For ticking lifters, run half a quart of trans fluid in the crank case 50 miles before your oil change and a few good highway runs with it @2.5k - 3k rpm. Your lifters are probably plugging up and aren't pressurizing properly. That low of mileage is just screaming "I'm rarely driven, help me breathe". Trans fluid treatment won't be an overnight miracle, takes time.
If I was bored and trying to eliminate some minute idling smoke (unburnt fuel) here's how I'd start (considering your mileage):
- Diesel Purge a hot engine (or run a mix of 70% kerosene/30% diesel )
- Get your injectors serviced (pop tested, cleaned, etc)
- Check, set injection timing
See what happens from there. I'm assuming you're keeping up with fluid, filter changes throughout the car.

Thanks, already ran 2 cans of diesel purge through the system using an external fuel tank, didn't make the slightest bit of a difference. Do your early 603 start that easily, even without afterglow? Too bad I just changed the oil or i would have liked to try trans fluid. Is it likely that i need to balance or change the nozzles at such low mileage? I haven't checked timing yet as I cant afford to buy an a-b light yet, i'm hoping that not the issue although the owners manual says to check timing at 30k miles and I have no way of knowing if that was done by the original owner. i also read that the lift pump can cause idle smoke, but would think that would lead to rough running under heavy load, which i don't have, but the engine did stall after changing the fuel filters. How can i test the lift pump?
