I'd previously posted a thread about white smoke when I first got the truck, but that was when on the gas, with a warm engine. It was the turbo burning oil. got a new turbo.

A couple of months ago, I started noticing white smoke on startup, cold mornings, in the 30s, and only for a second or two.

fast forward a few months, the smoke seems to come out for a bit longer, and it seems that it happens at slightly warmer outside temps, 50-60ish, don't know about warmer, because we haven't had warmer yet.

I haven't noticed any after the engine has been running a while or when I get on the gas.

I did notice the other day that it was coming out for a good while, a few minutes, but it was in the mid 30s at the time.

I have not noticed any loss of coolant/water, I did not see anything suspicious in the last oil change (about 1500 miles ago) and I have not noticed a loss of oil..I think...granted, I may have put a bit too much oil in it last time..first oil change on this truck, may've over done it by about 1/2 quart, I've read that these trucks can take differant amounts truck to truck, with about a 1-1.5 qt variance.

I am mostly worried about having to pull and fix heads and head gaskets. Is there a way that I can check this in my driveway, see if there is something going wrong that I need to be concerned with?

I was on the gas this morning on an on-ramp, and it felt kind of jerky, like it was having power swings, but that could have been the road, or tire-slippage, as it was wet outside at the time too, and I did not think to floor it again today while I was on smooth road...certainly can't for the next couple of days due to freezing temps and ice storms starting tonight.

 

Sounds like glow plug controller is not letting the glow plugs get hot enough. Or glow plug or plugs going bad. Try this. If you have a block heater. Plug in overnight and see if you still have white smoke on startup. If not then you know it is a good possibility that it is in the glow plug or controller area.

 

Whats the smoke smell like???

 

I would watch the FICM voltage also (KOEO, cranking, 2000 rpm)

 

Need to know FICM volts KOEO, Crank and Cold Start.

Any idea what FICM strategy you have loaded?

I have no idea on the specifics of the tune, or even if it has the stock FICM or an aftermarket unit.

I will look for the articles detailing checking the FICM, it may be a couple weeks however till I get that accomplished.

As far as the smell, I have a deviated septum..so it is kind of hard for me to smell things, but it does not have an overly strong odor I think, that I should be able to pick up on. Slight diesel smell, as I would expect, but that is it. I've held my hand in the exhaust, and it does not seem to collect any moisture worth noticing.

If it matters, the exhaust is a turbo back 4" pipe with what looks to be a small muffler (but too large to be a cat, unless diesels use 18" long cats that are 6" around). And has one helluva whistling sound at idle..most people comment that it sounds like a jet trying to take off.

 

that's a straight pipe exhaust, and that can is just a resonator.
