Cam position sensor?

Cam position sensor?
Tracking down a misfire at various boost levels from 15-25 psi with fairly new Denso IKH24's that are 6 months old on my Evo IX.
Pulled the exhaust CPS just to look at it and a good amount of oil came out and was coated all over the CPS.
Since this is my first evo (20+yr DSM guy), I am assuming this is bad, but wanted to check with you guys.
Is the CPS housing where the CPS is installed supposed to be dry?
Could this cause misfires on boost?
Also, if anyone knows how to log the CPS with Evoscan, please point me in the right direction.

I did at one time, but there is nothing obvious to point to the CPS. It just looks like misfire with a big lean spike in AFR. I initially thought it was a fuel system issue because it would drive fine off boost. As soon as I got into boost, the motor would fall flat on its face about 80% of the time. Never got a CEL.

Ok, no biggie, I've been wanting a COP system for awhile, so this is a good excuse to build one. If it doesn't fix the misfire, I'll replace the exhaust CPS.
Thanks for the info!
