Understood and agreed, but I think your point is one of semantics. GM will be fully replacing the engine and all damage components, which will repair my car. Could not be happier with the news and a not trying to pick nits on your response picking nits 😉. If my response posted in excitement at the news was ambiguous, my bad.

My bad for wording it like I was picking at your use of term "repair". It was not my intent to suggest that you did not know it was going to be a replacement. But you were hopeful about getting a "root cause" assessment". I was asking if the dealer will even do a forensic tear down in this case. I really don't know. That's something you can find out when you meet with the service rep.

No joke, #2 question I have for the service manager. A total assumption on my part: it will not go back to the neutered break-in process ecu parameters - as I would think it is a mileage-based programming feature.

It is a "repair", whatever is done to get it going again, is a repair.
I do not think any dealer does any forensics of this type of failure, factory will want the engine back for any such forensics, to try and determine where the engine build went south.
I was just hoping to see if it made a window in the cylinder block when it puked the connecting rod, my bet is that it at least broke the block to some extent.
And, I've been wondering where the rest of the con rod went???
Maybe laying in the belly pan, or is it laying on the street somewhere?
I doubt the pcm will be reset for a new break-in rpm setup on the tach like in a new car, @OC8 will have to watch that himself.

Along the same lines..
I wonder what else will be changed along with the engine?
With an old engine it would be pretty straightforward... but in the digital age, I have no idea what else might be involved.
Software update?
Ancillary systems...or will they be moved over from old block?
Anything to do with the DCT?

Now, I could see a scenario where the input shaft on the trans could be damaged if the crank got broken and cocked sideways.
They won't know about that until they get the engine/trans out and separated.
