Day length formula: (Did you know that it becomes a triangle wave at the (ant)arctic circle?)

I can't figure out what's leaking on my '73 F250. Shows up slowly at the back of the oil pan. It's pretty clear because I've recently changed fluids and scrubbed the engine.
It was definitely brake fluid for a while after it was overfilled but that has evened out. The oil level is steady after when checking every 10 miles or so.
I think anyway... hard to know with these ๐ฌ
I'm doing experiments with short attention-span students and code. Starting with python, and, oddly, now working in BASIC. As a C programmer of 40+ years, I find this aesthetically and pedagogically displeasing, but I am delighted to see them getting fully absorbed in writing
130 PRINT "You have been eaten by a bear!" : GOTO 900. Yes there is spaghetti, but it's their spaghetti and they seem to take delight in debugging it. Python will come later.
