I have a 2002 2500 5.9 that when started on a cold morning blows white smoke for a min then stops. When I stop some Where and get back in and start up it puffs white for a second. No loss of power no CLE no soft codes. Not sure of fuel pressure. I know I need a gauge. My question is is this somwthin I need to worry about or no? I just started seeing it the last few days. But the temp has been colder the last few days.  Thanks for any and all help! 

Alright thanks y'all! I am going to keep an eye on things and see if it smokes again anytime soon.   Bout a quart per tank sound right for the 2 stroke oil?  I appreciate all of the help! 

Since you’ve haven’t added before just wait until your next full tank and then depending on how many gallons your tank is, add that many ounces. Then every fill up after that add 1oz per 1g.

Got ya! Thank you. I'll do anything to add to the life of the truck. 

Here is an article about it.

One oz per gallon is the desired mix but dont worry if you put to much or dont have enough at a fill up. Any is better than none. Just try and keep it close. TCW3 is a must as mentioned mention above by @notlimah. It is ashless.

I'll have my wife get me some on her way home.  Thank you so much!   Hopefully my white smoke wasn't anything to worry with and I can get a fuel pressure gauge asap

It is cheaper by the gallon if you dont mind measuring your self.

Naw I don't mind at all.  Thanks 

 Terrible pic but where the muffler ends it's rusted off and then u see the smoke. Like this till the grid heater stopped cycling. Normal? 

I'm curious do you have P0216 code? Remember some codes do NOT trip the CEL.

No sir. I don't have a cle on or any soft codes. 

Then the only thing that comes to mind is the injectors are getting wore out and pissy. How many miles on the truck?

187,000  stock injectors as far as I know.  So I take it the blue haze ain't normal for cold start then?

What’s the temperature when cold starting? As far as I know when it’s cold your going to get blue smoke. I get blue smoke when it’s 15 20 degrees and I have brand new injectors.

Injectors are most likely shot. Typically have to replace 100-150k miles.

 

Typically the blue haze could be either fuel that is not burning or like in my case it valve guide seal that are failing. But valve guide only let off a single puff of blue smoke and it smells like burning oil. Since you not talking about a burning oil smell I would have to stick to the injectors are worn out.

It was 32 with strong winds this mornin unknown wind chill.   Is it safe to drive or do I need to stop and get new injectors asap

You can drive it but you might get stranded when they go out somewhere away from home but if you drive the truck around local I’d go for it.

Safe to drive but the file economy will be lowered. 

 

In a nutshell how these engines work is your compressing air enough to create the heat. Then injecting fine atomized fuel into the heated air to make it go bang. So when the injectors wear out the injector pop pressure opens early. So stock is suppose to be at 4,500 PSI +/- 250 PSI. Now the injector is opening early the spray is not atomized good so there is a smoky haze because the heat isn't enough to make all the fuel burn completely. 

 

The most you might notice is a offbeat or miss idle when hot this is the injectors causing this. 

Alight thanks guys. I guess I'll try and baby it around town and work some ot and buy me a set. Rv275s is what y'll would recommend for good fuel mpg and reliability?  

I've had good luck with both RV275 Bosch injectors and Vulcan Performance +50 HP injectors. 

Awesome! Thanks guys I really appreciate the help!
