Lingering fuel smell in oil

First noticed the smell of gas in the oil a few weeks ago. Went ahead and replaced the fuel pump since I'd learned the diaphragms can leak into the crankcase (no record of when the PO last changed it so it seemed like a reasonable place to start). Changed the oil and filter. Didn't notice any significant increase in the oil level on the dipstick.

Fast forward to now: I've got this lingering fuel smell in the oil. The smell isn't as potent as before. Perhaps my nostrils are just being overly sensitive since I know that the diluted oil could be the death knell for the slant?

I have not done any real tuning to the carburetor since I got the car (I know, I know. I need to get to that). I suppose it's possible it could be dumping fuel in the intake, however I haven't noticed horrible mileage, the car fires up with ease in the morning, and there is no sign of black smoke out the tailpipe.

Anything else I should be looking at???

Car is a 68 Valiant (based on the engine color I'm thinking it's been replaced with a 69 slant at some point). Single bbl, no headers, basically stock. Doesn't get driven a huge amount, but when it does get driven it's generally fairly short trips.
