Oh No The Jägermobile Broke Today!

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.

Jake, I change my oil more often than average, between 3500 and 4000 miles. I am at the coast and driving along elevations that vary between 50 and 200 feet above sea level. What oils contain chlorinated paraffin, or should I ask what qualified oils don't have chlorinated paraffin? Thanks

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.
