Never any white smoke before today- this morning used block heater and had some white smoke and now this afternoon with 58 degree outside temps getting lots of white smoke at start up and until warm. A whole lt! Checked coolant and seems a bit low. All numbers on my Edge Insight seem inline.

Whats going on?

Thanks.

 

Smell the smoke. Best way is to pull your hand in the smoke for a few seconds until it's wet then smell your hand. Coolant smell is likely EGR cooler, fuel smell may be injector issue. If it's a coolant smell you can pull EGR valve and check for coolant there. Parking with the front of the truck a little lower than the rear may help also.

Wide outside temperature fluctuations and high humidity can sometimes lead to a lot of condensation that will dry out as it warms up. Exhaust residue will be more like water with some soot in it, not much smell.

 

what Year??

Hows the FICM Voltage??

 

2005 and FICM right at 48.5 while driving. Now trying to figure out if its white or blueish white...
Billows out when starting and smokes good until its been running for at least 5 mins. Started it earlier when it was already warm and had same results. Seems to completely go away after about 5 mins. Have MBRB turbo back with gutted cats and doesn't sound like the same hair dryer effect it previously did if I recall correctly. But boost is fine and drives fine, just excessive smoke.

 

I also checked my DTS codes and there are none...

 

It's getting colder out in many parts of the countrywhich causes lots of morning dew so this would make sense. Except I think he said it happens even with a warm start?

 

Out of curiosity do you have CCV (crank case vent) to atmosphere?

 

Rusty mention to pull EGR I would try that

Also pull the Down pipe off the Back the turbo and see if its dumping oil in threw the turbo

 

Ugh. Just checked coolant reservoir and it is empty. Pulled EGR valve and it is sooty and only lightly gummy...

 

when did you check it last??

Pretty good chance time for EGR and OIL Coolers

 

if you pulled your EGR and it's wet that means it's time to replace the cooler or delete the system.

 

Do you know what your oil and coolant temp spread at operating temp is by chance?

 

My EOT and ECT delta runs around 7-8 degrees consistently. I checked coolant reservoir yesterday and it was a good level. Drove about 25 miles last night. This morning checked and was empty. Only seems to billow smoke after starting and the for about 5+ mins...

 

If you can't tell if there is coolant in the intake you can park nose down and let it sit overnight. Pull the Egr valve the next morning and check for coolant.
With a delta of 7-8 I don't think it would be necessary to replace the oil cooler(some people have and some haven't and turned out fine) but you are almost other when you pull the intake manifold.

 

Ya looks like his EGR Cooler Sprung a Leak 05 was squre so

Have you checked ECT EOT at cold soak??
