That oil in the intake is pretty normal too, believe it or not!
The way the engine breathes combined with cold weather condensation, moisture gets mixed in with the oil vapor and creates an oily sludge in the intake.
Best to clean it out after the cold weather, annually. Clean the carbon off the throttle butterfly and get the oil muck out of all the breather plumbing at the same time.
