I'm curious, considering your mileage, does your car still have the trap ox still installed?

Rough idle for the first few seconds on a cold start is telling me you have a weak or failed glow plug. Replace the plugs and ream the prechambers of soot. Every one of my 603s and 606s kicks over instantly and settles into a smooth idle on start up - EVEN with ambient temps near 0* F.

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.
