I noticed that my 2006 G35 has excessive moisture in the oil as the oil cap has a good deal of white condensation underneath. The car is driven short trips but I have not had the problem before.
I took the car for a good drive on the highway for 40 minutes but the condensation is back within a week. Coolant is clean and no signs of contamination or coolant loss. The dipstick is clean.
What would be causing this excessive condensation to build up?
