on start up in the cold 20 to 30F (or -6 to -1C) with the cold start pulled, i get steady white smoke for about 5-10 mins until the car is warmed up.
question is... is that too much? or there shouldn't be any at all?
i think my cold start needs to be adjusted anyways.
Are your glow plugs good? I get white smoke only while I am cranking. Once it starts, the white smoke is gone except for occasional puffs right at the exhaust pipe. And this is at -15C.
yeah they are all brand new from the engine rebuild.
Check your timing, also your kold start solenoid on the pump (the other wire, not the shut-off solenoid) it advances the timing slightly when the pump is cold...if the smoke dissipates after 5 min of good driving (not idling) I woiuldn't worry...
I run my pump at 1.02mm, so with the advanced pulled it sits around 1.05mm.
I also run Bosch Duraterms, with the afterglow feature. I get smoke for the first 5 seconds of running then it is gone. I usually afterglow for 30 seconds.
If it is really bothering you, I would suggest the Duraterms with a manual controller. The afterglow really helps with cold combustion (keeping the precups at 400F, instead of allowing the combustion to heat them up)

yeah if i drive it right away it usually stops smoking with in 2-3 mins.
i think my pump is set at .90. i can't remember. i have the tool so maybe i'll screw around with it and see if i can make it alittle better.
finshed the rebuild in october.
they were bosch plugs.
no air in any lines.
I watched my tailpipe this morning on first startup at 30F, a nice puff of wonderful black smoke
and then it instantly cleared up and only puffed more black when I popped the go pedal. There was no white smoke at all.
Once when I installed the IP I had the belt a tooth off and it smoked white but it also ran horrible. From what I've read most people have good luck with .98mm-1.00mm.
not sure if it's the case yet until i pull an injector and look, but would upside down heatshields cause this?
