not sure, but it seems that if there is oil build-up on the intake side of the AOS, that would be an indication.

so, did replacing it solve your issues, and what were your issues.

mine was basically heavy exhaust smoke on high revs under load and on startup after a heavy load incident, eventually some fouled plugs causing #5 and #6 cylinders to misfire.
I'll report back next week after I have replaced the AOS and plugs and tested.
