Bad head gasket?

[au6553]

I looked under the oil cap and there is a little white. The dipstick looks ok and it runs fine.
It hasn’t been overheated.
See attached photos.
Do you think I have a bad head gasket?

From this? No.

If you do a lot of short trips when it is wet or cold or both, you can get a little condensation in the oil cap and sometimes on the dipstick. If a longer run on the highway does not clear it, then worry.

Clean the residue with brake cleaner and then monitor.

If you are concerned and in need to have 99% certainty, I would suggest- replace oil and filter with a quality and correct oil(fcp, ipd sells those so you dont have to waste time researching grades, specs..). Drive it for around 1k with at least weekly good highway ride(20-30 min) as suggested above by sir scot850. After 1k suction a sample of oil(either harbor freight kit or a big 50cc syringe and a piece of plastic hose from your local hardware store) through the dip stick and send for analysis to the lab of your choosing(other members would be able to suggest possibly reputable names). But I would not stress at this time without all data. You also can rent/buy combustion leak detector and check your coolant for traces of exhaust . Good luck

I tend to do a lot of short trips around town in cool, damp weather and see this milky gunk often at the filler port of my vehicles. It is most likely not a concern IF YOU ARE DOING SHORT TRIPS.
