blue smoke on start up overnight

[crushercannon1]

hi i have a 95 obs 7.3 210,000 when it sits overnight and when i start it in the morning it puffs out blue smoke untill it completly warms up also seems to have lower power and i have noticed that the injectors seem louder than normal all the time. Just need a little advise please.

Couple of things possible. Most common would be turbo seals, or valve seals. Check endplay on turbo shaft, and could also be the cause of you loss of power.

or colder weather causing incomplete combustion.. if it's not misfiring, who cares?
