White smoke is fuel not being burned properly according to the Exxon website. Black smoke is when the diesel is "over-fueled". So I would say you might have a timing problem, as another poster already said.

fixed my timing finally and now she runs like aclock!:jump::jump::jump:

Good deal!:tu:

how did you fix your timeing because mine does the same thingg???
