There is a collection of oil that leaks down into the bottom of the cylinders over time and it gets burned out at first start. Usually blue in color though. And normal/typical for the design of the engine. We all do it to some degree...sometimes depends on the length of the stay and the angle we parked on.
White smoke that covers the car can be the sign of a failed AOS tank or bellows attaching it to the engine. Does it look like the first picture?
