Injector cleaning question

["C"bomb]

Checked out mopars video on cleaning injectors and had one question, he did not say anything about having to have the injectors pop tested after cleaning so I'm doubting they need to but I thought I'd ask before taking mine apart. Thanks for your input guys!

As long as you don't swap parts around between them the pop pressure shouldn't be affected by the cleaning.

What is the cleaning solution used in the video? Can you recommend any solutions that you would consider safe and effective to clean the injectors with.Thanks

I find it funny that everytime I am planning, or looking for something 9 out of 10 times someone already has a thread started! :cool:I think I remember him saying Colman Fuel in the vidoe as he is pouring it into the ash tray. What kind of Colman fuel though, I dont know.

The fluid (whatever it may be) is only to wash the loose contaminents off. Both Mike and I have tried several things and we can't get anything to eat away at carbon no matter what. According to scientists, the fluid has to move and will help clean away the carbon. Meaning it works while the truck is running. Whether or not this actually DOES work though is open to debate. In Mike's vid, it is the scotch pad that does all the cleaning, the fluid is just to wash the bits of scotch pad out of the injector since it has to be PERFECTLY clean before reassembly. Meaning, you can basically use anything that won't explicitly attack the steel of the injector, so don't use sulphuric acid.. I have used penetrating oil, WD40, uhh and everything else under the sun that has some sort of lubricating property and comes in an aerosol can. I want to be able to blast the debris out rather than just let it soak in it, therefore I always opt for pressurized cans of something. I opt for something with lube because it's an injector that relys on the lube of the fuel much like injection pumps so I stray far away from something that leaves it dry like brake cleaner. So my #1 choice is PB Blaster.. It's very thin and is "oil" so lubes nice as well. I spray and blow everything out with an air hose multiple times and then spray it and reassemble so that the oil is still coated on everything so that everything is nice and happy. BTW, the injector parts are made of very hard steel and hardly anything will touch it besides sandpaper. The carbon deposits are much easier to get off so don't worry about scratching the injector with a scotch pad because I don't think it will happen. I mean it's tooling steel....like what drill bits are made of, maybe even harder than those.

Injector cleaner "might" help in keeping the nozzle hole clean but it doesn't do much for taking the coked up diesel off the pintle needle.

I've had many many sets of tractor injectors sonic cleaned over the years.. the pump shop does it, and I have them set the pop @ same time. For the few extra bucks, why not? I ususally have the pump in too for either a rebuild or testing.Anyone want to take a stab at what process is used to put those tiny holes in the tips?? That has to be some impressive machine!

I believe it is EDM process. Electrical Discharge Machinin

What kind of interval do you suggest cleaning injectors? Would I see any performance improvement at 162,000 miles?

The shop I used to work at, we used a UltraSonic Cleaner (Just like the ones you can use for jewerly or guns), 99% of the time everything came off good as new, and we always pop tested afterwards. You can change pop off just tighten them differently or mixing up bodies. I have a pop tester but it's for older stuff won't go over 3000 psi.

I use either Mineral Spirits (paint thinner) or naptha (coleman fuel). I've been know to mix both together for cleaning. As for doing injectors I do then one at a time to prevent mixing of part and so the pop pressure isn't altered.
