Pulled the valve cover today anyone ever see this stuff?

Everything on the engine looks clean , but the gunk on the valve cover can't be good . Doesn't smell like gas , has the look of baby food , a little watery. like steam was mixing with the oil spray on the valve cover? oil on the dip stick looks good , any thoughts?
