Engine bolt failures
I saw this page today and found it interesting. I see quite a few examples of this at work.
fastener failures

but never having had an internal fastener failure inside an engine myself, I am curious as to what you have seen with rod bolts and such. Or is the carnage usually too great to really tell?

Carnage was too great for me to tell. Either I spun a main, or the rod bolt failed. Crank was broken in 3 pieces, with 1 rod bolt's nut off the cap. And this was in a 5800 rpm 12 second Olds.

It is also why I believe every dedicated bracket car should have a diaper.

Spun bearings will show heat! So its tuff to miss these! No black and purple colored parts anywhere would indicate a catastrophic parts failure first then pow!
