Blueish white smoke when accelerating
This happened to me- lots of blue/white smoke up a steep long hill- and the cause seemed to have been air intrusion in the fuel lines/around the fuel heater. Got new lines and gasket around the fuel heater and no more smoke.... well, no more blue/white smoke at least :-)- J Mark

7.3 IDI slow to start after fuel line replacement

Had a local mechanic replace the fuel lines recently due to cracking, and since then it's had a hard time starting when cold. It'll cough a bit of smoke right away, like it...- J Mark
