I bought my gaskets directly from Cummins, and the parts guy there told me about the O-Rings, or I wouldn't have known about them.
Call up Cummins in your area, they should be able to get you the o-rings. If they don't know what you're talking about, you could always get them shipped from Cummins NW in Renton WA, where I got mine from..
I wouldn't use a generic hardware store o-ring unless you know that they are made of Viton. Regular rubber doesn't hold up to the heat and oil exposure as well.

Yep! Like Infidel said.. The vac pump exhausts into the accessory case and that vents through the crankcase to the breather tube.
Ever since I bought my CTD, it had a pretty good plume of oil smoke issuing from the breather tube. I used to think that was normal...
This year I stumbled across a huge vacuum leak right at that little rubber coupling elbow where it pushes onto the steel nipple of the vacuum pump. The bottom of the rubber elbow had a hole sucked in it and it could NOT be seen from the top. I felt it with my finger while the engine was idling. (that vac pump can suck a serious amount of air!)
Thankfully, my engine's blowby is now a whole lot better than before!
AND it looks like my oil consumption has apparently gone down too!
