Ender 3 v2 neo leaking oil????

Hello all, I was examining my printer over and found an odd residue that was laying on the metal bar under the z axis stepper motor. My first thought is that the stepper motor might be leaking oil. Im really not that sure to be real. Can stepper motors even leak oil? and if so how much? Has this ever happened to any of you guys? I have never seen this happen before.

can somoene please respond? I need to solve this issue and this forum is terrible in the sense that literally no one responds to my posts. Worst. Forum. Ever.
