I had a friend running on bio diesel and at one point he lost lots of power and his injection pump was ticking. he changed his fuel filter and all was tickaty boo. You have allready done this obviously but it sounds like something else, tank pick up/ pipes or something is blocked. To check the lift pump is working properly you can remove the power wire to the injection pump, disconnect the fuel pipe from the fuel filter and crank the engine over. Cover the pipe with a towel or something. If its working there should be lots of fuel sprayed everywhere. This could indicate if the tank pick up or pipes are blocked

I run without an oil cooler with no probs but if you are concearned simply plumb a small one in the engine bay(saves a load of pipework), also if running a rad in the rear you are better off not useing a tdi rad and going for something larger like a v8 one which is a full lenght jobby which is going to give you far more cooling efficiency as you will need as much as you can get due to restricted airflow, i'm currently running a ali freelander one as it saves a fair bit of weight if that's an issue for you, good luck with it
that wont be a problem. were using a tdi rad. there hugely overcooled anyway, there is gonna be so much water in the system as well. I think we will just leave the oil cooler plumbed into the back, its there now.....

Std oil circuit is.
Sump, oil pump, filter, cooler(if hot enough), engine brgs, sump.
so your saying that the oil goes through the cooler before it goes through the engine? so its in the high pressure side? and having the oil cooler in the rear could cause oil pressure problems?
-
FWIW, a friend has been building a challenge truck with a 300tdi and a rear rad, and he's using the built in oil cooler.
It has no problems at all getting, or maintaining, oil pressure. The radiator is on the low pressure (after the engine) side of the circuit, and isn't even in circuit all the time - the oil thermostate means the radiator is only in circuit when the oil is hot enough.
Thats good to hear. thanks for the response
And oil doesn't compress very much at all, so getting pressure generally shouldn't be a problem anyway, but you may find oil changes are a bit difficult; either the oil comes out and it takes an age to refill ('cause now it's full of air) or it doesn't drain and you have a load of dirty oil left.Having remote drain & fill points seems extreme but I can't think of another solution to that one. How would you get the oil after it had been in the engine, as normally it just drips back to the sump?

thats isnt too much of a problem, its not a road going vehicle so it can be left to drain. I dont think we will worry about dirty oil being left in the pipes. we can move them about to help with the oil pipes around a bit to help it drain.
I have a 80 200tdi with rear radiator! i will watch this with interest!!
You say you are gonna watch this.... If you have one how long have you had it? what do you do with it? any had any problems?
Also does anyone know if the 200 has a thermostat for the engine oil as standard?
cheers

My dad and I have been building a 200tdi 80 inch trialler/possible winch vehicle from a disco 1.
We have put the radiator right at the very back and we have extended the oil cooling pipes for the engine to it.
It has been suggested that this may make it a very long time for the oil pressure to build up. Does anyone have any experience of this or knwo the how the oil circulates around the engine?
I would have throught that engine oil would be picked up from the sump (obviously) and then used to lubricate the engine which would then be put through the filter to take out any carp picked up by it and and put through the oil cooler when it is hottest and fed back into the sump. This would make me think that there would not be any oil pressure problems, but i could always be wrong.....
Basically I want to know if we are gonna bugger the engine?
Thanks for your help

also just to check, they are both 24 spline at the diff so is it possible to say use ashcroft shafts etc with a KAM diff?
cheers

i assumed it wasnt the mark evans one. i have that already. ibexman did put 90 in the title.....

anyway of getting it apart from discovery?

The smoke is white by the way so unburned diesel.
as steve b said. black sooty smoke is unburnt diesel.
blue smoke is oil
and white smoke is either your burning water or a big air lock in the fuel system i believe....

check the injection pump end of the accelerator cable. mine became loose at one point and did not want to tick over or start very well. I adjusted that and it started much better. but idled a bit high. but my injection pump was also starting to die. it might help....

I know its more expensive but me and my dad got our radiators recored by Kempston Radiators near bedford with an "off road" core. Its a lot stronger has bigger gaps and is pressure washable ( Supposedly without falling to peices) but we havent got them properly caked in mud yet. After a long drive my raiator is completely cold at the bottom and hot at the top.
They are just a little under £200 quid though.
-
Just wanted to say PM me with a price if you are thinking of getting rid of any. thats if they are for a V8 defender.
cheers

Only when you are moving slowly. I think 10/15 mph may be the limit but i am not certain. You should put the gbox in neutral first as well
Im sure an adult will come along with the exact procedure
-
I've got a Durite gauge fitted. That steadies at about 82c,with the top of the rad.
hot same as yours. The thermostat doesn't open with a bang, so perhaps 88c is when
it's fully open?
that would make sense actually. good thinking
I hadnt thought of that as with the old land rover gauge it used to spike and then level off. So i was just assuming the thermostat was open or shut.
cheers

I have never had to change the thermostat and its probably not worth disturbing it unless it fails. so maybe ill just leave it.
Anybody have a VDO gauge and that knows what temp there thermostat opens at? and knows what the gauge reads?
-
Hi
The other day i replaced me standard land rover water temp gauge with this gauge and this sender,
http://www.merlinmotorsport.co.uk/p6142/VDO-WATER-TEMPERATURE-GAUGE/product_info.html
I thought these would give a fairly accurate temperature reading, however on my 200tdi which has an 88 degree thermostat, when the engine is up to temperature the gauge reads about 82 degrees. At this point the top of the radiator is hot and the bottom cold. Since the top of the radiator is hot this must mean the thermostat has opened. So why doesnt my gauge read about 88? Has anyone seen this before? Are the gauges just not really that accurate?
Cheers

Maybe its time to crack in a v8 with lpg?
conversion should work out cheaper than putting in a TD5 and i beleive the v8's are LEZ compliant. and shouldt be any more on fuel
Just a suggestion....

everything should fit, but check the radius arms are the same width if you are changing them. They should be the same.
-
make sure the next one is a genuine seal. It should be fine..... Im not sure if your engine can leak oil from anywhere apart from the cam or crank shaft seals. Sure someone will correct me if I am wrong
-
are you sure it was the crankshaft oil seal leaking and not the Camshaft oil seal leaking? and did the new seal come in a blue box?
-
it was saying just a bit over 750 at idle which i beleive is correct and when the engine was reved it seemed to be going up at the right rate, didnt disproportionatly sky rocket at all so i believe it was working well
-
i dont beleive so
300Tdi won't rev

I am not sure if the lift pump will tick but the injection pump does tick if its trying to suck fuel but cant due to a blockage.
Make sure you use a genuine lift pump. When you change the fuel filter and lift pump did you have any problems bleeding the system?
If it takes a while for fuel to come out the bleed screw it could be the lift pump as, AFAIK it should be supplying more than enough fuel for the injection pump at any revs. But this also makes it sound like air could be getting in the system.
