i have an 2004.5 ram 2500 diesel with a 5.9 cummins 325 HP that has been rebuilt with new injectors and has about 17,000km on rebuild to date. i notice white smoke at startup especially if its cooler outside. is this normal? is it leakage or programming. i understand what causes white smoke just cant believe that new injectors leaking already.

 

How cold a start was it? Under some conditions, a little white smoke at cold startup is normal (but frowned upon by EPA).

Excessive injection advance is also very well known to cause white smoke. If you have any kind of programming done, return to stock timing and see if the issue persists.

Also, try cycling the intake heaters a second time-- see if that helps it go away. If so, it's likely that everything is OK.

temp was about +4 celcius. truck was not PLUGGED in either. i just cycled the key once like normal until intake light went out.truck has edge juice on level 1 (25hp low boost level 1 for no smoke)

 

Was it white smoke, or just steam vapour? Hate to ask the obvious stuff first. I know when it gets cool, my truck has steam/vapour coming from the pipe as well when its cold.

 

Probably not a problem with your truck.

 

was kinda colder out. could of been kinda steamish looking. went away after 45 seconds or so.

 

I had this for a while. Oddly enough it disappeared when I changed my fuel filter.

 

It also depends alot on what you had done on the rebuild? Did you change compression, etc???? Or did you just have it rebuilt to stock specs? If it is stock change the fuel filter and monitor your trucks idle very carefully.

 

nope better get your motor rebuilt again lol


just ribbin ya

 

lol i will change the fass filters this spring. i changed them 10,000 km ago (7 months ago)i cant see how fuel filters make white smoke?

 

It's normal when it's colder outside as long as it only lasts a couple minutes. It's gonna do this just like a car does when you start it first thing in the AM on a cold day.

 

I live in Sask, and mine does the same in the same weather. Just a puff of white smoke at start up.

 

Mine does it also. Completely normal.

 

When it's cold I get a tiny bit of white smoke until I get down the block, goes away within minutes. My injectors all tested fine at rebuild time last November.
