Ok I have a 6.0 and I am almost for sure I know what the probelm is but I want a second opion first. The truck is using coolant and white smokes bad it also builds pressure in the system just after 10 min of running in 20 degree weather. Is this the sign of a bad egr cooler? I wouldnt think it would be a floated head but maybe a head gasket. Any insight on my issuse?
Thanks
