Yes, there is no signs anywhere of a leak. Really looked hard, put it on a friends rack and we both looked.
This is the first time I have noticed that the Fender side of the tank was almost empty. Also, I have a new cap coming today to try that first.
My Blackstone Labs oil reports indicate a rising Potassium trace amounts since it had 35,000 on the motor [was normal at 35k]. The normal Unit averages for this LML is 5, at 48k it was 9, at 55k it was 12 and at 63K it was 32. However the corresponding Sodium [another marker for a coolant leak] was not high, actually normal. TBN was 7.1 [normal with some additive left] Also, my top hose was not hard this morning. Got my fingers crossed here...
