The mystery of the missing oil?

Hello all. I've been enjoying my dart all winter until today, when I briefly got an oil warning light while stopping. It came on for maybe a second.

I checked my oil after I got home and found it was gone! Just a smudge on the end, under the low end, black, and smelling of gas. No coolant or milkshake.

I haven't noticed any blue smoke even once since my oil change (less than 1k miles ago).

Any guesses?? I have heard the PCV valve could be a culprit but that would be hard to believe....

PCV is currently hooked to (I believe) the correct port on my holley 1920. I filled the oil and checked about 100 times in the first few days.... I'm baffled
