Still Smoking!!!

well for both of you it could be that the air fuel mix is wrong and its shooting fuel into the motor. what color is the smoke after the motor warms up?

Ridnlow... how much has it been running since rebuild ??

It can take up to 14 days of normal use of the truck if your mufflers is filled with old oil, it did with mine !!

ive got a FI b2600 i just bought and it smokes blue quite a bit on start up then when its warm its good but its brutal on start up for like 3 mins i need to fix this its embarassing hahahaha is it probably the valve stem seals too ???

Blue smoke means oil in the combustion chamber. Two options, valve seals or rings. Possibly a little of both. Oh could also be plugged oil return passages causing pooling after siting. Which would thin out as heated and allow flow after engine warms up.
