Hey Guys-

I picked an 04 dodge cummins and have pulled the motor because it have a melted piston on #4 cylinder all the other cylinders show the 5 star pattern clean on the piston head. with no carbon showing in the star pattern. do I need to replace all the injectors or can i replace the tips. i've never had to replace or deal with a set of injectors. the oil was really high, i think from fuel entering from injectors. let me know your thoughts thanks.
