by lower quality injector builders would ya be referring to full force diesel by chance cause that’s the ones I chose really wondering why now but anyways I did pull my covers replaced o rings on 2 injectors and now back running but damn it sure puts out a thick gray cloud of smoke what the hell is my problem?

QUOTE=SkySkiJason;19915955]There have been several reports lately of failed injector o-rings coming from the lower quality injector builders like the ones who build ‘180/30’ injectors. But, o-ring failure usually doesn’t cause a no-start by itself.

You’ll need to do some more testing. Buzz test, KOEO and monitor ICP/IPR DC while cranking.[/QUOTE]

 

Smoke could be leaking nozzles. We've seen other builders using Chinese nozzles...

 

is there anyway to know or since ur in same state as I I’m really wishing I woulda chose ur injectors right about now

 

Thorough injector testing can only be performed with them removed from the vehicle unfortunately.

 

well I’m real close to putting stock set back in from another truck but I emailed ya on ur web site needing to figure out some op

This is the number 8 those pits were not there 2 weeks ago but I was told to replace orings and reinstall would this cause me problems like ones I’m having now

Maybe there is something in your fuel.

 

I do have the fuel rail cross over set up on there so I would think maybe that help get fuel through filter faster but I’ll change my filter again less ya got other ideas

 

The pitting after two weeks in concerning.

 

now I can’t even drive to fuel station without smoking out everything and everyone around

 

The more conventional explanation for pitting corrosion is that it is an autocatalytic process. Metal oxidation results in localized acidity that is maintained by the spatial separation of the cathodic and anodic half-reactions, which creates a potential gradient and electromigration of aggressive anions into the pit.[1] For example, when a metal is present in an oxygenated sodium-chloride electrolyte, the pit acts as anode and the metal surface acts as cathode. The localized production of positive metal ions in the pit gives a local excess of positive charge which attracts the negative chlorine ions from the electrolyte to produce charge neutrality. The pit contains a high concentration of metal (Me) chloride (MeCln) which hydrolyzes with water to produce the corresponding metal hydroxide (Me(OH)n), and n H+ and n Cl– ions, accelerating the corrosion process.[2] In the pit, the oxygen concentration is essentially zero and all of the cathodic oxygen reactions take place on the metal surface outside the pit. The pit is anodic and the locus of rapid dissolution of the metal.[3] The metal corrosion initiation is autocatalytic in nature however its propagation is not. This kind of corrosion is often difficult to detect and so is extremely insidious, as it causes little loss of material with the small effect on its surface, while it damages the deep structures of the metal. The pits on the surface are often obscured by corrosion products. Pitting can be initiated by a small surface defect, being a scratch or a local change in the alloy composition (or local impurities, e.g. metallic sulfide inclusions such as MnS or NiS), or a damage to the protective coating. Polished surfaces display a higher resistance to pitting.

The removal of material on that injector is surprising. It does not seem likely that amount of material could go poof so quickly by galvanic means. Ya sure the injectors did not have those scars before? I could see that as a well cleaned surface of an injector that enjoyed rust for a few years in a junkyard somewhere. No expert here but I do not think that surface is critical anyway. As long as the o ring grooves are good. Don't think that is the problem.

But hey, that's all guess work from miles away. Send that pic to FFD with description of symptoms, see what they say.

But like the man said, could be something in your fuel. Put some in a styrofoam cup. If it melts it has gas in it.

 

Yes, that is one of the low quality injector builders. I’ll bet a 6-pack of beer you will be told you have/had a fuel issue. Take a sample now and have it tested.

It’s difficult to believe that damage happened in (2) weeks and impossible to imagine how it could be just one injector.

Are you monitoring fuel pressure? ICP/IPR DC?

 

How much driving did you do after re oringing the two?

 

at total of 40 miles so far

 

alright well I got few samples of fuel already from when I figured out I ended up getting oil mixed in so who could I send these samples to for testing? I’ve heard of it just never did hear of who does it
