Smoke in the head lights

[promisedland]

HELLO to all!
I'm bugged at the haze that i see when these newer cars follow me with there super bright lights and when i start off it looks like i'm drivin a steamer by the haze i can see in my mirror. At daytime i really dont see any unless i'm towing heavy or feel the need to stomp it. Do you have some input? Stock inj as far as i know. Smarty on SW5.
Thanks!

Normal,smarty on 5.No worries

 

[GrantP]

Pretty normal for stock too if you get on it. I don't see it otherwise.

 

[promisedland]

OK,... i was hoping for a 'silver bullet' ...
Thanks!

My 06 stock in sig does the same. [99+k miles] Especially if in heavy stop and go, then mash the skinny pedal. Will puff a bit then clear..... Shows up more at nite....

I didnt know if my eng had wear [runs/starts great] or if this is normal.

my 2006 with 99k miles does this too, especially when cold. I only see the haze at night when someone is following me with their headlights on. Wish it didn't, but it seems to me thats just how it is. Oh, and my truck is stock tuning wise, but has a straight pipe and 35's with a 3.73 rear end.

I hear that folks who go with UDC custom tuning are able to get rid of this... any thoughts?

My mechanic said he heard a slight miss so maybe new inj are in my near future.. could this [haze] be dribbling injectors...?

It won't clear completly without a Filter and screw down the power to zero, especially not with the low quality Diesel you have over there.

There is only one thing you can doo - life with it or sell the truck, it wont stop hazing - its a Diesel.

 

[Ozymandias]

......of course you can throw a lot of money on it. Thats your decision but it wont solve the "Problem".

 

[promisedland]

Exhaust filter? No thank-you!
I wonder if my injectors may be dribbling some...
Maybe it is normal, but it bugs me!

Correction, in daytime i can see some black smoke in normal driving if the lighting is right. [in my mirror]

Some folks claim less smoke with custom tuning, Smarty UDC. And now we have HP tuners as an option....

 

[avvblanc01]

Yeah is there anyone on here that has a fresh set of stock injectors? I wonder if its just that my injectors are getting a little long in the tooth. Mine obviously hazes when i get on it, but i can see it at night even with very gentile acceleration

I was getting the same when I had about 75k on the clock. I thought it might have been cause by the 2 stroke I've been using. I used injector cleaner for a few tanks and it helped a lot. It didn't clear completely, but helped. Have you tired an injection cleaner ? After all it's a diesel, and its heavy fuel we throw in it.

 

[avvblanc01]

I do use optilube every other tank or so. Ive never really thought about the haze as being abnormal till I saw this thread, but then i figured why not ask.

Thats comletely normal to see a little haze in thenlight of following traffic - every diesel i have ever driven did this.

More questions = more answers!!
I just started using Power Service and 2 stroke oil. Although using 2 stroke seems kinda weird! :O

I asked some folks that are using UDC or HP Tuners [new, kinda like efi-live for 03-05 Rams] and they claim cleaner running with this tuning. As of now, i'm, just listening and watching...

I also would like to know if NEW injectors would help with this.

 

[AnOldBiker]

I don't see how any tuner or mechanical changes are going to make it a 'perfectly clear exhaust all the time'. There are other factors here to consider and not mentioned here. Was the engine up to temp and the exhaust dry when this happen ? Or was the exhaust hot and the outside air cool / cold with moisture in it ? Mileage on the injectors set ? Prior owners and their maintance ?

But if it would make you feel better, pull the injectors and look. That would the quickest way to see if they need to be changed out.

My two cents would be to not use two stroke oil with the HPCR (high pressure common rail) fuel system on your 3rd gen. The tolerances on these injectors are 25 millionths of an inch clearance, and they were not designed to flow 2 stroke oil. I know lots of people will recommend it, but I for one will put in nothing but the nicest fuel additives, or just the regular old ULSD that they were intended to run on.
Here is a direct quote from a TDR article: "Again, DON’T add used engine oil, transmission uid, and other junk to your fuel just because an old-time trucker said to do so! Stan Gozzi of Chrysler related to me how a fuel shop technician told him to paint the pintle of an injector with a Magic Marker and then try to replace the pintle into the nozzle. It won’t fit because the clearance is too tight. If you force the pintle (needle) into the nozzle, you will wipe off the Magic Marker! That more viscous “stuff” that you add to diesel fuel will cause problems."

not trying to start a problem, just trying to save you from one! haha here is the full article on our HPCR fuel system if you want to read it: http://cdn.genosgarage.com/downloads/TechPDF/TDR72_HPCR_Injectors.pdf

Thanks! I'm pondering....

I am sure the articles say a lot of things, just as I am equally sure not one of them has come out and said "this product is bad" for your fuel system and actually named it. What needs to be portrayed is a valid comparison of something that makes sense, like molecule size for example, of additives that are being represented as potentially "bad". Better yet, maybe a comparison of the MSDS of diesel and the additives to see what is actually IN them?

A better question for the pundits is how are these additives that are designed for lubrication so much worse than the asphaltenes that cook out of the ULSD in the CR systems? Since the CR's ran just fine on LSD fuel it is hard to buy into this hype when it is fact that long chain molecules in LSD were magnitudes larger than ULSD. It makes about as much sense as stating that sulphur in the fuel added lubrication, just not even on the right track.

Now it seems that the real determination of an additive is it has nicer properties. What the devil does THAT mean? I cannot find that measure on any labeling or MSDS sheet available for any product. What I do find is that amazingly all the additives are pretty much the same constitution with the obligatory secret component in varying amounts usually les the 20%, 2 stroke oil included if we really want to stay on point.

Things like this "The tolerances on these injectors are 25 millionths of an inch clearance" get propagated as something with actual value when they are patently false. It doesn't take much to figure just how wrong that is. Best information we have at this time says 2-3 um is the CR injector clearances, that would be something like 7 one hundred thousandths to 1 ten thousandths of an inch. On the scale of size that is magnitudes larger than 25 millionths of an inch. BTW, the bulk of this information is coming directly form Bosch engineers not the customer relations management division of any manufacturer.

Sorry, put comparing magic markers to 2 stroke oil just doesn't make an impression. Definitely one for the circular file.
