80 series smoking

Post by **macuserau** » Thu Jul 17, 2003 10:50 pm

does anyone know how to fix or why my 80 series turbo disiel is making a lot of white smoke and won't idle. If i pull the hand throttle on it will run but no idle. is it lack of fuel or is it sucking more air plse help me :?:

What did you do beforehand, drive through water??

The white smoke is unburnt (raw) fuel, which means that its not firing on one or more cylinders.

no water crossings, it started out not idleing (unless the hand throtle was on) and progressed into the white smoke. And it is running rough now as well.

i know of two people who had this happen with their 80's and it was the turbo causing the problems... 1 had to be rebuilt and the other replaced.

White smoke is condensation in the exhaust caused by an air leak in the fuel system. Unburnt fuel is black

Partially burnt fuel is black

White smoke is unburnt feul my cruiser is getting a little tired
and when cold, starts up one pot at a time blowing white smoke until
all pots have fired. your probblem sounds tubo related ''ouch''
Even a small pin hole in a diesle fuel line letts in air and stops it
dead. this happened to me last year.not good when your in the middle of the river and the hole is just under the car.

I am interested in all posible answers to the problem. I have asked a few people and some are saying loss of compression will cause the white smoke. Others say it is lack of fuel due to air and others say turbo oil seal.
If it was turbo oil seal wouldn't the smoke be blueish in color. I have also noticed that if i prime the filter it runs better, then after a while the smoke gets worst (although there is still smoke while it is running better just not as much) and the truck runs rough. if i then reprime the filter with the pump the truck runs smooth again (still a little rough though) and as i give the truck some throtle it boggs down the picks up the revs sometime or it stalls.
I am not sure and i am after some advice before seeing a mechanic as i have allways had bad runs with mechanics

anyone know a good mechanic in nowra area :lol:

Correct. If it was a turbo seal even a small amount of oil would find its way into the cylinder and create blue smoke.

Is it driveable at all? Or wont the engine take any load at all before stalling?
A siezed turbo could strangle the engine(lack of sufficient air) but it more than likely would be black smoke though.(partially burnt cos the engine is still firing and running rich)
Eliminate the turbo. Have you pulled off the air intake hose from the air cleaner to the turbo to see if the impellor is siezed? If it turns, does it turn whilst the engine is running?
Curious, when did you last fuel up and was it a good servo? I've seen a few L/rovers at work with half a tank of water do something similar.

What else is it doing?

i haven't checked the turbo physically, i will do that when i get home tonight, but the turbo light on the dash indicates that it is also you can here the turbo winding up. The fuel i have been to different garages and there is no evidence of water in the water trap. Some times you can drive the truck other times it takes up the load and stalls. as i said be for it is a little rough running though. and the more revs the more smoke (of cause)

Berrima diesel is about the best in the country. They are a little $$$$ but worth every cent. And they are not too far from Nowra. They also have a bed & Breakfast there now I think.

thanks for that but i had already rang them and they expressed that they could not help me, in terms of the scope of the work, they spoke on the phone for an hour trying to give me a way ahead. They suggested some one who had engine rebuilding capabilities. Rinheart (Berrima diesel's head mechanic) was a good help on the phone.
i guess i will have to bite the bullet and spend the $$$$

Bugga, sounds expensive then.

Let us know how it goes and what it was.

Post by **macuserau** » Thu Jul 24, 2003 10:18 am

it's with the mechanic today. what i found before it went to him was that i had an air lock in the fuel system and my timing was out as the camm came around to TDC the crank was past TDC, so i adjusted it as well. i also found that 1 injector was not working, by cracking the nut on the back of the injectors individualy and when the enginge almost dies then that injector is working. But i had one where there was no change. so i am getting a mechanic to do the tips and nozzles. at $538 the set including fitting. thanks to every one for your help. I will let you know if the mechanic finds more than the injectors.

i have just got my sweet runnig truck back from the mechanic. turns out that the number 6 injector was stuck open and that the other 5 where cracking early. 400 psi early. i also got the 80 series making oil problem as well, but now it is fix and running real well thank you to all that contributed to the help.

