white smoke/haze at idle
my truck is an 06 6.0 its studded and deleted with all the updates. about 2 mounths ago i noticed a white smokey haze at idle that would go away when i accelatered or if i just kept the rpms up. it wouldent happen all the time. the time when it would smoke the most is when the a/c was on high. when this would happen the truck would run fine, it wouldent miss or anything, you would neaver tell it was smoking unless u saw it. at first i thought it was the turbo seals so i pulled the down pipe to check for oily goo and found nothing. i hooked up my autoenginuity scanner to do a ballance test and found nothing.i also checked my ficm and it was steady at 52v (i have the high voltage one). i then by chance i looked over at my charging volatage and at idle with nothing on it would read 13.1v and then when i turned my a/c on it would dip down to 12.6 and stay their. could it really be that simple that the answer to my problems is just a bad alternator??? o and also the truck hasent lost a drop of oil or coolent.
