and oil loss on dipstick?? havent seen you mention you checked level yet????? mine had that under cap but was stored for 4 months, so a good 30 mile drive got the moisture out the oil, and no more condensation.. take the breather filter off, attacj a hose and put hose into a coke bottle, got for a drive good 25 mile one so oil warms up and condensation goes.. make sure u clean filler cap before going for the drive.. once had the drive, check coke bottle to see if any oil is in their, then check filler cap.. only once that happens can u rule out condensation// and look towards headgasket
