White smoke at start up....

[BillyGHusk]

After a quick search of the board and reading some of the posts I'm still not sure which answer this could be.

3B with a little over 70k miles,

I have been running B99 most of the time and dino when I can't get to the bio station.

At start up after the engine has been off for 5+ hours, I get the "smoke show"(read that in another thread).
Mostly white in color, could have a slight blueish tint, but I would call it mainly white.
Smokes good for 10-15 seconds and once I get going seems to go away.
The rig is a fj60 so I have a button I push for the glow plugs, I typically hold it for 5-7 seconds and give it have a pedal, it will start and the die, glow plug for 3-4 seconds and she starts up stays running but billowing the smoke.

From what I read I guess it could be the glow plug system or the diaphragm thoughts?

I think I have noticed a bit more smoke from the tube that runs down and out the bottom of the engine(see photo), I think I am noticing it at stop lights and such, I am very new to diesels in general and have had this rig for about 2-3 months so still figuring out what is normal.

Thanks in advance and I am happy to answer any questions I might have left out to help diagnose.

Try a full tank of dino fuel. There have been others on here with similar problems from using bio.
Its possible not all the water has been extracted from the fuel.

The diapragm is definately worth a check but other reports mention high idle speed.

I have a button for the glow plugs ,but I have to hold it for 10 seconds. I will check the power supply one of these days.

If your getting a bit more smoke from the crank vent pipe,have a compression check done if your worried

[Spore]

That pipe is a crankcase vent. It allows blowby to exit the engine. If it's billowing smoke (excessive blowby) you may have a ring problem, etc.

[Eric Winkworth]

maybe your injectors need a service, sounds like your glowing long enough for a clean burn start....

injectors have a lot to do with how a diesel runs... you say the smoke has maybe a bluish tint, does it use any engine oil? I wouldn't worry too much about that crankcase vent unless you are noticing oil loss, or coolent in your oil...

[Eric Winkworth]

then again dead cylinders in a diesel isn't a good thing...

if I were you I'd get a compression test, that way you know if you do have some rings that didn't seat properly, and if that comes back good, I'd service the injectors... I also think running some Dino through it and a good amount of injector cleaner/fuel conditioner, could work wonders if the bio has varnished your injectors...

[83bj60]

The others have suggested excellent ideas about the glow plug system but look also at your driving habits and what it can do to the injectors and the fuel you use and the deposits it can cause (injector tips and rings) if the combustion is not perfect, if it's running cold too often or if you drive conservatively most of the time. Your truck may simply need a nice high speed highway drive for a few hours to clean itself out. Although it is said that bio is a great lubricant and detergent, I wouldn't take chances and do that with a tank of dino plus injector cleaner.

Also if the engine oil you are using is not diesel spec (they are very high in detergents), it may not be able to clean the engine enough and may lead to deposits.

Hope it helps.

Thanks for all the feedback....

I will give that a try, however the place I am getting my bio is a large company. I would expect that is was done right, but then again I see large companies doing things wrong every day!!

look also at your driving habits and what it can do to the injectors

That makes sense and hadn't thought about that I am a fairly conservative driver with only 10-15 miles of freeway driving a day, most of that 55 or under.

Also if the engine oil you are using is not diesel spec

I just started using Amsoil Diesel 10w40 with the last change so perhaps that will help.

Any specific suggestions for injector cleaner? I am assuming there is diesel specif cleaner/additive.

Other than the smoke at start up it runs great.....

Will keep posted what I find out...

All the ideas above a good, but start with the basics 1st. Get a multi-meter and an engine manual. Check to ensure the glowplugs are getting juice when you press the button. Do a continuity check for each glow plug, to ensure they are still good. Then...move onto the rest if these do not work.

A valveset, compression test, and crack test for the injectors are all good things to do so you know where things are at with the engine.

As Greg said, have a look at your glowplugs. If your using the "Wilson Switch" you should have 10.5V plugs and they are not that expensive or hard to check/change. With my push button system I was holding it 10-15 seconds on a cold start.

Bet on glow plugs .. how much time you get in thos old glow plugs . ?

I found here those ones .



in less of 30 bucks all 6 for my 12V 2H .. 2 hours ( with patient and top mounted intercooler ) to replace ..

