White smoke on startup

[Rmartin-97]

I noticed my truck white smoked twice now when I start it the only codes or anything I've noticed is check air filter light could that cause the white smoke? Or should I run a contribution test on my injectors or something like that?

Could be moisture build up in the innercooler.

Rivets are the new duct tape.

It clears up within 30 sec or less it's weird.

Yup most likely is it with the moisture. I put my no limit and cac pipe on last week and there was moisture in the cac pipe. I got white smoke on startup as well when cold

Are you talking it only does it first thing in the morning after a cold night? Or like when you drive to work and you get off work for lunch it will do it again after the motor has sat and cooled down but not cold?

Only when you drive it let it cool down for a few them restart it. It does nothing when you start it in thee morning.

No it was just studded last week.

Could be some moisture(water) in the bottom of the intercooler maybe? Common for 6.4s to get water built up in intercooler

Both there is nothing left but the moisture in the cooler that I originally said.

I would think it would be fuel from it not doing it after sitting all night

Condensation or an injector starting to go out. I have one bad injector right now that will do that every now and then.

Have you smelled it?

 

[BigBluediesel08]

Mine also started doing it after getting studded..it only does it when it sits all night or a couple of hours. Doesn't smell like raw fuel.

It just smells like regular exhaust.
