Any updates?
I agree that it looks like it came from the oil fill hole. More than likely it was spilled when they filled it.
But just in case, there’s a wire that goes through a rubber grommet in this location that could leak.
Maybe there is a leak for the second gear lock out thingy? Put a screwdriver and a 10 mm socket on these to make sure they are tight
There is a o-ring in this location for the oil cooler. It could be a possible leak.
I still don’t see how these areas that I circled could be a possibility unless you were driving fast and there was airflow pushing it up higher.
