black smoke

Just wondering if this is normal. The only mod i've done to my truck so far is the kwik filter. Now before I put it on, I could never get any black smoke out. Now that I have it on and I press hard on a highway on ramp I can get some black smoke out for brief 2 seconds or so. Is this normal?

Also I was parking my trailer the other day and had the truck idling while I was getting it all set up, so when I was done I told my brother go forward and park the truck in it's spot, when he pressed the pedal down it shot out some blue smoke. should I be worried? It never blows blue smoke out on start up. Only a few times during the winter when it was really cold out. Anyways thats all the questions I have right now. thanks in advance for the answers.

zontral, the black smoke is not really much to be concerned about as it is unburned fuel. That's a good indicator your fuel system is up to snuff. The open intake likely allowed a better flow through the system getting that out.

As for the blue smoke, could be from the CCV residue going through. Have you done that mod?

Overall I'd say you're in good shape.

nah, the crankcase vapors will be completely burnt in combustion. it is normal for the smoke to puff lightly and then go away on a stock truck. hell even on my modified one, my airflow is so good that there is just a small haze after the turbo spools up. the blue smoke is normal when the engine isn't to operating temps.

Hell I wish my would poor black clouds. However I understand thats not a good thing, and I would be wasting fuel, but DANG it looks cool / tuff.

I getter smoken sometimes, hopefully more after the DP comes.

Side Note:
If I tell Jody I want a "black smoke setting" do you think he will hook me up, or just think I'm a dumba$$?
You know the black smoke is always good for those low-to-earth rice burners , and kids driving around.

i love it when the black smoke rolls get a 10 or 18k mod and it will . my truck would not smoke at all even with my hypermax chip but i put on a 10k mod and now i can smoke rice easily. i would ask for a black smoke setting also lol

Well, there's only one way to find out for sure. Ask the man himself. I'm curious to see what he says. Not that I'd want that setting myself, but just curious whether he'd do it or not.

OK, these are just my thoughts. Because you have opened up the intake side but not the exhaust, your healthy fuel system is overfeeding the cylinders, but it may not be getting out quite as efficiently. Mine would do the same thing before I got my 5" exhaust. Now I have a hard time getting that smoke.

Now I believe the other source of a lot of black smoke is from a poorly running engine due to an intake or exhaust restriction of some sort. I don't believe this is your case. I would think that if the truck is running good, I would be happy my fuel system is supplying ample fuel when I hammer it.

I had a weird thing happen the other week.. I am currently working a farm harvest job in MN up near Fargo so we get some cooler nights when I got off at 2am starting at 2 pm driving a sugar beet harvest semi transport truck..

We full time RV and are sitting at a old home site which also has some spare trailers and such on site,, ( 2 acres area) and less than 2 miles from the shop/farm so the engine does not get warm at all.. I always for the most part especially when cold out delay till the WTS light goes out.

This morning the temp was a bit cooler in the upper 30's to lower 40's.. When it started the engine felt like a gasser with a bad spark plug or wire that fell off... I let it sit for a min or so at idle and it contuined to run rough.. on the way back to camper still felt like miss.. I don't stomp on it as it was cold but during the acceleration it still had a "miss".. I did try to push it a bit a couple time but till did not smooth out..

SO next morning after waking around 11 am it was much warmer I again wait for WTS ligth to go out and turned key.. It started and i saw a bit of black and white smoke out pipe and still a bit of rough... I drove around a bit to get up to temp with the stumble and after a couple of good speritated runs it smooths out.. after that the crank time seemed to increase just a bit,, usually turn key and after less than 2 seconds it fires.. now it was taking all of 2 seconds..

Now after 4 trips to fargo airport to attend moms funeral and transportation for wife flying in from doctors appt in raleigh NC it now cranks like normal and is smooth as it can be with 269K miles.. I was thinking it might be oil related, just a smig low on stick, but oil was changed less than 2K mile on way back from Alaska while in Whitehorse at RV park with oil change area.

This is the first time I remember this happening and wonder if the miles could be a factor when it comes to injector life remaining. Over the past 3 yrs many of the miles have been towing a 8500 lb airstream around the country. I have alway run Hotshots EDT and couple months ago did the "extreme treatment" from HotShots, which I could tell made a nice difference in power especially when towing and pulling long 5-6% grades on way back to MN in canada especially on icefields parkway..

I checked fuel filter and it looked fine but no way to measure if there is a large engoung blockage to create a problem as it runs fine now..

guess it was just a week or better of not getting to temp running 15w40 oil.. on next change might be looking to do the 10w30 as we are heading to the north west for a bit till heading south to CA, AZ for winter.

any idea as to this strange occurance??

your main issue, is Lack of Charging Time to keep the batteries fully charged.

I just had the same issue with my truck, it was at a shop for 3 weeks,
he started it each day and moved it outside while working on something else.

his thinking was " that will charge the battery enough to keep it up "
well, it didn't it made things a hell of a lot Worse....

I knew how he does things, and had the batteries at 13.34 floating before I took to him.

when I picked it up yesterday, the DVM showed 12.1 volts, well below full discharge.

it cranked and started up, but more sluggish than usual.

I drove it 4 miles to the house, and the voltage was at 12.3 when I turned the key OFF. this is NOT a lack of Alternator power capability, as it has a 320A alternator on it. It was pushing 14,8 for those 4 miles, but the LACK OF TIME to charge didn't even begin to charge the batteries up.

I had to put it on a charger last night, at 7 am it was up to 12.88 volts,

is there anyway, you can put a solar charger on the truck or have access to 120 VAC to use a regulate charger?

If you're referring to me lack of charges not a problem because I'm driving about 3 MI to 4 MI but I do Drive sometimes during the day between shifts 45 to 50 miles so the batteries are fine it was just a weird one-off thing that happened that one morning and the next morning but it seemed to be fine.

and it hasn't done it since.

7.3 injectors ARE a wear item. Expected lifespan is 200-250k miles. You'd probably benefit from a new set.

Pretty basic, but Diesels aren't gas engines. Even the newest ones will misfire and smoke when they're cold-started. As long as it wakes up & smooths out when it warms up a little, that's just fine.

I hear the 200 to 250 K miles on injectors and have to say I think that is "poppycock" LOL.. I currently have 268K miles on far as I know OEM injectors from sept 2002 build date on 2003 yr model unit.

Currently near fargo ND and temps have been F"ing cold.. currently its 19 degrees.. When i started up couple hours ago after waiting for WTS light to go out i then count to 3 and turn key,, To start took just a smidge longer at 3 seconds to fire off... I did notice a bunch more blueish white smoke out the pipe for a good 10 mins of high idle but after a bit it cleared and has not smoked since..

I hear is you have issues with cold starts the injectors might need to be shimmed at the armature under the solenoid.. My cool starts, 40 or so is 2 seconds after turning key.

I am running 15w40 and will be changing oil this week and adding 2 qts of hot shots stiction eliminator to help give the oil side of motor a good cleaning as I have never done any oil additive other than archoil on time several years ago. I usually run Delo, MC or walmart supertech oil .. I do run a fl2525 bapass oil filter as well and the UOA show no to very little soot in oil when checked.

on fuel side I do run every tank EDT hotshots as well.

I will post video of smoke at start up in next message.
