Hey guys, looking to buy at an early 99 F-250 (191k)that the owner claims puffs white smoke and runs a little rough for about half an hour until warms up. Owner also claims that truck will idle all day long, and white smoke and rough running doesnt come back until next morning when you start the truck. I am in NC, and this thing is in FL, so I would hate to go all the way down there to have it be something major. Is this a textbook injector problem??? I have been told that its injectors... am I on the right path??? With the miles on the truck, would you guys replace all the injectors, or just bad ones?? I dont have the time nor facility to do it myself, so what am I looking at shop wise to replace what is needed (per injector, etc?) Thanks for the help!!!

Ok, I talked to the owner more about this.... There is no rough running at all. It runs and idles fine with no misses, just white smoke for the 1st half hour of running. Its on 37 tires, and he said there must be some chip in it b/c it will smoke them upon takeoff. Maybe this will help some b/c I am lost... No check engine lights either.

Could it be a dirty injector from bad fuel?

My old motor(early 99) did that same thing. Problem is, it had a blown head gasket. Same thing he's describing. Might want to get a compression test done if that's possible. Or look for mixing between the fluids if you can get a look or have someone near there go take a look for you. Just something to think about. /ubbthreads/images/graemlins/crazy.gif

White smoke is the death bell tolling on these trucks.

Most trucks with white smoke have had a bunch of debris run through the intake, turbo, and engine...the turbo fins will look sandblasted, pitted, or missing.

An injector (nozzle stuck open, dribbling fuel into the cyl) can cause white smoke...but left unchecked, the dribbling fuel will do damage to the piston and rings...basically there will be a constant fire in the cylinder...not just on the power stroke.

I would not buy that truck without personally doing, or overseeing a compression test.

take care~
