Oil leaking around recently installed 97+ style CAS, I want to verify....

[16g-95gsx]

On my recent 1g head swap I installed a 97 CAS. The sensor I have installed as follows: The housing bolts to the head, the cylinder has a brand new OEM oring installed inside it and then the bolt for the sensor itself slides through the sensor and into the cam. However I notice that I have oil leaking out from the housing, so something isnt right. Can anyone verify how this sensor installs exactly, and seals off itself from oil? The Oring apparently is the only piece that seals the sensor, and Id definately like to verify where that Oring sits as well as anything else pertinant.

To help the diagnosis I removed the CAS and here is a picture of the cylinder with how I have the Oring currently. Please tell me if this is correct or not.
