Hi Edd
From the posts that are coming up,it seems the problems are normal,updated ECU/intercooler or not.
Its a worry

Agreed....

Got me beat....

Why is everyone so worried????

Well because I spent 4 months of my lease fuel money all my maintenance budget and $4000 on my rig this year! I also still have 21,400 km to go on my estimates to reach the target. I'm going to have to organise a state deck or pay the excess FBT to keep my baby. I know I can't afford this level of repaires on top of what I had to spend on the better halfs car.

I guess that considering the age and the kms, the possibility of the gasket going is increasing and the cost and inconvenience of having to replace it en-route, its much better to start afresh for the long trip.

I was going to check the tension of the head bolts on mine (only 100k) as head bolts generally tend to loosen (stretch maybe?) towards the back of the motor, possibly due to poorer coolant circulation. But I've decided to not touch it unless the engine gets overheated in some way (eg blows a radiator hose).

some possable reasons to consider a replacement head gasket as preventative maintenace are.


1. Engine over heated
2. contaminated coolant
3. contaminated oil
4. when torque checking head bolts you find a loose one
5. full cooling system flushout produces any kind of non oxisized materail
6. At the age/hour on the engine when a lot of other engines of same type/breed have had head problems (tho youd be replaceing it cause youve pulled the head)

The TD5 is pretty much a universal engine, it's used on every continent of the globe in some very ordinary conditions. Obviously by the fact it has a fairly small turbo, and the fact it can be flash tuned to get such decent Horsepower increases tells me it has been detuned for engine driveline and gearbox longtivity, fuel economy etc..


These are not racetuned engines and should not need a rebuild at such low kilometres

Hi guys,

I've got 230 000 on the clock now.
1999 TD5 Discovery.
Whats been brewing under the bonnet.
Radiator, replaced this just before the trip around aus as a precaution.
Replaces a few soft water pipes.
Engine harness has been replaces.
Turbo pipe, the LR dealer in Wollongong stripped and broke it.
Fuel pump ( i think) just behind the engine.
Manifold, broke 3 bolts just the other day.
The fuel cooler leaked water twice and then never again, I replaced it with a second hand one ($20).
All of the above was picked up in time. I try my best to look after the car as best I can, average service interval is around 12k not 20k.

Ps. Many thanks to great servicing from Frank at ATV land rover.

Cheers

Hi All
We have just over 100,000 on the disco with the only problem being oil in the harness which i have the looms on the way. I was told it was a good idea to try to oil proof the back of the plug that is in the head as even some of the new looms still leak one suggestion was to seal it with sensor safe silicon which i will look at when they arrive. Would love to do the chip upgrade soon.
Regards
Doug
