What happened to my engine???

[Old Henry]

Just opened up the oil pan to drain the oil out and this stuff came out.



Here's the story:

On April 4th I picked up Betsy at her assisted living center in Old Henry and took her to her 94th birthday party that was just around the corner from my place then went home. When I pulled into the garage I heard this clicking sound under the hood. Opened it up and it was coming from the back bottom of the engine on the right side. Wondered what it was. Drove to my office and on the way home the clicking turned into a knocking. Then, about a block from home coming up the hill something came apart inside the engine with a real bad sound. After the initial bad sound the sound was mostly like a bicycle chain loose inside rubbing on something. The engine was still running but I immediately pulled over, shut off the engine, and called my wife to come tow me home. (Yeah. She loves that.) Tonight I opened up the drain plug to drain the oil out to see if I could see anything up in there and out came all of these pieces that look to me like parts of a piston blown apart.

Saturday I'm pulling the engine to take off the oil pan to see more but just wonder what you all think is the damage and, more importantly, what caused it. The engine was totaly rebuilt my a master 3½ years and 30,000 miles ago.

What do you think???
