Without looking at all the rest of the rod and main bearings, I cannot say for sure, but it sure looks like the "standard" #2/#5 rod bearing failure to me.

Remember, EVERYTHING is "Cause & Effect" and detailed forensics helps determine both the sequences and cause of an engine failure.

LOL

Steve was explaining the forensics involved in determining why an engine fails/blows to me just a couple days ago.

it was part of a sermon on the correct way to rebuild a 911 engine.:D

in the process of get my case stripped to the rods/case/internals and the heads so I can ship to Steve to rebuilt for my 78 930. I KNOW Steve is the guy who can help me avoid having to post such carnage.....