?! SIX BUCKS ONLY per glowplug?! Quick, send me a dozen cases!!! Care to tell us where you get such great deals? Do they have deals like that on other glowplugs as well?

No shit, I paid 60 bucks per. Ouch!

[BillyGHusk]

[quote=Tapage;2570185]Bet on glow plugs .. how much time you get in thos old glow plugs . ?

Well, all I know is the engine has about 70,000 miles on it......


Sounds like a good deal....I will get some of those, even if I don't need them now I will at some points!!

Thanks,
Tim

You can get them on aussie ebay most of the time.http://cars.search.ebay.com.au/glow-...ofocusZunknown
Ive been using the HKT plugs for 2 years(I thought I had some from China) and they are ok,fairly common replacement plug in oz.

Dealer wanted something stupid like $60 ea for the ND plugs. One of the biggest and best diesel shops here says they are as good as the ND plugs.

I get a bit sick of hearing you must use OEM only when its plainly untrue.

I paid about $7 AUD each for mine.
I think the 1HZ use the PT 152 but I would have to check.

Actually they are about 8 USD ea ... but with my discount I get 'em at better price .. and course, I can buy a lots .. but I thought the shipping would cost the other part of money ..

Here we can get some cheap thinks .. coz we have a huge port in Pasific and Caribean seas .. so maby of Latin America Distributor keep huge headquarters here and make the distribution for the hole are from here ..

I hate to say you are all wrong, but...

Timing timing timing. Did I mention timing?

I chased down the white smoke dragon for months. New injectors, new glowplugs, manual override on the glowplugs etc. By chance one day I met with the diesel mechanic at the local Toyota dealer and he looked at it for 5 seconds (literally) and said "timing".

Loosen the bolts and rock the entire pump assembly towards or away from the block (mark it where it was first!!). Towards the block is advance and away is retard (I think, it's been a while). To do it properly you need a chunk of tube of the same diameter as the injector lines (preferably an old injector line piece 26 mm in length). It is all outlined in the FSM.

Seriously, no cost involved, and you will be amazed at the results. Try it first before you do all that other stuff.

The reason it needs adjusting at all is the springs on the timing gear wear and do not give the same resistance as they used to.

Hope that helps,
Craig.

timing huh....

well I do like the idea of a fix that doesn't cost anything....

from my days of running a gas engine, wouldn't the timing being off effect the way the engine runs all the time, again, I am VERY new to diesels and looking to learn. So if I post something that is dumb drop kick my **s!

Tim

[Greg_B]

Yes, excellent advice.

Well thats why I never included timing in my 1st post but it worth a check. It maybe only out a little and the warmed up engine is covering up the symptoms somewhat.

White smoke is combustion that is too cool. The fuel is reaching the cyl walls but should have burnt before it gets there

[BillyGHusk]

regarding timing...

Is there a way to check the timing like a gas engine....with a timing light/strobe?

Tim

[lumpy70]

As for affecting the whole running of the engine...yes, you might not notice the loss while it is running or warm, but it is there. At start up (and this was on a fresh rebuild) it was a horrendous and smelly smoke show with it bucking and snorting and being virtually un-driveable until it warmed up. It made me very popular at work.

I moved my fuel pump between 1/16 and 1/8 of an inch and that was all the difference. It's very sensitive.

Again, MARK THE SPOT on both the pump and the bracket that holds it before you start. To do it right find a chunk of injector tube and follow the FSM.

Craig.

[lumpy70]

Yes and no. Can you check the timing? Yes. Is it like a gasser? Absolutely not.

Please see the attached pictures.

I have a manual glow plug switch on my 3b.

I glow it for 8 seconds before starting

fire the engine......

and glow it again for 2-3 seconds while idling.

I can start it w/o lil to no smoke doing so.....

It's the glow system design to run when the engine it's running . ?

no, it's only for cold starting

Yes, that essentially is what the superglow is doing: Hits the plugs with high voltage for a few seconds, the light on the dash goes out, you start the truck and the super glow tails off the voltage till it reachs 0V...while the truck is running. When the superglow is bypassed by a manual system it is ok to give it glow to smooth out the idle (and or keep it running when it's really cold) for a 1st little bit.
