You might want to see if your C7 had these metal shavings as the outcome is as this one magazine states and engine failure requiring a engine replacement

For starters, the LT1 small-block V-8 introduced with the C7 lunched itself at 6000 miles, necessitating a complete LT1 replacement under warranty.
Our forensics lab was unable to assist in dissecting the matter, but an investigation by GM pinned tentative blame on a piece of metal debris (likely from a bad oil filter) that worked its way into the oiling system and wrecked a connecting-rod bearing, which created even more debris that damaged the engine’s bottom-end.

Given the LT1’s tight tolerances and high-performance design, it didn’t take much to upset its workings.
We’ve heard of a few similar accounts throughout the Stingray community and GM says it’s aware of the issue and is analyzing its manufacturing process for a root cause.
Our car was returned quickly and as healthy as new, but—just to be safe—we sent the car back to the dealer after 1300 engine miles for its first scheduled service at 7500 overall mile
