I wanted to throw a can of BG 44K but I read in a thread somewhere that fuel injection cleaning doesn't take well to the VG injectors. Is this true?

 

it is true

 

what about ve injectors?

 

so that means i can't properly maintain my injectors?

 

properly maintaining them means using good gas.
anything beyond that may strip the coating off the windings in the injector leading to premature failure

 

well even then there is still going to be build up. The car is 17 years old plus I don't know what was used in it before i aquired it.

 

It means if you will simply use a high quality gasoline(shell/chevron/mobil/exxon/etc.) you will be fine until the injector fails(nissan injectors usually fail mechanically,not clog)

The main brand gasolines companies put cleaning agents in their gas to combat clogging/varnish buildup,so using concentrated versions like "BG 44K" are pretty much useless,and in some cases harmful.

edit; brian types faster than me

 

Guess I am going to be getting another reprimand from Wayne to tone it down, but this really needs to be said:

Of all the bull**** arguments to substantiate wishful thinking as fact, that just about takes the cake.

I am so tired of people with huge post counts making garbage comments with no substantiable basis of truth. The fact that you are involved in an industry does not make you an authority on anything if you are going to start and propagate arguments based on hearsay only - we all know how high the average mechanic value his integrity.

I refer you to my last attempted discussion on the subject with yourself where you snidely commentedWell - guess what.

This morning I was looking through old photos and happen to actually bump into proof of my own assertions based on experiences I had during investigations on the subject.

Here is a set of self-explanatory photos I merged together of a known Working VG injector I butchered to see the exact inner workings of the animal.

From that, it is quite obvious that:

1. The injector's electrical coil is molded in plastic - just as I said.
2. The injector's electrical coil never comes in contact with fuel - by design - just as I said
3. As a result, there is no way for any fuel additive or fuel cleaner or whatever liquid, to affect the operation of the coil if the plastic coil former is still sound and no holes have been mechanically poked through the plastic and the injector's side-fed holes.



Now - I would appreciate you and anybody/everybody else stop spreading bull**** rumors based on hearsay only, because it would seem you, the re-builders you talk to, and also Nissan are all sadly mistaken. .................... its really as simple as that.

 

Perhaps.... you know.... if you found a ladder, and got up on it....











You could get your nose even HIGHER up in the air.




You're not even contributing to the post at hand, he was asking if INJECTOR CLEANER would help prolong the failure of his injectors, or possibly clean or fix his dead injectors.

It doesn't take an electrical engineer degree of any aptitude to figure out that WITH EXPERIENCE, as Brian has, that the common reason of failure of our cars' injectors has to do with an electrical impedance problem, and mechanical failure, rather than dirt build up. Regardless of what the coil is molded in, cleaning agents and injector miracle bottles only lead to problems down the road.

What is with people proving that they are right instead of just contributing to the thread and HELPING the person. Jebus Christ.

 

................. and I guess the person asking the question because he doesn't know the answer and is not in possession of all the correct facts of the issue, is expected to magically know when somebody is truly helping him eh?

Sure - we can chose to all live together in perfect harmony and eternal blissful ignorance, but I for one refuse to simply plod along - so why don't you now learn from real-world and relevant experience too ISO again referring to a person's supposed untouchable reputation alone as being helpful.

 

You can present facts and information in a more general, less condescending, kind of way. I, in no way agree with the "ignorance is bliss" phrase and never claimed to. However, when representing contradicting evidence as you just did, you don't have to ignore the question of the OP and go about attacking Brian; I always find your posts a bit displeasing to read, regardless of how insightful they may be.

 

Point taken and I will certainly work on that.

Allow me though to make one further comment relative to the thread topic and advice given here in print already:

If you go back and read though all threads mentioning/discussing fuel injector cleaners and their pros/cons, you will always (as far as I could track) find Brian posting the exact same warning re the injector coils getting negatively affected by fuel/additives. Now I have on various occasions tried to approach the subject from a "discussionary" standpoint, but have failed on every occasion because of Brian's attitude that he knows what he is talking about sans any proof ......................... yet, again here we have the same warning getting posted as fact and as such attaching a perceived stigma to the poor design of these injectors.

Please forgive me for sticking to demonstrable facts and dispelling myths wherever I bump into them - you may view my comments as "ignoring the question of the OP" but I disagree. Sure I could have responded "no, its not true" to the intitial posted response of "it is true", but exactly where would that have left the OP? - on average exactly where he started. From past experiences, I can predict that this thread will not have a definitive conclusion because just as in so many other similarly titled threads, you will probably have as many people saying yeah as there are neah sayers - and both groups will be able to support their views based on their own past experiences - me? - I would rather drink beer for that money if normal maintenance has been properly carried out on the vehicle .................

 

HOLY MOLY! That was some page! I'm on slow DSL, and it still took me a while to load that page. For many's convenience, I chopped them up into smaller, individual images (so observers would have to view the entire large image to see 1 specific image). Loading for me almost made me

I'll host them for as long as I can...





Hey, I'm an EE too! Not the best EE, I'm just the lazier of the bunch.

And to add something to the topic... my car does the same thing... I'll check grounds too! It'll be good, because my speakers whrrr with my engine RPM. So there's definitely some wiring issue somewhere.

 

dog gone 5image limit. Sorry.




BTW, this is out of curiousity of the function of the filter-screen (green arrow)
Does fuel flow out from the green arrow? red arrow? or both? Sorry if the answer is obvious.

 

No problem - fuel flows from the pump, to the fuel filter canister, into the rails where the injector is "pressed" into a machined orifice and where fuel is fed into the sides of the injector body through that screen at high pressure. Your injector then opens its tip under control of the 2 wires connected to it and fuel get "sprayed"/atomized out the bottom (your red arrow) into the inlet manifold port for that particular cylinder

Guess the function of the screen is a last barrier to prevent particles not caught by the actual fuel filter canister from entering and interfering with the predictable operation - typically nothing if motor maintenance is seen to properly
