There is a tendency for water vapors to condense in the top of the oil filler especially if the car is driven for short distances and the oil never really gets hot or is never driven very hard something which Heinrich would not be familiar with

H,
I'll take her for a spin and blow the cobwebs out for you.
That will get rid of the "sludge".

THat is excess engine oil sludge. I see that alot in the TOYOTA's I that come in on a day to day basis ( 3.0 v-6 ) camry, solara, sienna, ect . mainly comes from high cylinder temps and lack of oil canges at a regular interval, When you see it at the upper end, Its is usally worse at the lower end. The oil passages get restricted as well as the oil pick-up. Oil starvation starts and Its all down hill from there.
With the Toyota It started when they switched from Iron block to an all aluminum block and eliminated the oil cooler.Also the pcv chanber in the valve covers were redesigned. I guess they felt the aluminum would be a cooler engine, That coupled with the forgetfull people who did not changed their oil reguarly caused the oil to "gell". There is a sort of "silent campaign" still going on through toyota for those veh. If it is "gelled" through toyota, I just takes "proof" of 1 "lof" per year as proof of maint and the dealer is self authorized. they will replace the valve covers, desludge the upper end, valve seals, pull oil pan and desludge.
Hendrich, Not having the service hostory of the car, expecially with lose mileage the sludge could be normal engine oil break down. the PO may have only changed the oil at the factory recommended intervals...for some of us that is several years if we trac by miles. The quality of the oil also plays a role.

I had a friend who bought a 68 Camaro in high school, perfect body, with what everybody thought was rod knock. He got the car for a song.
Turns out the oil on the car had never been changed, just added to. He changed the oil, ran some seafoam or rislone through it, changed it again, and voila! the noise went away. Drove that car for years.
It couldn't hurt to just change the oil and dump some cleaning crap down there, and let it idle for awhile, and then change the oil again and see.

Dump some ATF in with the oil, drive it for 50 miles or so (not much more than that), and drain and refill. The ATF's cleaning properties will clean a lot of that stuff up in a jiffy!
