Ive seen small casting flaw holes in cylinder heads or intakes suck in oil when I was a dealership mechanic. Its rare but it happens

Check at the base of your spring pockets.

Yup, pull the intake if needed and look at the backside of the intake valves for any "puddled up" oil, or oil tracking in the runner. Then check the angles to ensure they match.
