Strong fuel smell coming from crankcase vent hose

[RegionThr33]

I know this usually means bad rings or piston ect. but I don't understand why it just started now that it's 4° F outside. Just coincidence? My oil smells like straight up gasoline. It wasn't running rich before.

Faulty or injector stuck open?

If it is running good this idea doesn't make sense.
