HI,

my name is Anthony and I’m looking for a little help with some questions. This Forum has been a Major benefit to me as I have been reading all sorts of post and answers about my similar truck.

- Cold Air Intake, 4" Exhaust Straight Piped. 90,000 Miles

It started about 3 weeks ago.... I first noticed a little Puff of Bluish white smoke after coming to a complete stop at a light and taking off. so I tried a couple of scenarios like 30MPH then let the truck just engine brake at idle and give it gas and no smoke, so it only seems to be doing so when I’m first taking off or at really low speeds and accelerate. I was told it could be coolant leaking into the exhaust and burning off, and that I wouldn’t notice it while I was actually driving at higher speeds because it was burning it off before I could see so.

Also in the morning when it’s cold and I first start the truck it smokes a clear condensation smoke, strong odor of diesel and once the engine is warmed up it doesn’t smoke any more, same goes for at idle, it doesn’t smoke at idle either, just when I give it the first initial gas to go..... ?????

IDK any answers or theories would be helpful as I am out of town and it seems to be getting a little worse as the weeks go by.. I Also Threw a code For EGR Circuit Low the other day.. would that have anything to do with the smoking issue

 

I havent experienced this problem so im not 100% sure my reply will be right. However I'm very familure with gas engines and blue/white smoke is a sure indication of coolant in the combustion chamber.

My recommendation is check your coolant if its below "low" chances are it is leaking. Next step pull the egr and check for wetness. Now would also be a good time to clean it too. It doesnt come out easy but with a little leverage it will come straight out. I got a crows foot pry bar just for the job

Good luck

 

Definitely clean the EGR valve, and test your FICM.

Welcome to DB

 

mine was doing that same thing and it was my turbo seals going bad just somthing else to check

 

Thanks for the suggestions, this is the same kind of answers ive been getting.. which pretty much leads me to having to take it to a shop where they can run some diagnostics. Im definetly not mechanically inclined to be pulling my truck apart and checking stuff. once i got it off i wouldnt know what to do with it anyway. So Im ASSUMING that the truck is still good to drive until I can get it in a shop?

 

Personally I wouldn't be too concerned, a injector might be getting weak or you might just need to run some cleaner through the fuel, it shouldn't keep you from running it, check the airfilter too, when they get clogged it will puff more then usual

 

there was a bulletin on turbo oil supply line .

 

Hey Guys I think i have located the Problem.... thanks to Yalls help... found oil in my exhaust and posted about that... the answer i got was my turbo is going to ****... i have another one, How hard is it to swap out and any advice on doing so....?

any help would be great.. thanks

 

Not hard at all. I could do one in probably 30 minutes. A first timer, plan on 2-3 hours. Basic hand tools.

Remove the entire intake up to the turbo. Remove the CAC pipe on the passenger side (metal intercooler tube that feeds from the turbo to the intercooler). Loosen the clamp on the downpipe and pop the downpipe off. Loosen the clamp on the up-pipe. Remove the turbo feed line (one bolt) and move it out of the way. Now on your 06, there are 3 bolts that hold the turbo to the pedistal. Two are in front and are horizontal to the ground. The third is in the back on the drivers side and is vertical. If you lay down on the passenger side of the engine and look behind the turbo you might be able to see it. The easiest way to get this bolt is find the exact height of extension socket that allows you to go over the top of the downpipe and down to the bolt. It will give you ample room to work the ratchet. This is the trickiest part. Once you find the right combo and length of extensions, it will be super easy and you'll see how you can cut a bunch of time off next time you take one out. You can also use this time to upgrade the turbo drain and turbo feed (I find the turbo drain line is far more important than the feed line myself, and it's also cheaper. So at a min, do the drain).To actually pull the turbo out, you'll need to sort of rotate it as you pull it out, it will come right you, you'll see. An extra set of hands will help too.

Updated oil drain: 6C3Z-9T515-A
Updated oil feed (for 05+ turbo): 3C3Z-9T516-A

When reinstalling the new turbo, rest the turbo into position, just start the mounting bolts but don't tighten them up yet. Tighten up the up-pipe connection FIRST. Then the downpipe. It is important to do these connections first since they are more rigid than any of the air side connections, and those V-band clamps will not pull the two pieces together. Once those are tight, then tighten up the turbo mount bolts, then put your CAC tube back on, and your intake. Do not forget the filter minder on the back side of the air filter, this is left off too commonly.

 

WOW! Thanks Man!! this site is a major Help... I will definetley be a memeber for life and will pass along the info i aquire along as well
