Can the Doser leak coolant into the exhaust? After its shut off the exhaust flange will be wet with coolant and when you start it it will white smoke for a short time but if it sets 2 days or so the coolant will dry up and no smoke on start up. It uses about a quart in a week around 2000 miles.

I had one leak coolant on an ISX. Pressured it up and it had a verrrry slow drip. Very uncommon but can happen
