Bob's pictures really make the story come to life. Great job!
Photo came in loud and clear with Safari on MAC.

Wonder when that case was manufactured?

Might not want to blame the case just yet. Hopefully we'll soon see some photos of the internal bits.

Looking at the case crack image, it appears that the connecting rod hit the case. (download image and enlarge)

Cannot wait to see images from inside the case.

I think it will get some of your attention when you hear the root cause--

...and that may be tough to determine...which came first, internal failure or external case failure...case separation certainly would affect internal clearance specs...a good case should be able to withstand internal failure...

In any event, metal failure internal or external, can be attributed to aging, that's why Lycoming won't overhaul an old engine. I think the cut off is 22 years.

Just like me, at age 78, some parts are beyond salvage.

New ECI IO-371 engine with less than 500 hours. Crankshaft is in 2 pieces and one counterweight is no longer attached to it. Either the crank broke first or the counterweight flange on the crank broke first----#4 rod is in 2 pieces (I am guessing it broke after the crank). ECI doesn't seem to care what failed and why.

I'm sure Greg will chime in here, but like Jon said, the big thing that holds the rod things is in 2 pieces

Greg said it definitely got his attention.
