What path did the oil take to end up under the left side of the engine?

Through the induction system over to the Air Box below the air filter... There is a drain at the bottom of the Air Box.

Ok Monday morning QB time

Are there indications you can think back on that may have been due to the AOS failing?

So when the AOS fails, does the car become un-driveable or in this case it was the oil leakage that scared you?

I was going to guess you lost one of your tire's valve stem caps

What in the world would cause your AOS to fail 4 times? Seems like maybe it's a symptom of a root cause problem that hasn't been addressed.

Operating environment being near sea level doesn't help as atmospheric pressures are greatest there and pout more load on the AOS internals.

I find that extended oil service intervals lead to this more than anything as acids in the oil reach levels that create diaphragm degradation within the AOS.

Jake,
Does running the oil level down one notch (from MAX), helps the AOS or not ..?

No, the AOS is not immersed in oil, despite oil level the operating conditions for the AOS are the same. It is constantly exposed to oil mist and vapors on one side and manifold vacuum on the other.

Not changing your oil frequently enough (not just mileage, but time) is a huge factor in this equation as well as the oil thats used. When chlorinated paraffin is included in the composition of an oil, the AOS hates it.

On top of that, the AOS is a low quality product and always has been. If it wasn't an emissions component I would have released our version long ago.

250k plus miles, i think his car has the highest mileage of any on the forum.

I have seen a picture of an odometer with over 300,000 miles from someone in Florida.

FloridaBill.

still on the original IMS. BUT...he drives the car heavily (does not let it sit) and maintains strict dealer service. I recall he fired his dealer service dept because the new mechanic did not pass muster on the telephone test of "how closely to you follow the letter of service manual" on spark plugs.

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.
