White smoke

I installed new gpr cause old one was sticking when cold. Glow plugs are reading ok at plug on valve cover and all seem fine. New orings on injectors. Seems to start fine when cold, it just looks like a cold 1950 something diesel smoking for 15 minutes. I had the injectors tested while out and they said they recommended replacing them cause they were down about 10 percent. They said they woild be fine at idle. Well with only 120k on them i didn't change them and stuck with new orings only. I just cant figure out why it smokes so bad on start up and runs great all the rest of the time. Could the glow plugs be actually burnign shorter in length like the old days and causing the problem. Also I know NCHornet has a test procedure but can't find it. Please show link if find it. Please help

So I installed new motorcraft glow plus today. I checked my old ones with a bettery charger and they all seemed to light fine. Anyone have any ideas why the white smoke.

white smoke is unburned fuel, could be tired injectors, does it do it only in the cold?

Diesels will smoke white/blue when they are cold. Its unburnt fuel do to low combustion temperatures.

What do you mean injectors were "down about 10 percent"

Ya it only does it for the first 10 to 15 min. But its nastier than anything i've seen. It runs great though. I was told the injectors are down about 10 percent, but when the truck is warm it doesnt do it. And I still get 15 to 17 miles a gallon. I just have a hard time thinkin injectors could do it. What ya think.

Ive never heard anyone say anything about injectors being down a %. Sounds like he don't know what hes talking about. What are the outside temps when it smokes?

Might just be normal. Mine smokes like hell when its real cold.

Mine does the same thing man. Drive me crazy. Been smoking really bad with the cold weather lately. Will go away once the truck temps warm up. But it smokes no mater what the temp is outside if engine is cold. sounds like me and you have the same problem
