yall have any idea what would cause a tiny bit to come out like that? the cam was put in may 2021. I did have to add coolant a couple months later at the track but it wasn't leaking any (that I know of). the past week was the first time the car has been in super cold weather (for us in ga at least) since the cam. could that play a part? these cars have a coolant overflow, right? could that be it or does this look like an actual leak?

sorry for the ignorance, I'm not all that mechanically inclined

thanks for yalls input!
