The brake booster feed line??? If that is the case, then it wouldn't even clean the intake runners.

 

but the question here still remains - is bottled "injector cleaner" (the "dump-it-in-and-fill-the-tank" kind ) harmless to rotaries? beneficial? or is there some type of professional cleaning that should be sought out in this type of dirty system situation?

 

id just send my injectors to RC Engineering and have them cleaned and flow tested.

 

ive already had my injectors balanced and blue printed less than 2 months ago

 

then why the injector treatment via-gas-tank?

 

Generally harmless because they are all snake oils or used at levels that are useless in the dilution.

The only one I have seen worth half its cost if the chevron techroline stuff and even then you must put it in a levels double or quadruple what the recommended amounts are.

But even the best at double or triple recommended amounts will only help very minor injector clogs. There is not a bottled substitute for ultrasonic or professional cleaning.

And as far as the other snake oils and quick liquied solutions pedaled at Jiffy lube or other quick buck auto repair places, the statement of so adding something into the oil system defeats the purpose of oil in the first place.

 

because i work at jiffy lube i get it for free why not keep my injectors as clean as possible

 

Icemark is saying that it probably isnt doing much. And if you had your injectors proffessionaly cleaned recently, then you shouldnt have to clean them. Are you having a problem with the fuel system?

 

well I should add then, that just because I haven't seen it doesn't mean that it doesn't work. But I have seen enough to say that most of them are just crap, so I am skeptical that any work well.

Kinda like the Slick 50 stuff, that the reason that you get extra power on a engine with it in, is because there has been proved increased wear and therefore the parts have reduced contact. Its not because of some magical teflon pixy dust mixed into the formula.

 

i use to work at a place like that that had those cleaners and the intake one said not for rotarys so i don't know if it would mess it up

 

I use to work at Firestone. We had a service we called "A 3 can." One can would go into the gas tank(fuel injector cleaner), another car would be sprayed into the throttle bore(intake tract cleaner) and the last can was slowly put into a main vacuum line. It helped clean out the vacuum lines and intake tract along with the carb cleaner stuff. The combination of the three cans was very effective on most cars. We had many customers commenting that there car hadn't ran that good since it was new. We recommended replacing the plugs after the service as they usually needed replacing before the 3 can service anyway.

 

if you wanna clean the carbon go to chevron.

 

Using the brake booster line on a 6 port will not only skip right past the entire intake track, it will also only effect the rear rotor. You are going to want to use that stuff further up in the system, preferably in the dynamic chamber.

I have had some success using the "Lucus" fuel system cleaner. I had my injectors cleaned at RC; but I premix so an occational treatment makes sense to me. And that Chevron Tech stuff is expensive.

 

no i'm talking about just going to chevron and getting a tank full of gas....

 

i know what stuff your talking about. We used to have a product( atthe garage i worked) called run rite. one bottle in the gas tank, one in the oil, and one dripping in the brke boosetr line. We used to call them "run wrong" cuz they would make the cars smoke like crazy and then most of them never worked quite the same again. good service for 60 bux dont ya think.

 

i'd just do the water trick and get chevron gas once a month. you won't have no carbon in your engine and no crap in your lines. just make sure you change your fuel filter afterwards

 

yea we had a product that did that **** everyones car up it was the same thing accept made by a different co. and we trashed it and went with this and have had no cars hurt because of it, aan yea i go to cheveron but what do you mean oh yea but i didnt use the stuff that goes into your oil because i really cannot trust that because it sits in your engine and cleans it out so that doesnt sound like it would be to good for my engine and seals so i only did a 2 stage system

 

I cant belive some peoples stupidity try to make others look dumb..

Rx-7Blazin
Is telling the truth,call up any of yoru local auto care shops..

Most people call it an induction/injector service..

Its a 3 step process
1 bottle in the tank
1 bottle to clean out the throttle body.(I use a old tooth brush to get in there and scrub the cabon out)

1 bottle the main checmical to run in your intake system through a vacume going into the intake..

What this does is,teh vacume takes it into the intake,to clean out carbon deposits and gum build up.

Of course since its going through your intake,it will get down towards the injectors,and the chemical dumped in the fuel tank will help flush it out also..Its not a 100% cleaning the injectors but more of a preventive maintence..

This will make the car burn black and white smoke out of the ehxast..

I saved about 5 bottles of the main chemical when I used to work at the dealership ..and still get some free ones when drop by..

This service runs about $100. at most shops..

I will be doing some soon free on some local friends 7s..

 

where are the injectors located on a 13b, and are they difficult to remove? procedure for removal?

 

i think i know what hes talking about. its a service that some oil change ploaces offer. its a two bottle service. one bottle oges in the gas. the other is poured into a metal container with a valve that then plugs into a vac line. you turn the valve and the vac sucks the second cleaner out of the metal container.

i have done this before. you buy the bottle of intake cleaner, not fuel injection cleaner, or any carb cleaner liquid. fill a dixie cup with it and pull off a vac line. put the line in the cup and it gets sucked through the manifold. no it wont clewan the injectors, it has to to through the fuel line to do that. doing this will only clean the intake manifold from the point you insert the fluid and down.

yes it will smoke like a bitch. not much of a performance gain, buit it will clean out any burnt oil and carbon deposits in the manifold. using carb cleaner is also stronger than the water treatment, or at least for doing the intake.

 

I'm never goin to Jiffy Lube!!!!

That fuel system cleaner is ****. I put a bottle in every 2 months for a year, and guess what happened after a year? I leaned out and blew my engine due to dirty injectors.

In a nutshell, I hit 115 and stopped accelerating like I hit a wall in my TII, after my injectors were cleaned (and a rebuild) it never happened again.

 

But the problem with what he is saying is that he is using the brake booster line for the vac feed... which again, So he did nothing positive for the intake at all. and there is no way anything could possible be cleaned except one small vac passage to the rear rotor.

 

Wow, this is a funny thread. The "Huge black thing behind the master cylinder" is called a BRAKE BOOSTER lol!!!

 

just looks like one more reason NOT to take your rotary to Jiffy-Lube. If you can't do the job yourself, find someone who KNOWS what to do with the rotary or you're just asking for trouble.....I heard of someone once who went there and they tried to tell him that they thought his PISTON RINGS were shot because fo the color of his exhaust......

 

No doubt... I should start offering that fuel injection clean up... $10 in chemicals, and a half hour of time, for a quick $60-$100.

I'll put it on the price list between Muffer bearing replacement and Headlight fluid drain and replacement.
