    What is white smoke?

    Give this a read.  Points to a few things that might be relevant.

    Not sure if heaters is the issue, still smokes at idle after a run of 6-8 hours.

    How about some wolverine oil pan heaters?  My 6CTA’s smoke pretty good on a cold startup but the heaters help reduce the smoke quite a bit.  White smoke is unburned fuel droplets in the exhaust.  Some good heat should help.
