If your getting smoke out the tailpipe after its already warmed up and your driving around it is not a glow plug issue. White/Gray smoke is more in line with unburned fuel on a diesel. A blue tint is more likely oil. Have you checked your oil level to see if you are loosing any oil?
Granted this his is a commercial but explains smoke in a diesel rather well. Keep in mind our trucks are almost 20 years old they are going to smoke more than anything new on the road today. Have you done a buzz test on your injectors to make sure they're all firing?
