I have a 2003 Chevy 3500 with 135,000 miles on it. Noticed the other day that there is a white haze from the exhaust at an idle. Truck runs fine when driving i just noticed the smoke when its idleing. The smoke seems to go away once your driving it thats what has me stumped on it. I think its a leaking injector but im not positive on it because theres no codes being thrown in the computer. Any information is appreciated thanks guys.

 

whats the temperature on these days? if its cold i wouldnt worry too much as it should clear up especially while driving.

 

Yeah it smokes all the time wheather it is warm or cold. We have had some mixed wheather lately warm and cold days. The smoke is due to something wrong I mean if you have to stand in it long enough to hook a trailer it actually burns your eyes.

 

i would say possidly an injector problem...some sort of fuel system prob

 

Yeah thats what I was figuring. Im figuring its an oring leaking or something. But like I said it runs fine just smokes at idle. Thanks though I appreciate it.

 

have somebody run an injector balance rate test on it....it will show a leaking injector

 

Ok sounds good thanks.

 

Does it show any signs of coolant loss?i have an 05 3500 that was doin the same thing and i have the heads off now and im takin them to get magna fluxed prob monday cuz there is no sign of anything leakin.

 

No there is no coolant loss whatsoever. I thought heads at first to but there isnt any coolant loss on it.
