I have a 2005 F250 6.o deisel and it blows so such white smoke it looks like it is on fire. Ford charged me for the so called upgrade that didn't fix it and they have now replaced the injectors and didn't fix it and now they are trying to tll me that I have to have a rebuilt engine in my my warranty covered truck...FORD SUCKS....never again will own a Ford product...They are covering up a recall..Does anyone else have this problem?
