Oil leak at hight revs

[Jhenry04]

Hi guys,
I have noticed an oil leak of about 500ml of oil per week of daily driving, but only from revving over about 5k, the past couple of weeks I have lost no oil and only driven under 5k. Does anybody know what could be leaking? The oil can be seen in my attached photo.
Thanks.

Have you overfilled?

No mate never. I’m normally sat at about 3 quarters on the dip stick.

Potentially main seal, I would give it a good clean up with some brake cleaner and try and see where it comes from.
