2017 CX 9 OCV oil leak?

[moonj]

Just noticed some oil from here today.
I did some cleaning with brake cleaner, is it normal?
I see mentioned here: Oil patches on Engine cover - 2022 CX-5
Do I need to replace the part or just do some cleaning inside? Any instructions?

Update: Did researches here and see many posts like this.
So the suggestion here is just replace the gasket? Or actually need replace the "Engine Variable Valve Timing (Vvt) Solenoid"

Found some parts number so far:

• Engine Variable Valve Timing (Vvt) Solenoid (PE01-14-420A)
• Full cover and the 2 gaskets (PY8W-10-210B)
• The big gasket PY8W10235
• Can't really find the individual ENGINE VALVE COVER WASHER SEAL for cx 9 (This is for cx 5PE01-10-2D5)

Also see this video here:

Not sure if I can get it done, but I don't want dealer quote me a very high price for this

Thanks
