Your oil air breather tube is post air filter (so it gets filtered air) which
is usually warm and cools down with the engine. Any "moist" air shouldn't be
in significant quantities at that point, unless you are somehow getting water
in your intake air (like a water injection system). Condensation from normal
operations should be almost nil. You shouldn't be seeing it in a filler tube
unless the cap is defective. Without seeing the oil from the engine, I
wouldn't jump to a condensation conclusion so rapidly.

Since I have a V6 and don't have this problem :-) I'm not getting very much
into this, but water vapor in in the air. Unless there is a total vacuum
inside your valve covers there will be water vapor in there. Then all it
takes is a heat up/cool down cycle to cause condensation.
