Hence the title. After opening her up this is what I found. The funny thing is the broken off piece is no where to be found. Heads where not damaged it all.

I had an old Cobra II that I did a engine swap in way back when. The mechanic that pulled the old engine took off the heads and found the imprint of a bolt in the piston. Bolt was nowhere to be found and the engine ran OK for what it was. Never figured that one out...

Broken piece nowhere to be found? That doesn't sound good.

yikes Must have broke and slipped out the exhaust valve right away. Amazing that you didn't bend a valve or damage the heads.

I had a small hose clamp fallinto the #7 cyclinder on my 5.0 and didn't know it till it bent the pushrod, cracked the head, destroyed the top of the piston and chipped the top of the cylinder wall. Some of it was inthe combustion chamber, some of it was MIA and some of it is embedded in the top of the piston to this day.

If it broke into many little pieces, it could have slipped past the piston side and be sitting in the oil pan. Drain it and feel/scrape around in there.

Thats not good.

It looks like a dirty frying pan that has been sitting in the sink for a week.

Not a nice picture

Yeah, I had a little scare when I was swapping the plugs for my blower. I actually had a pebble fall into the hole but it was big enough so it didn't go clear through into the cylinder.

Ouch, at least the heads were safe
I had a kid in my auto tech class last year who threw a rod in his thunderbird. We pulled the engine and after we cleaned up the antifreeze flood, we got the block apart. I think there was one intact connecting rod and no intact pistons. They were all broken in half like crackers. There was a nice sized hole about 1.5" across where the piston had punched through the side of the block and a big chunk of connecting rod in the oil pan pickup

When I blew my pistons the edge between the rings was completely gone. All I have to say is not this time.
