Moisture out one tail pipe, and a bit in oil. any idea?

You could always have a combustion leak down test done.If you have a problem with a head gasket or crack , I cant think of a better way to test for it .

I would keep a close eye on the coolant level, and if it goes down without any leaks I would have this done asap
