I know this has been asked a few times, but still trying to find the spot on answer.

My 95 D21 Terrano has some starting issues.

Only happens in the mornings or once its been left for more than say 8 hours.

As soon as i start it up it will start to miss, then stall unless i give it some gas, and at that point a heap of white smoke pours out. Then i have to rev it for a couple of mins (not high tho) until it stops smoking (or drive without stopping for a bit). Then all is fine?

I'm not 100% sure what it could be, a diesel mechanic said over the phone it could be the injector pump seal as air might be getting into it.

I flick the ignition on a few times incase its the glow plugs not working properly but that doesnt seem to do anything.

Not really good at diesels as this is my first!

any help would be appreciated!

thanks

Fars i have a simpiflyed version of the workshop manual here that may b of help if you want a copy pm me with your e mail addy and i will send it to you

Isn't white smoke associated with water?

Isn't white smoke associated with water?

Yep!

Hmmm hope its not expensive, taking it to a mechanic this week sometime to check over.

Will let you's know what the outcome is

So it only does it when the motor is cold and as soon as the motor has some warmth to it it runs fine? And it starts no problem if the motor is warm. Also the problem has only started with the cold weather?

Have you had the glow plugs tested? Sounds simpilar to a TD42 I had and that was a dead glow plug. Hard to pick up as it started easy because all the other cylinders were fine. The smoke isn't black (as you would expect from excess fuel in a deisel) as the cylinder isn't burning at all.

So my guess is one glow plug has failed.

It could be an air leak (or anything to do with fuel) but start with glow plugs as any manual should be able to tell you how to test them yourself. Injector pump gets expensive quick so test that last.

Hey bro my mates pajero does the same thing when cold. he did new glow plugs and made no difference he was then told by a mechanic its something to do with either oil or water getting somewhere in the motor and it needs to burn it before it fires properly (not headgasket) and they said that he might need to replace the rings as its done high kms and they might be a little worn and when sitting it seaps through.

Nah it did it over the summer too. Even if it had been sitting outside in the sun all day and i go to start it at night its rough. Will check the glow plugs though, cheers!

Hey Ray. That could be the problem. Mines done 195k so its not majorly high. But will definatley check the rings too

cheers man

Farrk, why do people come on here and ask questions, get advice from people, then a month or so later come back on and say they are still having problems when they haven't even followed any of the advice given.


Its your glow plugs.

Go and replace them.

Problem solved.

Summer or winter, it will cough and splutter on cold start up if the glow plugs are knackered.

I'm with you Dieselboy, That's why I don't bother answering many questions any more. . Your symptoms are typical of faulty GLOW PLUGS , and you need the 4 of them to work to get the right resistance. Diesels especially older indirect injection ( like yours that inject into a pre combustion chamber ) models like yours need assistance to start, once running they will soon generate enough compression heat to ignite the diesel. Even late model common rail direct injection models still have a ECU controlled inlet manifold heater that cycles long after start up until operating temperature is reached. Pure white smoke is normally associated with water in the combustion ---- but whitish grey and blue is cold unburnt fuel caused by NOT ENOUGH HEAT. I would say that your old diesel has got many a Km left in it if it is running OK when up to temperature, these old TD27's are pretty bulletproof ( oops sorry BULLETPROOF ).

DO IT,

Thank You! I will check the plugs tonight. Appreciate you making me understand.

While I'm on the key board I will advise members of a problem that we have struck at work , we run a fleet of small Diesel Utes, Mazda's/Ford, Nissan's & Toyota's, we have had trouble with the Nissan and Mazda/Ford hard starting and no power, after many hours of fault tracing and even a pump sent to be overhauled because someone thought the governor had packed up we discovered ( the overhaul experts didn't find it ) a very fine gauze filter at the fuel entry to the pump, remove the fuel pipe to the injector pump, using a sharp pointer ( scribe,sharpened nail ) ease the filter that is in the body of the pump out, being careful not to damage it, clean , refit, bleed system and you will be surprised.

Yep, done that to my pig fitzy, big difference in power.

Hi There,
I know what you mean, my Mazda 2.5 eats glow plugs, (up to 3rd set in 5 years!). With the TD 27, the power to the glow plugs go through the manifold heater, hence why when 1 or 2 glow plugs are faulty, the whole cold start system turns to shyt.
Great tip on the gauze.
Cheers,
Simon.
