Yellow, Mustard like, stuff on oil cap??
So I have searched about this stuff being on the oil cap being "condensation" but pages have said if it is condensation then its from driving short distances but I drive 40 miles a day for work. And the oil on the dipstick is clean, so what else could it be? I have cleaned it off a few times but it still comes back. Any suggestions?

Grey Poupon or Honey Dijion????
That's what I'd like to know....
Seriously though....40 miles round trip is can still be a short distance driving, depending on what speeds you're going and how hard the truck is driven....imo...
