[QUOTE="mandkole, post: 1090692, member: 4630"] ^^^mine looks like that vid for the first couple minutes on every first start below 70 F. I have suspect glow plugs, no intake heater, but otherwise the motor is very healthy. The smoke goes away when it warms more. Ive been observing other things as well--the PW is consistently at 1.5-1.8ms in those situations. With the exact same scan gauge, I recorded PW of 1.1ms on the old OBS at idle out of gear. It had stock nozzle ACs. To me, for larger nozzles (with less fine fuel control and more output), that just seems like too much PW. When the truck is hot, idling in gear on the brake, the PW is 1.8ms. In park, its 1.4ms. What does everyone else see? Is this just a tuning issue? [/QUOTE]
