7.3 blows white smoke at 1900-2500 RPM and then clears up

[Colin7.3]

Quick question.

The truck belches a thick puff of white smoke if you rev it up real fast from an idle or a little bit above idle.

usually around 1900-2500 and then clears up.

any idea what be the cause??

Would be be possible to have a second person to smell it? Coolant level staying the same? How long was the truck running for?

I would guess coolant or fuel.

[Colin7.3]

it smells like fuel.

that was after its been running for a good hour.

coolant level is normal.

new injector o rings

Maybe an injector going.

my 05 did that once but it was my turbo leaking oil so it was across the board white "blue" whatever you can tell by smoke color... just an idea . maybe you could check if its at a certain level of boost..

just a thought..

unfourtubaly i dont have a boost guage so i cant tell you that one.

i got a friend coming down tomorrow to put the truck on the computer and see whats going on

i just installed my new down exhuast and the inside of the old downpipe was not wet and my turbo has zero play in it. just needs a new compressor wheel.



the truck still builds boost i can feel it kick in while im driving
