have been working on my 5 ton. i found the fuel line that was bad and replaced it ,so no more sucking air,, i got some of that dye that you put in the fuel and found 2 injectors that are leaking fuel ,now how do i go about getting them out?? do i have to take the head off ??? i have been told that i can take the adjusting screw loose and move the push rod to one side ,rotate the rocker arm out of the way,,thought i had better ask you all before i try,,thanks for the help..
