Need help identify an engine noise.
Need help figure out what this noise is. Third time I've started the car. Frist two times the noise wasn't there. Only ran for 30sec each time. Noise is there right from startup now. Sounds like metal on metal. Can't really pinpoint where it is coming from. Best guess is towards the back of the motor in the middle. No engine codes and smooth idle.

I would at least remove the drive belts as a test only to eliminate that possibility of a HB or belt noise. But I think you have a faulty roller lifter. If you pull the valve covers off and start the engine, and the volume of the noise increases, that would narrow it down to the lifter issue.
What's the full history of your car, mods, mileage so on.

Ran the s/numbers on the Computer, is for a 08 vette
Was thinking bad lifter myself.
Going to try the belts right now.
