u/Eulogioo

Hi not mechanicly incline person here and wanted to ask for some help regarding my issue. I have a Hyundai Accent 2015 1.4 kappa engine that recently overheated. When it did I checked the coolant reservoir and it overflowed with brown coolant.

I had it checked and mechanic suggested a top overhaul. After having it opened up, we found that coolant was leaking into the 1st cylinder mostly and there doesn't seem to be any damage to the head gasket from the picture below. Is this still a head gasket issue or something else?
