Very interesting take on "rebuilt" injectors.. - Page 2 - PeachParts Mercedes-Benz Forum

I'm not selling them. I just copied the auction text to here so that the thread will still have meaning after the auction is gone from eBay.

ok. I just had 16 random injectors tested and put 5 'good' ones in my 116 sd. some of them had different numbers on them indeed. it runs and idles exactly thesame as before, when it had 5 completely bad injectors in it. (ran it on veg oil for the summer) I think the injector doesn't make too much a difference. maybe in MPG. as long as the engine gets the fuel, it's ok. the pressure will burn it all anyway. hooray to the precombustionchamber.

All the injector in these needs to do is pop at the right pressure and shoot straight. The ball in the precombustion chamber does all the atomizing.

Wanna bet? If the fuel is not atomized, think it burns well?

Yeah...those qualities really shine through, don't they ?

Anyone who is presenting themselves as an authority, as indeed he is, needs to have someone else do the write up if they are admittedly sort on the English....to maintain the standards that they are trying to sell.

It has to be said, that he is trying very hard to put over his product as superior...no ?

Whether or not you can write eloquently or not is never a reflection on the quality or effort you put into manual work unless you are trying to sell your work on quality, as he is.

G'mornin' Guys,

I read and re-read the ad for those injectors.....in my humble opinion, there is a bunch of both good and bad info in that fella's writeup of his injectors.

Personally, I am a USCG Lisenced Marine Chief Engineer, Steam and Motor, Unlimited Horsepower.....but I have been retired for the past 10 years. A couple of years after my retirement, I took a job at a Fuel Injection, Test and Calibration Shop ( I was getting bored). This particular shop also rebuilt Turbochargers....therefore I have seen and operated all of the various testing equipment that that particular shop had. To include digital fuel injector popping equipment, and digital high speed balancers for the turbos.

I have never heard of the "sweet spot" that the injector's seller discusses. However I have lapped fuel injector nozzles and pintles with talcum powder, yup, talcum powder.....was also taught never ever to touch needles and guides, pintles, delivery valves, and plunger/barrel sets with my fingers, unless my fingers had a good coating of diesel fuel...as the oils in one's skin can actually etch the highly machined surfaces......was also taught never to put any of the mating surfaces, metal to metal fit, together with any form of oil, dry only, because even a molecule of oil will eventually cause a leak.....please note I am referring to non moving metal to metal surfaces that seal the injector or the injection pump.

As, I am a do-it-yourselfer, these days...and I have no popping bench, calibration equipment, special tools, and a very clean area in which to work. as well as easy access to special parts and shims. If / when I feel the need to overhaul my injectors or injection pump.....I will take it/them to a reputable "Injection Shop" for testing and necessary repairs/replacement of parts.

The buzz that the seller speaks of...is a true fact...however, I do not know if it applies to these specific injectors...one needs to look this data up on a computer with a Bosch CD ROM, or if they are before a certain year of manufacture....on an old fashioned micro-fiche....the pop, buzz is important.

The leakdown, is also important.....although it tends to manifest itself as a dribbling injection nozzle....and I suppose in theory, it could present itself as an out of calibration Injection Pump....but any leakage in pressure that would cause that, would probably be noticed as fuel running down the injection lines and engine.....leaving a nice fuel puddle under the car.

As far as applications go....I am not a MB expert....however, if a manufacturer of any German equipment puts a part number on an item, it will be the same part number across their entire equipment/automotive line. BUT, bear in mind, when dealing with Fuel Injector Nozzles.....you need to check the "Fuel Injector Assembly" part number......there may be cases where the injector body will have the same part number for different applications, but the injector nozzles will have different part numbers.....therefore the "assembly" will have a different part number.....

Fuel Injectors and Injection Pumps are assemblies of very specific parts, most of which are machined to very close tolerances....one could spend weeks in classes at the University level, just learning about what and why it works.....I personally would leave it to those who do injectors for a living!!! If a shop has a Bosch certification.....it will be good enough for my injectors.

If/when I need to do some work in this area, I will ask a couple of MB dealerships where they send their stuff for rebuild.....also will ask the local tractor and/or heavy equipment dealerships, where they send their injectors....a good Kenworth, Peterbuilt dealership would also be a good place to ask.......Caterpillar, if the shop that they use, is also Bosch Certified, but Caterpillar injection equipment bears little resemblance to Bosch stuff......

Enuff Said,
SB

Please don't correct my grammar or punctuation.....I never got a degree in any of the Arts or Humanities......and I am not typing a letter that is trying to convince my boss that I need a couple of hundred grand in injection repairs.....

This guy is a moron. I would not let somebody who can not write a complete sentence touch injectors for my car.

Hello I don’t know you but this is the moron that wrote the advertisement. As to who is the moron your deriving life’s pleasure from picking on peoples sentence structure on the internet have fun. I made more money before I was thirty than a smart felly like you will make in his whole life by 40 I learned money is worthless so how old are you anyhow
Hitman
I know you I bought a part from you off this site. Too bad the best I can say is it only took 4 months to get my money back I think they call that selling parts you don’t own, fraud in some states and your final curse filled email was quite eloquently written I guess.
To every one else my son who still is young and believes in maximizing the potential in every thing he does has reposted the advertisement here.

He has raised the price and he will get it but that isn’t all there is in life I learned this the hard way but in the end I just smile.
That’s a thirty day money back guarantee by the way
Thanks for the PR

you think anything inthere will NOT burn, at those pressures??

It's not about if it will burn or not, it's about how quickly it burns.

As you have taken time to promote your son here....would you mind explaining the difference in the Injector Bodies seen in the photo of the e-Bay sale......

Thanx,

Yow. Small world. I will happily proofread and edit stuff for you if you like before posting on ebay. Though the message was not worded politely it is still true. I'm dyslexic and looking at a wall of text like that makes my eyes want to crawl out the back of my head. It also diminishes the credibility of the person selling. It's like being the world's foremost expert on economics and then showing up for a speech in shorts and a tank top.

Anyway, I'd love to help and don't want anything in return.

Didn't Alan Greenspan do that once?

Oh, it will burn. No doubt about it. Whether it burns like it should is a whole different story. Atomized fuel burns at a certain rate. Fuel droplets burn at a totally different rate. Atomized fuel burns better than fuel droplets. Your engine was designed to burn fuel at a certain burn rate and what not. If not at that rate, well, you have stepped out of the specification range. Results may not be documented or desirable.

You guys sound like you know what you are doing when it comes to injectors, but IMHO your add is just too long. Try to rewrite it in an outline format or something to break it up a little. I look forward to one day rebuilding and pop testing my own injectors.
