TD5 Failure.
The oil cooler failed, apparently the core corrodes thin and when they rupture the oil and coolant mix. The engine quickly overheats as the coolant is transformed into an emulsified sludge. The combination of dropping oil pressure, contaminated oil and rising temperatures ensured this engine will never run again.
Apparently there can be some early indications of this impending failure such as droplets of oil in the radiator expansion
tank.
To qualify the oil cooler it needs to be removed for an internal inspection and considering the failure outcome it may be better to select an interval and replace it. The vehicle a Defender is 7 years old and traveled 170,000 klm.
Hope this info helps others from learning the hard way.
Regards

On the AULRO
forum there have been a couple mentioned. I think $4.5k for a genuine complete head. A friend of
mine has had two Toyota heads done in the last few years. One H and one 2H and both cost $4k for genuine replacements.

What would it cost if you only gave it a No.1 head job

The price was actually $7-8K but that included 5 injectors @ over $1k each. Later heads came without the injectors and glow plugs.

Thanks for the warning.
Even thought I have a Pajero 2.8 ITD, it also has the oil cooler mounted in the block in the
water jacket. Same thing could happen. The older 2.5 diesels had the oil cooler externally mounted up near the radiator. Advantagesand disadvantages.
Makes you wonder how important it is to use the right corrosion inhibitor in the
water.
Any thoughts about what you used?
Will keep checking the radiator by taking off the cap and if I see oil on the top, will be very suspicious.
Thanks - this problem had not occured to me before now.

Getting a little paranoid in my old age, and the old age of the engine.
Got almost 300,000k up now. So thinking of what can go wrong in the next 100,000k. Haven't touched anything in that time except for normal servicing.
The oil cooler leaking into the
water jacket never occured to me.

I view dealerships with suspicion since the local stripped my wheel nuts and I needed a four foot bar to remove them.
I use the recommended coolant and change it every forty thou or so using demineralized
water.

one of the biggest issue i thought was the regular changing of the timming belt (70,000km) if you go any longer you are very very brave, i thought this was the cause of most of the engine failures.

That's the 300Tdi motor which is the engine in the model before the Td5.

Spinifex.
Did the td5 have a copper heat exchanger for a shower? Eric.

Hi Eric.
I see you point, (dissimilar metals) but no galvanic corrosion going on here.

Sounds like its time for a GEN III or a 6.5 GM.
Both half the price (installed) of a new TD5 head by Truckies calcuations

There's a variety of "failure indicators" here depending on whether the oil goes through the radiator tubes or through the cooler radiator tank. I would say on most engines the oil would go through the tubes as it's easier to maintain the oil pressure that way. SO if a tube was slowly failing, you'd get a drop in oil level on the dipstick and signs of oil in the engine cooling water. This is based on the oil pressure being higher than the water jacket pressure so the oil goes into the water. Theoretically this should have been picked up long before there was such a catastrophic failure.
If a tube did blow suddenly & catastrophically, the oil pressure would drop very rapidly and the oil pressure warning light or alarm would come on. Stop engine immediately!!
Someone's not been checking things,,,,,,,,
Whose car was it Spinifex? Not yours I hope!

Hi Bilbo
As you say, if it is a weeping oil cooler you can be lucky and pick it up early but if it ruptures on route then the demise is swift and merciless, by the time you notice anything amiss the damage is done.
You know the old saying if your oil light comes on at highway speeds then it is a bit too late.
Not just head damaged, cylinders scored as
well.
The repair
shop has another TD5 in it that had done the same thing.

So.......that's 2 of how many TD5's on the road,
Compare it with the number of blown Nissan 3 litre Patrols listed on this
forum since 1999.
It would be interesting to
check on the various Nissan,Toyota and Landrover sites as
well to compare numbers of stuffed motors reported per make.

Thats about right, there would be about 2 TD5'S on the road. The rest on tow trucks, or in the
shop!!!
