Well that was quick. I pulled the intake and found all this stuff in there. Pieces of head, valve, and piston ring.

Once I got the intake off I could look down and it was indeed number two that had failed. At first glance, it looked like the cylinder walls were not damaged. Now I’m not so sure, I got out my El cheapo borescope, and it looks like the wrist pin is missing so the rod was moving free in the cylinder smashing the remains of the piston. Mainly I’m concerned about the crank and crank carrier, if those are the only thing salvageable out of this engine I will be ok with that.

At this point I am absolutely 100% certain this engine is not re-buildable just by putting heads on it. Looks like it’s a 3.8 for me.
