Hello, I noticed an oil leak under the engine, I think I identified where it comes from but I don't know which piece it is and what to change. Here are some pictures where I have indicated the plug I think is leaking. Thanks for your help.

That's an electrical plug. It won't leak oil, only electrons.

I would guess your valve cover/gasket is leaking, and the plug is getting wet.
