The smoke is a blue/grey. I replaced all return lines and have no seepage around any of them. What makes me think it is unburned diesel is the overwhelming smell. When I replaced the injectors with new manufacture Standeyne ones, two of them were carboned in pretty bad. I cleaned out the holes as good as I could. I suppose that could be a problem. I don't have one of those reamers that I have heard about here.
When the truck is plugged in the start up is immediate, and the initial idle is more smoth, but the smell and smoke are still there. I have a new glow plug harness to install (thing must be made of gold because of the price), and that may help. The old harness has some loose glow plug connectors, and one was completely burned off. I used bullet connectors to repair that connector.
The truck has an electric fuel pump. Wouldn't that help with any air problems? I am kind of stumped, but I will investigate all leads got here and thanks for any help rendered.
