Having trouble visualizing this. The AOS connects behind the throttle plate, which is way downstream of the air box. I would think that in case of an AOS failure, oil would get sucked into the intake manifolds. How did the oil find its way all the way back to the air box?

Imagine about ½ quart of oil in the intake runners and cross over tubes. As the Jägermobile is put on an incline going onto the tow truck, the oil starts flowing back into the throttle body (valve closed so the oil backs-up there for a bit) and then into the main intake tube. As the tow truck levels the flatbed the oil then starts flowing past the MAF sensor and into the air box. There is a drain valve at the bottom of the air box with two disk filters; the oil slowly flows through those filters and onto the flatbed.
