I bought a 7.3 turbo deisel and it smoked white a little when i got it. i was told by lots of people it was my injectors. so i changed them. And also my glow plugs and map sensor. But it still smokes. Some one please help me!!!!

 

Got to stop throwing money at it... White smoke could be many things...

Have someone with a good nose drive behind you when its doing it. See if it smells of fuel or coolant.

I would guess its a turbo issue, the o rings are more then likely leaking oil past and into the exhaust. Most times this happens when under load. If you leave it idling for a long time see if it does it worse for a bit.

 

What he said ^^^^

 

I took it to 3 mechanics all of them said injectors. And it smells like fuel. its getting to much. and letting it sit al a idle it just sits there the same. I had one mechanic say it might be my harness.

 

Did any of them hook it up to a scanner and look at anything?

If not then go find a real diesel shop that knows what they are doing.
