My daughter first notice the sound when she drove my car. I couldn’t hear it at first, drove home from Detroit to Indianapolis then yes, I could hear it. Come to find out I had very low oil, car kept cutting off when I’d come to a stop light, so I sat idle in neutral until the light changed. In that time, could I have damaged my engine?
Change the oil as soon as possible and check how much metal debris is in the oil. A good mechanic can tell you if there is an abnormal amount. If there is excessive metal int he oil, damage may have occurred. If there is no excess metal, I would say if the car runs fine, do not worry about the incident.
