i have a 94 f250 7.3 idi turbo vin k zf5 5 speed 4x4. truck ran good for a while then the garret turbo went out in it. so i pulled it off and put a new one in. truck sat for a couple months. got it started and it now heavy blueish smoke then goes to just a little blueish white smoke. while youre driving it down the road its more of a greyish black smoke. when idling on first start it kinda misses and a couple puffs of blue smoke come out. any ideas of what would cause this? thanks

 

sounds like the injectors are dirty put a quart of transmission fluid in the tank should maybe take care of it.
