anyone ever replace the PCV valve?

[Gilles]

JFP, how often does the PCV valve has to be replaced..?

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!
