Home Made Fuel Injector Cleaning Machine
About a year and half ago... contiguous with doing a complete GM 3.4L Engine Rebuild on my Son's 1994 Camaro... I realized I would eventually need a full set of Rochester Multech EFIs P/N 17103007 (17.7 PPH) for his car and after checking around on the price and availability of Re-Conditioned Sets done by one company or another via the $10,000 ASNU commercial machines... I thought.. I'm sick and tired of looking and finding only a handful of ways and means to get these expensive injectors cleaned properly. So I thought...WTF... why not design my very own, off-the-vehicle system as a "Home Made Electronic Fuel Injector Cleaning Machine"? And that... is just exactly... what I did!
For those interested in all the slings and arrows I had to dodge and problems to be overcome before finally coming up with the completed version of this device which I originally called, "My Frankenstein EFI Cleaning Project" but later... settled in on affectionately calling it"
"The FrankInjector Machine"
FWIW...You can read all of the background on its development here at www.60dgreev6.com, where I go by the nickname of"60dgrzbelow0" :
http://60degreev6.com/forum/f97/home...machine-t42889
For those just interested in seeing the hundreds of developmental images and many, many testing videos I used to memorialize this project, please visit my Photobucket site here:
http://s557.photobucket.com/albums/s...ADEEFICLEANER/
Now I realize that many V-8 Enthusiasts and Purists might be offended that this machine only is fitted to clean Six (6) EFIs at a time... but you must forgive me for not including the width on the device to accommodate the other two EFI positions. There is a practical reason why I had to design the machine this way, which you will discover when you investigate it from its birth as an idea to a fully functioning and practical machine. I enjoyed working on it and I hope others will like the design and perhaps attempt to follow suit and build their own. I have no patents or copyrights involved and everyone is free to pick and choose from this project whatever they need to build their own versions. I think my work will stand on its own merit and prove to others that this otherwise very expensive machine can really be built in anyone's garage...and really work! I make no profit from the use of this machine... other than keeping the ASNU folks from getting even one thin dime out of me for doing the EFI cleanings on sets of them...
....anytime I like! :>)
I will respond to any and all inquiries if you drop me a line at my email address of: at60dgrzbelow0@yahoo.com
Thanks!

I've recently stumbled over a surprising buster of the Urban Mechanical Myth that the Rochester Multec Fuel Injectors have fuel filter baskets that cannot be replaced, with the exception of The Big Boys who sport the cleaning of these things with the expensive ASNU machines and jobber access to these replaceable filters in quantity. When I came across this video, I realized that all that noise about them being impossible service was just pure bunk. And so it followed that I did some more research and located several dealers that have these EFI Filter basket Kits for sale on eBay and found them available anywhere from around $10.00 to $25.00 depending upon which company you make your purchase from. Here is the video...and pay special attention to the gummed up, munged condition of the filter basket when it finally gets pulled out of the inlet nose of that EFI...and this repair is so surprisingly basic and easy to accomplish, too:
http://www.youtube.com/watch?v=V2sD5...rom=PL&index=1
Here is an example of the eBay offering (with Part Number listed)...This Kit is for the need for a V-8 engine, but if you intend on ordering several sets...three packs will allow you to make a fourth for the V6 Engines.
http://cgi.ebay.com/ebaymotors/Roche...Q5fAccessories
Putting in these new filter baskets will give any set of injectors a fresh, new lease on life, better gas mileage and horsepower to boot! I've posted more data and some higher quality closeup images of the contents of the kit and the instructions for its use for your better perusal on my Photobucket...here:

