Hard to really tell, but this mixture of stuff is a piston, connecting rod, and wrist pin (MELTED basically)!! Piston came apart and slammed into the block leaving a huge bulge and crack...

 

Don't you hate when that happens? I've had rods come clean through the sides blocks before.

 

What had happened was over time I had a slow head gasket leak that wasn't noticeable. Coolant would slowly drip into one of the cylinders. Finally the cylinder took all it could and couldn't compress all the water and basically bent the rod, dislodging the piston and became a flying projectile in the motor. On top of that blown head gasket and what you've seen. Something to add, I noticed that my jeep wasn't starting right, so I thought dead cell in battery or something. I talked to a few people that asked if I noticed a lag when you started it and I said yes! They said everytime that 'lag' happened a little coolant would drip into the cylinder. Basically it was working its way up to failure and that's what it did, unfortunately on the interstate. So new motor going in...not what I planned lol but hey everyone has money to blow right?

 

Live and learn.

 

Indeed man. The thing was the temp gauge never once showed getting hot, always ran right under 210. And when this happened the temp gauge still didn't move, unless the Jeep shut off before anything registered
