Color is black, blue/grey, and white respectively; the color of the smoke helps in the diagnosis. The older the engine the more those three start to intermix, which can make it hard to pinpoint what to try to fix first. You should have a compression and leak down test done by a shop so that you can tell how healthy the rings pistons and valves are. If they are reasonably close to being right then you are probably looking at dirty injectors or overfueling, assuming the smoke is black-ish.
If the smoke is blue or grey then you are consuming engine oil. That's worse as it means the rings or valve guides are worn out. Since you say it happens more at low speed that would be my first suspicion. Consider too that the thing probably hasn't been run all that much, so it may settle down some with more driving.
Off road, you just put the truck in low low, and let it walk over stuff, keeping your foot off the loud pedal. The Series diesels really benefit from at least a rear locking diff, as they tend to have enough torque but the tires break loose.
I suffered for ten years with one of those engines. I even rebuilt it, and it still was the slowest thing. Now running a 200tdi. All I can say is wow.
I think that you are right about the oil consumption. The smoke does tend to be bluish and grey. I don't know if I have the funds for a compression test just yet ( Next semesters tuition is due soon) but if I can, I will try and find a shop. I also know that you are right in saying that it has just sat for a while, I was told by the previous owner that it was.
I definitely want to get the 200tdi conversion, but again, currency is important for the exchange of goods and services.
I am gonna go pop off a quick photo for you guys, but based on what I have read, and what I was told, and the research I have done, it is a 2.25 Series IIA diesel engine.
