This morning, I remote started my car like usual, and maybe 5 minutes later, i went down to the car, everything normal, i drove it up to the front door of my building and i went back inside to get something before i left. Left the car running. When i came back out 3 minutes later, the car was still running but it sounded like a metal on metal rattling sound. Not knocking, i know what engine knock sounds like and it was not that, this sounded like a consistent rattle within the motor. No lights on the dash, i just shut off the car and turned it back on again and everything was normal. Later, I checked the oil, the level was basically perfect and the oil looked normal. I have no clue what this was from but i hope its not bad
