Feels good to fix it yourself, doesn't it?

I would skip the lick test (yucch.) If the coolant level isn't
dropping it's OK. The six mile trips are a problem though. Having
that much condensation in the crankcase is bad. You should change the
oil now and then start taking it on a 20+ mile ride at least once a
week. Even then, you should change the oil every three months
regardless of milage.
