Q -  why would a 6.4 powerstroke put out white smoke thank u Carlos

A - Hi Carlos,

Most generally when a 6.4 Powerstroke is putting out white smoke there is a problem with the egr system. Either a cooler is leaking and coolant is getting into the intake or the egr valve is stuck open. Other possible causes could be a problem injector or leaking seals on the turbo but they usually produce smoke that is more grey or blue. I would start with the egr coolers or see if you are losing coolant.
