blowing blue

[lil smudge]

I have recently had problems with my 2004 F350 blowing blue smoke!
It does it when I first get going, when I'm going up hills and when I'm at 1500 -2000 rpms, after that it settles down and cleans up.
I cleaned my egr valve and used many diesel additives and nothings worked.
Just looking for answers.
Thanks!

Does it smell like oil or diesel if it is blue smoke so the egr valve was dry not low on coolant how is the idle when you first start.

Had a problem similar to yours on my 06 a couple of years ago and it was the turbo. It was letting oil by the seals inside the turbo and causing it to blow blue smoke. They have a technical name for it, but I can't remember what it was. Took it to the dealership twice. They replaced egr valve first, to no avail, so I did the "ask a mechanic" thing online and a Ford tech on there correctly diagnosed my problem. Took it back to the dealership and told them I talked to someone who had this same problem and gave him the name for it and they wound up replacing my turbo, fixed the problem! Anyway, you may have something totally different going on, just thought I would let you know what happened to me and how it was fixed. Good luck!

the idle is fine like even when its cold it doesnt give me problems isnt hard to start as for the smell i couldnt tell you cuz it only starts when your moveing

the other day i started the truck and went to get some fishing stuff from the garage and it was blowing blue and it smelled like diesel

i would test ficm voltage just to be safe. as far as testing the turbo, you can pull the down pipe and look for evidence of oil burning in the exhaust.

Ok what would a good voltage be for a good ficm like what should I be getting

[lil smudge]

so i tested the ficm and got 48.5 volts at running and 48 with the key in the ignition so poped the down tube off and there was a lil puddle in the exhaust of what i assume is oil so thanks for all the advise i guess now ill replace the turbo thanks again

I had the same problem as tmanscrew. An easy way to see if the bushings are bad in the turbo is to take the inlet host off and see if you can move the shaft any side to side. It should have nearly no play at all. Mine had quite a bit so I replaced the bushings and rebuilt the turbo, no more smoke for me!

What about a blueish to gray smoke about a second or two after ignition? I have noticed that mine will let a lil puff go only after I start the truck but clears right up after the initial puff. Truck doesn't blow any smoke after that. No oil smell but I do get a whiff of diesel now and again when its cold (which I have smelled on all diesels I have driven, especially when its cold out). Is this normal?
