Flush the coolant with a propylene glycol based coolant soon, as it is less damaging to engine internals in the event of contamination.

Well, except as you will notice, Glycol comes back at zero, which would preclude a current coolant leak.
Can't glycol can come back at 0 but still have a coolant leak which will show as elevated antifreeze additives. I have had this before in my 3.1L but that was with Blackstone's glycol testing. Maybe Terry's lab uses a method that is different enough to always detect it but I doubt it.

The absence of glycol does not mean there is no coolant leak. With small leaks like this one the glycol is evaporated out of the oil faster than it's going in. You've got a coolant leak.
