NOTE This service letter does not need to be performed if Injector jam nuts have already been torqued to the higher spec during routine valve lash/unit injector adjustment as described in Service Magazine article SEPD0581(2001/06/04).
Remove the valve covers.
Place a flat head screwdriver in the injector adjusting screw and see if it will turn.
If the screw turns then the unit injector needs to be adjusted.(See step 5)
If the screw will NOT turn, mark a line across the screw, nut, and injector arm
