As long as it seems dependable, no issues but the blue smoke, I would drive it, A coupla decades ago blue smoke would have bothered me too much. I would have rebuilt it, now I would put off the expense.
So, think about what direction you are heading with the truck, and milk the dependable run, while saving for the master plan, rebuilt or upgrade.
Check oil, pay attention to the oil light [from the time you turn the key to on (light comes on for sure before you start the engine) until you turn the key off], temperature gage and fuel (duh). Check the oil and water (when cool) levels regularly.
Have you changed the fuel inline filter lately?
