Turbocharged engines are known for smoke on startup. It's not at all unusual for turbochargers to seep some oil into the exhaust. It's also common for oil and oil films to build up in the intake. Parking on an incline can make it worse.
It's good to remember how a turbocharger seals the exhaust side. There is no "lip" seal, "O" Ring or other positive sealing device. There are metal "rings" (sometimes just one) that look like small piston rings, and they prevent gross blow-by into the turbo and gross oil loss out of the turbo. Oil can find it's way past this seal and drip into the exhaust scroll. Where it burns off upon startup.
It's good to keep in mind that a quality synthetic oil will help prevent hot side "coking" and subsequent smoking.
The last picture shows the coking that happens with conventional oils. Most modern turbochargers are very tolerant of this (designed to accommodate coking) and will not fail quickly on cheap oil. Just keep in mind that the problem is in essence, completely prevented with a high quality synthetic, changed regularly.
