Did you change only the AOS or you changed some hoses at the same time?

Me? I just changed the AOS, the hoses all seemed fine. I do plan on cutting open the old AOS to see what fails, but I am not in a hurry to do so at the moment.

I was looking for some AOS pictures once and came across this post on Rennlist. It shows good detail of the inside of a failed one:

I think there is a diaphragm inside that fails, the aos is just a glorified PCV
