The car only has 15k on it currently. Thanks.

What you are telling us sure sounds like a head gasket issue to me. A little moisture on the oil filler cap is normal especially if you just take your car for a short ride. Moisture gets in your engine all the time and because your filler cap is vented, that is where the moisture will collect.