Thank You, Gentlemen...
FWIW...
Most of us have more than one vehicle sitting in our driveways... I suspect that most of us do not have more than one F-Body vehicle, although my son followed in his Dad's footsteps and so we enjoy having two of them. The 1993 Z-28 that I own has a mere 62K miles on it and I baby that car as you can well imagine (at least mechanically, anyway :>)). But with the possible exception of some collectible cars that are Normally Aspirated.., and some that sport Throttle Body Injection... the Lion's Share of our other vehicles are invariably powered with Electronic Fuel Injection. And when you think about how infrequently we actually service and clean these interesting electromechanical devices... its a wonder that they don't clog up, break down and quit more often than they do. Nonetheless... with such a small tolerance of only 10 Microns for passing through fuel under high pressure, it makes sense that they all get dirty and sluggish over time... especially if the recommended service time is around 50 to 60K Miles. So if you wanted to do an OTV (Off The Vehicle) cleaning of any set of injectors... you can count on the vehicle being down for around three to five days on average. Again... keeping in mind that if you own two or three cars/SUVs or trucks... and wanted the freedom of doing this work on your own... then all of a sudden...the idea of building your own version of "The FrankInjector Machine" begins to sound a lot more reasonable. As for getting extra sets of injectors... When I finally got the machine up and running in its earliest design phases... I needed some injector sets that were completely FUBAR so as to thrash the capabilities of the device out in the WCS (Worst Case Scenarios) and so I lurked on eBay and bought a few sets of EFIs ...some for the GM 93-95 L-32 3.4L V-6 Camaro-Firebird cars... and on average... they ran about $15.00-$35.00 for a complete set here and there and most of the time...the Sellers threw in the stock Fuel Rails, to boot!. And within short order of the cleaning cycles and care I have memorialized for everyone to check out here...
http://s557.photobucket.com/albums/s...ADEEFICLEANER/
...the majority of these injectors would prove to be very serviceable and passed muster for their amperage checks, spray patterns, and final flow match tests. With the advent of having several sets to pick and choose from... making up a set of balanced, squeeky clean EFIs was very easy to do...because you can SEE them performing on the machine and judge for yourself. With this machine and just a few hours away from what one might spend or waist nodding off while online... you can take a gummed up...'Eff'ed up set of EFIs and return them to completely better performance. As a project... it was a challenge to overcome some of the engineering problems. But frankly, since I built three completely unique versions over time... I spent a bit more money and time head-banging through some bad ideas and designs to get to the one that worked the best. But now that all the heavy lifting has been done... there is no reason that anyone with average mechanical skills (like my own) could not gradually accumulate all the required parts and pieces over time... and slowly...and surely...make their own machines right in their own garages. I simply cannot convey how much enjoyment I got out of seeing this damned thing finally work... knowing that there were only four other distasteful or inefficient and uncertain options to choose from in order to even remotely clean up a decent set of fuel injectors:
(1) Pour some EFI cleaner into the gas tank and hope for the best. (I get a kick out of this one... its a bit like taking an Aspirin and an Omega-3 pill in order to clean out the clogged arteries in a human being!)
(2) Send them off to one of the myriad ASNU EFI cleaning companies... and wait for another re-conditioned set to arrive...and of course...PAY them to do the work that averages anywhere from $100 to $300 depending upon what kind of injectors are involved.
(3) Buy a set of "BeeNIB" (Brand New In the Box) OEM EFIs.
(4) Pay a shop to Pressure Clean the EFIS on the car, engine running, etc.
The very idea that these options were all that was available to me is what started this whole thing! And now that it is done... I like the peace of mind that the machine is so flexible and lets me do the cleanings of other kinds of injectors as well. If you tunnel through the various video posts. I think there is one where I demo the cleaning of an Accel 19PPH EFI from a Ford Mustang... just to prove that it can be done just as easily.
Anyhow... I'm off the Soap Box now... but I just wanted to encourage anyone thinking about tackling this build to pace themselves, get the parts and pieces together needed over time and then have as much fun as I did in creating their own "Frankenstein" EFI Cleaning Machine! Who knows...maybe there is someone out there who can build the damned thing to work better and for less money, too. :>)

There have been some fairly exciting new developments concerning the creation of "The FrankInjector Machine" in the past several weeks that might be of interest to anyone in general concerned with very effective method of cleaning their EFIs in an Off The Vehicle setting. For the last few months, while proving out and finalizing my final design and build of this machine... I have been imploring the "lurkers" among the nearly ten thousand visitors/visits to this thread to get involved and just throw their hats in the ring concerning the development of a proper electronic EFI actuating device that would make this machine a completely self-contained and fully functioning apparatus.
You can look over the latter pages of this original post and will find that a design engineer named OLLOPA "Rick" (who I now call TRON...because "He Fights for The Users"...) has volunteered his time and expertise in designing and making what he calls "AN ELECTRONIC EFI DRIVER" that would be a healthy replacement for the dual OTC devices I have been using all along...but which are not exactly what you would call a "Fire and Forget" means of actuating "Frank" during all the various Pressure Cleaning and Flow Balance cycles. If you are curious to see what he has in mind... please see the latter pages of this now epic post (say...pages 21-25, etc.) and you'll find the text and images of what he is working on. If anybody has additional ideas in parallel with what is happening...please feel free to contribute your thoughts and suggestions there!
I think the V-8 enthusiasts here will also appreciate that in his efforts to build his own version of "The FrankInjector Machine"... TRON's images at this link show that he has included positions on the EFI "RiXInjector Rail" for all eight (8) EFIS!

Okay Folks... This is GREAT NEWS...!!!
Here is another engineering-type free thinker who really has completely solved all of the problems with his own Home Made EFI Cleaning Machine. This fellow...who goes by the nickname "marks" on YouTube deserves high praise... Check out the last entry and updated post I made on this subject here for all the information!

Okay... this fellow who calls himself "marks" on YouTube has a series of three videos that demonstrate his efforts to RNCNR (Remove and Clean and Replace) a set of four EFIs on his wife's Ford Escort...but the machine he has made to do this is pure brilliance and he has managed to solve all of the problems anyone might encounter with managing a closed, filtered cleaning solution system and the electronic variable controls needed to make it work. I'm sure that it could be scaled up to handle a full set of (8) Eight EFIs...
Take a look at these YouTube Videos and you'll see what I mean!

Re: Home Made Fuel Injector Cleaning Machine
Happy Holidays to All Who Dwell @ www.camaroz28.com
I just wanted to let everyone know that I have completely re-designed "The FrankInjector Machine" to accommodate not only Rochester Multec I Electronic Fuel Injectors...but now the cleaning fluid service rail involved is a modified one from the GM Vortec 4.2L In-line V6 Engine and supports the cleaning on the Ac-Delco Mutlec II EFIs as well!. I have noticed an incredible rise in the the number of hits on this issue (almost 26,000 to date) and I suspect that the economy as well as just general interest in seeing a real working off-the-vehicle EFI cleaning machine that we can all build ...actually work is what is driving this attention. Tons of constructive forum input as well as the "HowTo" Videos and Digital Images can be found here... (Enjoy!)
