2012 6.7 deleted, 260k. I received a balance/contribution code for the #7 cylinder.
at first it seemed to run fine and I noticed no issues. After a couple days it ran rough at idle then the next day it developed a bad miss.
i removed the injector and found that the clamp bolt wasn’t very tight and the copper washer was missing and the injector itself was caked with carbon/soot about halfway up its length. Keep in mind the injectors are all about 1 year old as I replaced them all last winter when my HPFP went out. The other injector hold downs seem tight.
what could have been the cause of this? It certainly was right when I installed it and im assuming either the copper washer melted or turned into small particulates. What is the procedure here? Vacuum it out and proceed or remove the head and look for pieces?
I guess my next step is a compression test? I’m just baffled how this would happen? Seems to me maybe the injector came loose and the gases from the cylinder melted the washer? Any ideas?
I question the replacement in jectots on the market…you don’t know if your just getting cleaned and tested versions of what you took out.
many will say if the replacement is cleaned and tested and sold as “refurbished, remanufactured, blah blah blah” it’s got to be good.
but…wash off a used light bulb that still works and it will look new and still consume the rated watts…but…the remaining life on the filament will not change and burn out
hard to say who s dually sells new injectors do you don’t know how old the injectors you put in really were. Even ford sells remans..the stuff they remove from failed trucks that get turned in as part of the core charge.
