Do you drive it much? Does it ever get a workout(10Klbs in the bed)?

If not, throw as much weight as you can find in the bed, hook up a(HEAVY) trailer and drive it for 2-3 hours. Report back afterward.

Good advice. Put three yards of sand in the back and drive it around. It is a heavy duty tactical truck meant to get it done or fail trying, or another explanation ...............

Chris (gimpyrobb) is right. Blue smoke is engine oil and if you haven't driven your truck hard lately it can cause the rings and cylinder liner to take a "glaze" on them. Piston rings have a wedge gap that faces the top of the cylinder. When operating, the pressure of compression goes into the gap forcing the rings against the bore thus helping them keep the seal against the compressed air/combustion forces. If your not working the engine hard this pressure is lessened and eventually causes the glazing and then oil will start leaking into the combustion chamber and getting burned causing the blue smoke.
So take it out and run the crap out of it !

I think that's happening to my Deuce now. Had to move her from one spot to another in the same parking area almost every day for the last week or so. Noticed more smoke than usual when I started her up yesterday. Time to take her out, let her run a little and bring everything up to operating temperature.
