Porsche’s direct injected engines, like the V6 in this Panamera, have fuel pumps that are driven mechanically by engine rotation and so have an oil seal at the opening of the pump where it is mounted to the engine. As you can see in one of the photos below, the oil seal has blown out of the pump, allowing motor oil to leak out.
