Another white smoke story

[jhmason21]

I've looked at several threads on white smoke, no one has described my problem. So it started today, drove 45 minutes north of Nashville to a wedding. truck sat about 2.5 hours. Went to leave started it up, a whiteish smoke was exiting the tail pipe, not like cold in winter white haze, a good deal. My ECT and EOT were already reading above 170*, as it's 90* down here. So went to back out of the parking spot, still there. After I got onto the street I acceled briskly, never over 2500RPMs, clears up until I get out of it, then a blip of white smoke happens. Clears up completely after 5-10 minutes. I know white smoke = coolant eventually HG.

So is it EGR cooler? or FICM going bad? I'll check my FICM voltage tomorrow, didn't learn it could be bad FICM til I read up on it. I'll also try to get a video tomorrow if it does the same.

Thanks guys

Get out and grab a whiff of the smoke.
If it is sweet smelling, its coolant and your EGR cooler has failed and your oil cooler is plugged.

Yea I will do the smell test tomorrow morning. I also flushed with restore and restore+ and replaced with an ELC. ECT and EOT are always between 4-8*

Alright guys I can't figure it out. I started it cold this morning, nothing. Drove it for 30 minutes until it was good and hot, never smoked. Let it sit for a couple of hours, started again, no smoke. Coolant level looks ok, oil looks clean. FICM voltage was 48. Should I take it in for a look over and compression test? Will I get a DTC for a bad EGR cooler?

Injector(s)

Check out this video. This was my white smoke problem that I swore was a bad EGR/headgasket. Ended up being 2 bad injectors. How many miles on truck? What kind of oil do you use? Do you have a bypass filter for oil?

[jhmason21]

154,xxx just changed the oil 500 miles ago to Rotella T6 5w40, and no bypass filter. That's what mine is doing. Especially that puff of smoke after you bump the throttle. Did you try RevX? How long did you let the problem go before fixing?

[taskforcefreddy]

I let it go a little while because I knew it wasn't HG's or EGR as there was no puking or loss of coolant. Plus, I was in the middle of moving from AZ to el paso tx and really couldn't shut it down for a couple bad injectors. Finally took it in about 1500 miles later and got the injectors replaced under warranty. Once injectors get to that level, they usually need replacement. Rev-X can work but is more effective for earlier symptoms.

After this, I ended up getting a bypass filter and am now using T6 every 3,000. Really want this truck to last 300,000+ and keeping the oil and coolant clean is the best way to start.

Did it smoke everyday once it started? I guess I'll go ahead a take it in, thanks man for your help, makes me feel better it's probably not a HG.

And Thanks for your service, your video is bad fuugin asss!!

And what bypass filter are you using?
