I have some updates on the smoke situation. Since my last post I have rebuilt my injectors using monark nozzles, and I personally balanced them and spray tested them before install. The car idles very quietly and smoothly but the symptoms are exactly the same. Rough running and smoke for the first 15 seconds or so, only on the first start of the day. And smoke at idle, hot or cold, always. Sometimes the smoke is hard to see, but in the right lighting conditions you can see it clearly. Also when revving the engine it continues to smoke, but stops for a second when backing off of the throttle. Here is a list of what I have done or checked:
1. Chain Stretch, 0 degrees of stretch
2. ZERO blowby from the oil cap
3. New Balanced monark nozzles
4. turbo has no shaft play and compressor is oil free, did not check exhaust side
5. Hydraulic lifters have all been checked and are good/quiet
6. No oil usage within the last 2700 miles
7. Alda holds vacuum pressure
8. EGR pipe blocked off
9. I did notice some oil in the intake pipe
10. New Bosch france glowplugs
11. Four cans of diesel purge, until it ran clear, this actually seemed to help cold starts the most.
12. Prechambers look good, no oil or damage.
13. I did a quick visual check of the timing pin, and it was where it should be using a mirror, but I dont have access to the tool so its not 100%.
Not sure where to go from here or what else could be causing the smoke.
