ideas please

[mattsn]

guys, i need some opinions. last few weeks ive started the truck up in the cold mornings ( 30* to 20* ) and get a short puff of light blueish gray smoke. This morning i started it at 18* and it smoked the blueish grey smoke like a train. I let it idle for bout 5 mins and it was still smoking. went down the road about a mile before it cleared up. Now, it ran and idled smoothly and the color was not white like it was when my EGR cooler went up. Im thinking maybe bad injector or two? maybe even a bad EGR valve. I do have the latest inductive heating flash and my EGR valve is turned off, but its not really white like steam so im thinking it is not coolant related. the truck sat all day today started it to come home and just got the normal puff of smoke. it was 35* Any ideas?

i am pretty sure that there was a tsb about the white smoke..and it said that it was normal. Mine smokes the same way..every morning.

mine is a little more extreme.

LMFAO, you should see mine roll the coal on startup.

[mattsn]

really, normal? it just started doing this a few weeks ago. huh, ok you two are smarter with these trucks than i am. and its grey not white

[bones]

mine does it in cold weather

Light grey is unburned fuel from cold cylinders
Light blue is burned oil
White is coolant
Black is over fueling/lack of oxygen.

yep, this is why i knew it wasnt coolant and figured an injector might be bad. ok its nothing to worry about , but still weird that it never happened last winter. thanks guys

[Abrannan19]

but still weird that it never happened last winter. thanks guys

its because of the 'global warming'

[mattsn]

Lol

I just viewed the video you posted and my truck was 10x that yesterday morning. but the difference may be that it was colder here. i notice the florida tag in that truck. couldnt have been 18* there

[Abrannan19]

that video was about a year ago..I think..it was cold but I am sure not 18*

[mattsn]

so im assuming the colder it is , the colder the fuel and the cylinder is meaning, the thicker the smoke?

[Abrannan19]

that would be my assumption..kinda like a gas motors' exhaust smoking at idle..in the cold I mean.

White can also be unburned fuel. Looks like a fog, smells strongly of diesel.

The smoke in the video is fine at start up, especially on cooler days. It should clear though.

If it is 10x that bad and it was not nearly that bad in the past, it is not normal. Could be injectors starting to go (spool valves). I would also check HPOP pressures. If you are low (but high enough for it to want to fire, which I think is triggered at 500psi), you won't get as good atomization and when she is cold, you will get more soot in the exhaust and it will look a lot darker than the attached video.

As the injector warms, the spool valves may work better and that will improve the problem (if it is an injector issue). The HPOP pressures may also rise when the engine warms and again the problem would go away.

I would not think 10x the smoke in the video is ok, especially if that is a marked change from how your truck ran last winter.

never seen you on this forum before, always on TDG

[ralphinnj]

Was just poking around.....made an account here a long time ago....I should get in here more often.

[Abrannan19]

I should get in here more often.

yes you should!

My 225's smoked worse than Adam's truck when it was 85* out for the first 5 minutes.

[Carssuck]

If the oil is old and oxidized it will be thicker and help cause the smoky start up (more than usual)
Both of the 6.0s I have owned do the same as the clip. Again, if the oil gets too thick, it will smoke more.

[mattsn]

my oil is never old. i use synthetic 5w40 and change it every 5k

[Carssuck]

At 5k, your oil is just about on it's way to being heavily oxidized even synthetic. I have yet to find an oil that will safely carry me past 5k miles using an oil analysis. I just got my sample results back yesterday for Schaeffer's 9000 5w 40 synthetic and the report only recommends another 1000 miles to dump. I changed it anyway. The fact that I work the truck pretty hard with trailer pullin' and lots of short trips in the city might have something to do with it.

I have sampled a whole bunch of oils and I am looking for the longest lasting with disheartening results on many different synthetics!

My point is, pending on the oil, my truck would begin to start funny and smoke more with as little as 3000 on the oil... Shell Rotella 5 40 syn was the worst, for what it's worth.

[mattsn]

I agree that 5k is at the end of the oils usefulness that is why i change it then. Ive done several reports and all come back with good results. the oil in the truck right now only has bout 1500 miles on it so its really clean. hasnt been cold here the last few days so i havent seen the problem since.

[PSDPlayer]

Its a combination of cold oil retarding injection timing. The cylinder not up to combustion temps cause it cant heat the air from 18 degrees to 700 that easily. And the fuel not wanting to atomize. Then with the tune in it, it gets confused as it tries to compensate but just adds to the problem.

[mattsn]

thanks doug, so im fine just to ignore it ? nothing to worry about? still wierd that i never noticed it happening last year. is this tune any different than the original one you wrote me that i was using last winter?

[mattsn]

?????????? Doug got an answer ?

Whats the best oil you have used and tested Jay?

Whats the best oil you have used and tested Jay?



To this point, I have tested:
Shell Rotella= shit after 3000
Schaeffer's 9000= shit after 6000
Mobil Delvac 1= semi crappy after 7000
Valovline premium blue= same as Mobil (same life)
Amsoil= shit after 9000
I was really pissed that Amsoil didn't hold up, but it was more a problem with customer service. It is the best so far and I still will not use it (it's a matter of principal)

I am trying some stuff that the engineer who has been testing my oil has recommended, he says it's the best oil he has ever seen and is supposedly able to sustain the longest interval. It's called TRC Moly XL Pro Spec 111
http://www.texasrefinery.com


I just put the stuff in a few weeks ago, so we will see.

The problem I have been consistently having with both my 03 (gone) and my 07 is oxidation. I seem to oxidize the hell out of my oil because of the way I work the truck, this is when it starts to miss and smoke on start up. The one thing ALL of the oils I have had analyzed have in common is, all of the additive packages seem to hold up except for the antioxidants.

Keep in mind, I do have a bypass oil filter.

I would also imagine all of these oils would hold up better in a truck that isn't worked so hard.

Finally a straight answer on that. good thing it doesn't get "too cold" in CA.

carssuck, any experience with 15-40 Delo?

I beat up on synthetic oils so bad, I have decided to steer clear of non-synthetics.. Sorry.

[darsey715]

thanks for the reply sir. what oil are you currently running

[mikeym]

my truck smokes and stumbles so bad in the morning its ridiculous. speaking of which...

hey doug, what about those tunes we talked about last week?

[mattsn]

thanks for bringing this back on topic
