Can these injectors be cleaned at all ?

I am about to pull them out to check if i have aftermarket's in there

Should i take the little extra time and pull them all out to see if there's a dirty pair or something ?

 

I may be wrong, but I think you can add a little tranny fluid in with your diesel and clean em out. Again, I'm not too sure on that, but I know that's what I've heard them old truckers talk about

 

I'd run a bottle of Power Service through it and some 2 Stroke Oil.

 

So there is nothing i can do when i pull em out ?

Is there any thing i need to be extra careful of while removing them ?

And how much 2-stoke oil per how much fuel ?

 

You can and should take them to a local injection shop and have them cleaned and popped tested. They use a sonic cleaner and having them pop tested may just save your engine in the long run. My local shop here will do this for most of free but I don't know if that's standard or not.

For just dropin em in somethin I like Seafoam myself. That stuff cleans anything.

 

Local shop want's $40 PER injector,

i don't have that kind of cash

 

We use an ultrasonic cleaner. They get cleaner than clean.

Noob question,

Do i really have to pull my damned rocker to get at the injector ? I just had them all adjusted by cummins'.. and i don't have a set of feeler gauges

 

On a 24v truck nothing needs to come off. Pull the conector tube and put a valve cover bolt in the top of the injector and yank. I've got a bunch of miller Injector pullers if anyone needs one. $30.00 a peice.

As far as things to watch out for? DONT DROP THEM!!! dont try and pry on anything unless your snapping the CT out. Tranny fluid works fine in the fuel tank, Just dont use a gas & diesel fuel treatment and you'll be fine. For the most part these injectors are service free, You should need to take them out for a clean. Make sure you put your correct copper washers back in and DONT get them mixed up. It rarely causes problems but if one's already compressed to the injector bore in that cylinder it can change your spray pattern and cause some minor problems. Nothing to worry about on an injector below the 150hp range.

If I can be of assistance feel free to call!

 

run some sea foam threw the diesel that cleans them good
