The truck has a 7.3 powerstroke and when I start it up in the cold it smokes white really bad then it turnes into light blue and also it slightly smokes light blue at operating temp. I have outruled the injector o rings. Turbo o rings, piston rings and injector cups. Could it be the fuel pressure regulator?
