Next time...clean it well including inside the bottom cap and about the bleed nipple, and up to the top of the filter housing...then don't run it long. Start it up for 10 seconds and look again.

Keep doing this until you see first signs of oil dripping...or just replace the thing yourself: https://www.ecstuning.com/b-uro-par...IZwbIBcULpwGu-TlRVoSpoUilXxri9JRoCbN0QAvD_BwE
