White smoke from exhaust

YOUR MECHANIC MUST HAVE GONE WAY UP NORTH CAUSE I'M IN CENTRAL WI AND AFTER TODAY WE HAVE VERY LITTLE SNOW WE DIDN'T HAVE MUCH BEFORE. SNOWMOBILE TRAILS NEVER OPENED HERE.

 

I have a 09 387Pete with a Cummins 525 in it.it started blowing white smoke when I would crank it a couple weeks ago just had new injectors turbo and overhead done does anybody no what could cause the white smoke

 

how cold was it could have just been steam/condensation.

 

Hi, I know this is an old thread, but did you happen to ever figure out what was causing this problem? I'm currently have the exact same problem and have already repaired all of the exact same things you listed. I'm at my wits end, any input would be greatly appreciated!

 

I have an International Prostar with a Maxxforce. The exhaust temp light will come on for a few while idleing. It just started nlowing white smoke while initial accelerstion then it stops.

 

I have a 09 prostar with cummins ISX. anyone know what that color of smoke from exhaust indicates.. also it burns oil pretty bad


thank you.

 

I have this same issue. I have a 2015 Cummins isx and it blows white smoke out of the top on cold mornings and I also burn oil and add a gallon every 5000-7000 miles. I have a bypass filter in the crankcase filter and that’s helped reduce high crankcase pressure. You could have some blow by issues. I also have some milky white substance on the underneath of my oil cap. Check to see if you have any buildup there or the crankcase filter. If so you likely have a coolant leak into the engine. The oil burning is from the pistons needing to be redone. I’m am going to take mine to the shop in about 4-8 weeks to have engine redone(inframe) and checked for egr leak or head gasket leak to solve precipitation buildup and white smoke.

 

All of my trucks experienced white at 10 degrees or colder. but particularly between 5 below and 10 above.

This was long before today's emissions.
