Does anyone have experience with the engine siezing? There was plenty of oil and the dealership told me that it looks like a valve spring failed and caused the catastrophe. Short block and pistons being replaced, ancillary parts being rebuilt or reused. Any other concerns here? Had I been 5ft further, I would have been in the middle of a busy road. Anther 10 miles and I would have been on the highway. Kind of freaked out here...
