Oil leak

[rgnbull]

Anyone seen this issue before? Few problems, got a low oil warning light. Took off the bottom panels and found this...looks like the o ring from the oil pump drive shaft was leaking at some point but it doesn't look like an active leak. Had my mechanic top off the oil and added a UV leak additive. Drove it a couple hundred miles and didn't seem to be leaking anywhere even under UV light....odd.

Months before when I had the passenger rear wheel well liner off I noticed the front axle lift accumulator tank had what appeared to be old oil building up. Looked around and couldn't find where it was coming from.
