Bearings taking out an LT4 with only 3,000 miles is no joke. Once they go, especially on a high-performance engine like that, it's game over fast. The fact that it already had shavings in the oil means the damage probably started a while before it was caught. Bearings are such a small part but can cause catastrophic failure when they fail — especially on engines like the LT4 that run high pressures and tight tolerances. Hope it’s warranty-covered, but still scary stuff to see firsthand.
