I need a second opinion on a motor knock. I ran my car at the track and it ran great. On my way home my check engine light went on so i pulled over and checked it out. Was pulling a bank 1 is running to lean so i got it home and turned it off. In the morning I turned it over and a horrible knock came from the motor. It sounded like I threw a rod bearing. Not sure though, any input?
