Dirty injectors

[usramc]

Ive had a stuttering problem on my truck for a while even after changing the hpop, uvch's, icp, ipr, fuel pump, fuel bowl orings and lines. Finally decided to pull the injectors and change the orings and this is what i found.

Hmm...lots of people looking but no reply's. That cylinder has a oil leak (I know, you knew that). What cylinder is it? Engine oil and coolant smell free of diesel?

Ive only taken the passenger side injectors out yet but every cylinder looked like this. I think the orings were week then when i put a 17* hpop and tuner in it finished them off. Im changing all the orings and cleaning them up.

Check the turbo for an oil leak while your in there. Just to make sure that it's not coming from there also.

I got em all back in and fired up, just to find 2 injectors not firing! Dont know why i didnt check before I took them out. I've got a set of ad's on the way.

It's the frustrations in live that let you know that you're still living it. Are the injectors next to each other?

[usramc]

Nope, #4 & #7

Are you... all back together? Moving injectors would tell you straight out if the problem was the injector or the electrical.

Yeah, but honestly i dont want to go back through purging the cylinders and ive already got a set on the way. But if 4&7 still dont work with the new ones ill know for sure.
