Its 7.3 a diesel and its putting out blue smoke when running
will a injector code 1273 make a 7.3 diesel smoke when running? on 2000 Ford F-250 Super Duty
If the injector has a bad spray pattern they can crack the piston. In this case oil can get to the combastion chamber and te crankcase gas pressure get high. Can you check these or you allready did?
