bolt

Not tying to be stupid, just playing the bad guy..

I have been in some top notch builders shops and seen what they do. I am not saying it happened here, but something to think about..

Some of the bigger well known shops are very busy and they do not have time for a lot of detail work. It takes a long time to stretch each rod bolt. What I have seen happen is they will do one bolt, calculate the required torque and do the other 15 bolts with a torque wrench. I can tell you first hand this does not work…

Next, like was mentioned there is slim chance the bolt got missed, but IMO very unlikely because I would think that would have showed up on the first pass, But stranger things have happened. I mark all my bolts with paint marker as I stretch them that way none get missed…

Another possibility, maybe the bolt came in contact with a chemical that reacted to the base metal, something like brakecleen.

Could be a material failure…

A lot of times in this type of failure the true cause is never found…
