Will any old Garrett T3 rebuild kit work or does it need to be specific to a .45 trim or even specific to a Mercedes?
Other thought I had while talking to a friend, if oil is getting out between the turbo and the intake manifold, aren't I losing air and pressure there as well?

Yes you would be loosing a little pressure, but not enough to notice any lack of power. Replace the sleeve Orings when you have the turbo out. Yes you should rebuild the turbo, even if you keep the ARV cold side. The Mitsubishi turbo I had, I am sure was very worn out, and much worse than yours. I imagine the oil in the air stream does not mix with the air at idle in yours (stays in the turbo and manifold), but may be forced into the intake during a boost situation (reason for smoke at boost, not at idle). That may be why you have the opposite situation as my Mits. Also, on the Mits, the outlet from the turbo faces down, and the intake manifold is lower than the turbo. That is probably why all the oil getting past the seals goes directly into the intake on the Mits. The 'Benz is not quite that way.
