My 2014 challenger is leaking oil i was told its was the oil filter chamber , what does this mean and how nuch will this cost to fix

I’d request some uv sensitive dye be added to oil so the actual leak source can be pinpointed using a uv light ..The dye will fluoresce brightly in the presence of black light. Pinpointing location of fluid leaks of any kind can be very deceiving as the actual source is typically illusive .. Gravity and engine configurations / components make a huge difference.
