I am on my third AOS (80k) and after reading this post, it seems that this could be cause for the short lived AOS.

I already bought the two accordion hoses that connect to the AOS, perhaps may be a good idea to buy the PCV valve and replace it at the same time.

Question: Does the lower accordion hose connects the AOS with the PCV valve..?

Thanks in advance!

We do it when they start to look nasty, or to stick. If someone has suffered and AOS failure with lots of oil in the intake system, we always change them out after cleaning everything else.
