Oil changes at regular intervals. In fact the valve cover was last taken off in the past year, and I just changed the oil in the past 2 months. It's got under 155k miles on it. Does this look like sludge from excess moisture, or from overfilled oil?

A few months ago, about 1-1.5 liters of oil "disappeared", dipstick was completely dry so I added that much. Within a few days it was showing as way overfilled on dipstick. Is it possible that oil was getting trapped somewhere? After this last oil change I've pulled the valve cover and discovered this. I scooped it up as best I could with paper towels, and drained some oil. It seems like a very fast build up of sludge and I'm going to pull the cover this weekend again to check the condition.