Your advanced pump would cause the white smoke.

MACUSERAU, where did you get your truck done and what did it set you back? am having similar problem

Post by **macuserau** » Tue Jul 29, 2003 2:58 pm

my truck was done at premier vechile service in quinns lane nowra. 44218713.

i have a 1hdt and the injectos set me back $550. but i have a little sugre at high speed ever now and then and the car wont idle still, the mechanic is going to over haul the pump. as there is no fuel coming out of the fuel return line from the injectors, i have check for blockages and had none so pump next logical thing. :twisted:

Post by **Punchy** » Mon Aug 04, 2003 4:55 pm

yeah i was sitting here thinking about those issues you had there.
I have the same truck 1hdt 80, and mines still running swheet

Now the 1hdt's had a small issue with surging. This was a factory toyota flaw and toyota were doing warranty repairs on the pumps for a number of years. Depending on how old yours is it may be eligible. It can be remedied after market but alot off pooftas in injector shops want anything up to 800 - 900 dollars to make the modiification to the pump..
Someone hinted to me that it was a simple mod thats done with the lift pump a this some how works the line supply pressure better to promote a smoother supply..
sounds logical...may be bogus.

I was sitting here and thinking that your truck was running lean..
Now this was for the fact of the white smoke. Diesles do make white smoke if they are running rich yes..but they can do it if the supply and timing is all wrong too..
I'm glad to see you covered all your bases with checking the injector belt timing as well. Old belt with a bit of stretch certainly wouldn't help.

Now if your injector were cracking off 400 psi early thats fair enough.
what happens here is you get a slightly noisier engine (because its tring to detonate with to earlier an ignition happening) but if its not happening to early..its going to make a heap more power..

Since having your injectors done, you may find a drop in power.
Two reasons.
The delayed timing now in the injection pulse cycle (not cracking off early- thus means it shuts sooner too) which means its getting less fuel now.
Secondly, the diesle pump is now having to work a little harder as the injectors are cracking off as easy and the extra presure helps with bypass in the pump and head if theres a little wear..

This is all remedied with the pump rebuild or tweak..
Don't expect to get away with it two cheap..

Average 1HDT pump rebuild STARTS at 1600-1700
and with the surge mod may cost up to 2500...just for the pump..and that doesn't include fitting.

YOu also mentioned that you had your nozzles done for a bit over 540 $
One question..
Did they fit Genuine Nippon Denso injector tips...I bet they didn't.
The after market units don't return as long as service life as the genuine units.

But i'm intersted to find out how it all goes for you

The units they showed me that they were fitting were in genuine nippon denso packaging and they told me that they were.

hmmm

It just sounds a bit suss...
I just cant help thinking someone is taking a lend of someone because everyone i spoke to in brisbane in regards to servicing the injectors with ND tips and so on wanted at least 880 minimum to do them..the most i got quoted was 1100.

I would assume that the guys in brisbane are either touching people up or someone got a real good deal..

lucky you

i just got the news on my pump and it anit good. i have damaged (f**ked) the cold start mechinism at $1000 and cracked the case $1000 and broke a pin on the etcentric shaft to the extent that it was making metal and it went through the pump. at a approx cost of $2500 before even getting an overhaul. i am now looking for a second hand pump to suit a turbo desiel 92 model as it has the mod. if any got on pm me. thanks

Post by **macuserau** » Tue Aug 05, 2003 9:49 pm

back to the injectors i was told that the price of the injectors nozzles had been reduce considerably and that the $540 also included $150 labour to fit. the nozzle were about $360 ish and that the washer at the bottom of the injectors were about $35

Post by **Punchy** » Wed Aug 06, 2003 8:31 pm

dont stress ..

You can use an aspirated pump if things come to worst case scenario and you cant find one.

The main difference is that fact the turbo units have the boost compensator pod on them and no mechanical advance in the pump (so im told)

The aspirated unit can be modded and fitted with a bit of tweaking..and if you get one that needs modding anyways they should be able to fit the boost compensator if they are worth a pinch of salt..

good luck
