1990 TD27T, Cold start issue's
Hey guys
Popped around and collected my bro's 1990 Terrano (TD27T) to give it a clean and tidy up for him. It was really quite hard to start after sitting over night, turned over heaps and even with the chock out full it would slowly die down and stall. Once I got it down onto the flat it was much better but still I stalled while driving 3 times in 10 mins until I finally decided to just sit in it & wait for some time. After another 5 mins just sitting it was fine, perfect even. After cleaning it I started it again it it jumped to life straight away no probelm.
I've been told to check the fuel lines to make sure there isn't any air getting in (splits etc.) and Im also wondering about the glo plugs??
What could be causing it to struggle when cold?? Any idea's what we can do to sort it?? Im new to diesels so could use some help smile.gif

Cold Start
The first thing I would do is to have a battery test done then once this has been checked out look at other things. Mine bursts into life after using the glow plugs for a few seconds on cold winter mornings. Next step would be to check fuel lines or could even be as simple as changing a fuel or air filter .

Hey guys
Will have a check of the battery 1st.......would be great if it's that simple
It definitly has something to do with sleeping on a slope for a period of time though as for a couple of nights he left it down on the flat part of the driveway & the next morning on both occasions it was far easier to start & once going didn't stall.
Any idea what releated to the level of the vehicle might cause this sort of issue??

Hey guy's....been a while since I posted so I thought I'd update. Well after it got so bad it could only drive 500 metres then completly stal (and on my way to get it looked at the skid plate fell off at the front & I couldn't take off one of the nuts holding it on the back) oh & the front left shouck stripped off the nut at the top so that was banging around in there he left it home up the drive way for about 3 months. I told him to start saving up some $ & I'll get some of my mates to hook him up some cheap repairs.
I had a friend go around to take a look at it...he went over the motor checking everything & came to the conclusion that the fuel pressure was low & the fuel pump really needed to be looked at. He checked the glow plugs & noted that the peice...not sure exactly what that sits over them was not on properly so also clipped it back on as it should be.
About 2 weeks ago he called me to say that he tried using it again & it's running great!! I went & picked it up & have had it with me till last night. No choke needed & it starts 1st time everytime even after sitting in the cold all night...pretty much back to normal! It's driving fine & although it has what looks like a big oil leak it's not actually going through the oil. I scored & replacement shock off trademe for $50 & had that fitted so that's all back to normal, had a wheel alignment & balance so it's much smoother, although he noted the front left whell is a little bit buckled & the tyre's were all a bit buggerd so he couldn't balance them 100%...also there was to much air in the tyres!
I got them to remove the skid plate & he can get it fitted with some brackets at a later date. Now however it seems the fuel pressure is to high, when you 1st start the vehicle it blows a lot of black smoke....after driving for 5-10 mins it settles down and only really blows a tad if you boost it hard. The guys mentioned the fuel pressure is now to high...the smoke is not oil it's fuel, he said there is to much fuel being pushed through the lines so when it's started that's why it's blowing so much smoke. So for some reason the fuel pressure is changing by itself....I assume I really need to get the fuel pump looked at yeah?
I wonder if it's just easier to get a replacement one of trademe? i have a replacement turbo coming over in my car from japan so that will hopefully sort the issue with il blowing through the turbo.

You will get lots of black smoke untill the engine reaches opperating temp.
There is no Fuel Pressure as such in a Diesel like the TD27. The fuel is drawn from the tank to the injectorr pump, by the injector pump. The pump then meters out the fuel required for the throttle position at the time and sends it to the injector. The injector has a burst pressure of around 120psi. when the pressure in the line from the pump to that particular injector reaches that burst point, the injector opens and releases the pressure in the line by injecting fuel into the combustion chamber.
When the pump and injectors get tired, the opperating presures drop you get a sluggish smoky vehicle.
It can't pump to much or two little, its all mechanically controlled by your foot and the timing gear. There is no pressure settings that can be adjusted other than by setting up the injectors which requires removal and specialist equipment and expertise.
On that note an airleak between the the pump and the fuel tank will create all sorts of drama!!!!
The build up of oil after the Turbo is Blow-by oil from the crankcase and is normal on all vehicles to varying degrees depending on the condition of the engine. A new Turbo will not fix this.
I think it was mearly your glow plugs............

Ah ok....thanks for clearing those things up
It seems to be performing well now......do you thing it is worth looking at new injectors or pump? or new injectors & 2nd hand pump?
What about running some injector cleaner or stop smoke type syuff through the system?? Would any of those treatment additives help do you think?
The fact it is running so well now would probably mean this isn't an issue now yeah?
It's blowing through quite a bit.......with the pipes off after the turbo & the motor running you can see a pretty steady stream coming through, it's leaking out of what I think is the actuator & being blown all over the firewall from the fan etc. I wouldn't have thought it would be so much. Does the turbo not have seals that can go??
Seems like it aye
bit of a relief really.......just still not sure it should be so smokey....would like to try & get ride of so much if it's not to expensive for him.

New Injectors and recond pump. Bit pricey though How many K's has it done,you should only need to get the injectors done. Injectors (new) are around $60 each plus labour for setting up properly and fitting usually.
Try some moreys injector cleaner/fuel conditioner.

Would say so.......

Hmmm, do you mean a steady stream of liquid oil??
Blow-by is a hazey steamy looking discharge consisting of oil vapour and gasses that have leaked past the piston rings during combustion. It is not a liquid. The pressure in from the turbo fources the oil out of the vapour much like in the crankcase of a two stroke engine, hence the oil build up in the pipes after the turbo. To look at the blowby remove the breather hose from the back lefthand side of the rocker cover.
If you have liquid oil flowing out of the turbo while the engines running, then yeah, you have bigger issues!!!!

Yep...a slow but steady stream of liquid oil.

I really wouldn't trust the km's but it say's 140,000...is a 1990.

Cool...will definitly try running some of that through.

Well in that case you definatly on the right track with a new Turbo. Replace that and clean out the intake manifold as best as you can. Chances are your smoke will stop once that stream of oil has been delt with!!!!!
If not, then look at the injectors, the pump should be sweet, 250,000K's it might be getting a bit tired, but not at 140,000.
That stream of oil will definatly be producing a shit load of smoke, especially after idling for a while.
