white junk on oil filler cap
I changed my oil ('97 F150 4.6L) this weekend after the usual 3000 miles and noticed kind of a white slime on the bottom of the oil filler cap and the inside of the filler tube. It wiped right off though, not sticky at all. Any idea what it might be? Please don't say antifreeze. I thought it might be foam from the oil on top? The oil looked good in the pan, no streaks or odd colors. I don't have a black light to look for antifreeze though. By the way, I use Quaker 5W30. Thanks.

While you cannot categorically rule out antifreeze -- it is more likely that it is water condensate.
In winter months, it is normal for areas of the engine that don't get hot to condense water -- which can often resemble a whipped-up version of Vasoline Jelly.
On engines where the oil filler cap is mounted on a raised tube which is in line with radiator fan air -- rust often forms on the metal of the oil cap.
Running the truck at highway speeds long enough to heat the oil to something above 212 deg F -- it is the usual 'fix' for this type of problem -- and is one of the reasons why winter driving is often considered 'severe'.
Wipe the slime -- change the oil -- drive it -- and rest easy.
