It seems like a lot of 6.9 & 7.3 have problems with white smoke i have read a lot about the white smoke on different forms. I'm new on this site so if I'm doing this wrong please let me know. I have a 84 f250 with 6.9l rebuilt 30 over have been working on it for 2 years (been taking my time) got it back fired it up, ran nice and smooth for about 15 minutes and started smoking and missing, leave overnight, start next day no glow needed, starts clean and smooth for 2 minutes and back to white smoke. Any thoughts would be appreciated. Thanks
