Default Clean injectors -water or other?

I have a 93 that I have been experimenting on with alternative fuels. Anyway at this point my injectors are plugged up for the second time. I am thinking of running a gallon container with marvelmystery oil into the pump feed line and seeing if that wont clean things up.

I have already tried 2 cans of seafoam into a 1/2 tank of diesel and its not working. Any better ideas about cleaning them without pulling them would be great.

We have heard some interesting things about water vapor but am not aware how to implement. I appreciate your input about how to clean the injectors.

Sorry you going to end up pulling them...

As for alternate fuel usually turns out poorly... (ATF and WEO)


Reason being why the WEO and ATF have such issues now is the amount of ASH content in the oils they are way too high and the organic metal (ash) come out on the injector tip and piston tops. This is another reason I don't suggest this idea any longer. Today's ATF has friction modifiers and anti-scorching compound that prevent burning. Then todays engine oils have quite a bit of ash.

I have left injector tips in injector cleaner all night and cleaned them off the next morning with a rag soaked in the cleaner. Oddly enough, nothing was cleaned. That carbon gets on there from combustion which bakes it on at over 1000F, I really doubt some paint thinner (injector cleaner, from all I can tell) is gonna thin out baked on carbon.

Found the video I made of it when I did it. My injectors might look pretty clean compared to what Mike posted a few posts up but I take them out and clean them all the time so they don't really get too dirty. I also didn't clean them at all before I threw them in, meaning the black stuff on the towel was all the loose deposits, like whats in your exhaust.

That video is so correct...:cool:

I've tried soaking my injectors as well and had no effect. So any product claiming to clean injectors I hardly doubt it will. Like I used Coleman Fuel which happpens to be just about straight Naptha which is the main ingredient to most all injector cleaners on the market.

The only way to clean a injector is to physically remove it and using a polishing compound like Mother's Aluminum polish or like I did with a used Scotchbrite pad and physically remove the carbon build up from the tips of the injectors. If you use a compound like Mother's make sure to blow all the compound out of the nozzle holes. Don't use sandpaper or anything like it!

While the injector is apart look at all parts for wear and fitting issues. Like if you insert the pintle back in the nozzle and its sticky double check the pintle for wear or being bent by rolling and a piece of mirror or glass. Any parts that are damaged replace them or just replace the injector.

Always work with only 1 injector at a time! Never disassemble more than one injector or mix and match parts. Every injector is tune to there particular parts so if you mix and match your for sure lose your pop pressure calibration.

If changing nozzles or part of a injector you should always re-pop test the injectors again and verify they are working correctly.

I tried and tried and the mothers will NOT scratch that tip. It is just hard enough to be abrasive to the carbon but not that tool steel or whatever it is. But yes you must get it all out, when you are spinning the tip the stuff goes into the tiny holes so filling it with penetrating oil and blowing it out with an air hose several times until you can see that each hole is blowing perfectly.

Dang... Where is the thank you button!?!?

That is the other thing ISX remember for me is the injector tip is rather on the hard side thats why I figures a used (soften) scotchbrite pad was safe because it will remove the carbon but will not scratch the tip up. But with either method you use make sure to clear the holes with solvent and air. :cool:

Well if you really want to get down to it, that tip is Latrobe LSS L6 Tool Steel. So if anyone wants to look that up..they will find it's really tough stuff.
