest, due to the two piece design. Manufacturers usually design parts so if they fail, it isn't in a way that destroys a motor inside.
Ding Ding Winner to Joe Padavano on experience and explanation. Runner up Koda with ninth plug . Game over. As mentioned go to Sickfoose site see for yourself what he said. I am always amazed more than not Joe Padavano having great information. Thank you Sir for answering.
You have to join the site to read what was posted. Thats it, its a ploy to increase membership on a Facebook page.
I am not advocating that site. I am just telling what you what was said and where. Anyone who thinks I made this up go read it. You can un- join after reading it. LOL

I went over to that page and could not find the referenced discussion. What was the date?

Uh, you need a facebook account first, which a lot of folks don't have.
I read the post and talked to Thom. I actually remember when he had the issue with this car because it was just after I lost a cam lobe in my car when he was visiting a mutual friend in Glen Rose, Texas. He's in the military and was getting ready to get transferred to Vegas. I messaged him this evening and he said the engine sounded like a couple bolts in a coffee can and they think they had found parts of the sparkplug (probably the electrode) in the cylinder. Exploded, maybe not and probably a poor choice of words on his part as it happened about 10 years ago. The car has been in storage since.
Neely, why do get so worked up over trivial matters?

It also begs the question, did the plug come apart, or did some other piece of debris enter the cylinder, bounce around, and thus break the insulator?

It had been a recently supposed rebuild on his original engine at the time. I think he had a rod, bearing, or other internal cylinder issue that caused piston interference. There may be other damage in there. Like I said, he was driving it on his way back from Wichita and visited us before heading back to San Antonio and all was fine. The issue happened sometime after while cruising around San Antonio. He said that he intends to pull it apart sometime in the near future, we'll see.

Maybe 🤔 because guys like you can't spell my name correctly! Nah that's not it. I think his choice of words.😂
