Well the other night i was on my way home doing about 40-45 in 5th gear when it happened. The car surged and I heard a bang, I was really close to my house so I cut across three lanes of traffic and pulled into a side street. That's when it happened again the car gave it last breathe banged again and died. Here's the pics of it, the worse part is that I just put it up for sale cause my wife got pregnant. oh well looks like I get to keep it now hahaha.

Your guess is as good as mine give me some ideas..

the car is down to just one beaner power now(my bro getting the head off)

Unless you took off the valve spring, I'd say the exhaust valve smacked the piston and bent a valve.

And you have spray, so all bets are off for what else could have been damaged prior to this event.

What plug - it looks like it has been removed to me.

Definitely something was bouncing around in the cylinder but the valves and pistons don't seem to be missing any material. So I would say that either the end of the plug fell off (was the plug OK?) or you sucked something in through the intake - done any work on it lately that might have left something hard in the intake manifold?

Looking at the pictures it appears as though he romeved the plug, and you're seeing the boss around the plug. It's just at that right angle to look like a melted plug.

Looks like it sucked something in. piston and valve's look to be in one peice

But something was bangen around in there for sure, looks like #4 cly

The plug had the ground strap touching the electrode,but was not melted (will post pics later after work),the exhaust valve is bent bad.
I had only sprayed the car about 3 times not even a half of a bottle, the blob is magnetic and I hadn't done to much around the intake the last I did was change the plugs and take off the nitrous kit (the plug before that was fine.) What is molded in the piston is what I'm confused about.

Well, you gotta figure out what caused the exhaust valve to bend. Broken valve spring maybe??

no because what beat the hell out of the piston was not a peice of valve. i would say def something came in through the intake

Is that cylinder #7?

Does anybody else think that 40mph in 5th gear might be lugging it too much with a cam that size??

Do you have stock gears?

Is it a nitrous jet? kinda hard to tell from the picture, but it appears to have a hole in the center of it. What ever it is it came thru the intake valve and beat the piston and bent the exhaust valve. How deep is it embedded in there?

In the fourth pic it appears that the exhaust valve seat is broke and missing a piece.

I don't know what caused it but just an observation. Why does one of the cylinders next to it look like it's burning rich and is full of carbon, and on one on the other side looks like it's buring perfect? The one with damage also appears to have been running very rich.

I'd have to agree with most of you. It looks like something came through the intake and destroyed it.

i agree with what he said ^^^

on the 2nd picture from the top, looks like your coolant passages are covered up by gasket material. I would be thinking that your heads were getting too hot and not getting any coolant, which could cause extreme detonation and pop your motor. Or am i looking at the wrong thing?
