on saturday the guy from work pulled the head of prado 03 model with 88000ks.
2 big cracks in the head.
this is the second low k prado(other was 110000ks) we have had in the last 2 months suffering the same problem.
both of theese prados had after market chip upgrades fitted.
the first one we thought nothing of the chip but to have both with chips and cracked heads seems a little suss.
cheers

What people seems never understand that it is impossible to have something for nothing. With “unleashed” engine power situation (turbo, chip, gas anything) extra power can only came from increased pressure inside cylinders, does not matter by what means it been achieved. It equals more stress on everything. Thus less longevity and reliability. Whatever you do just remember this fact.
Side conclusion – modern fully-computer-design engines actually less robust then older ones, as least because older engines were far more over-engineered.

To add to your conclusion the whole vehicle these days is far less robust, they aren't even engineered to cope with designed loads never mind overloading or expecting the vehicle to perform its role continuously!

Its all consumer driven.
Everyone wants a vehicle with more power, less fuel consumption,seats 8 people,can cross great deserts without stopping and overtake roadtrains with ease.
It goes without saying that it has to have PS ,power windows and chilly aircon.
And when the owner goes on holidays its got to have a bullbar ,loaded roof rack and 2 spares on the rear.
If you dont want the headaches with computers and alloy heads,buy a old landcruiser and learn to maintain it yourself.

Yep, cast iron probably not the lightest material around but indeed most trustable. One day I have noticed that temperature gauge in my 60 diesel LC climbed almost to red zone. Never happens before. I have open bonnet and cool it a bit to be able to drive home. At home I have discovered that about 10L of coolant escaped via hole in radiator! Soldered hole, add coolant and it was end of story. Could alloy head survive this? Dream on!

Sorry to break the news KSV but the 2h heat was quite prone to cracking when overheated. Certainly
mine did and others ive talked to have had it happen. my mechanic when diagnosing the fault did some ringing around and found it was the most likely culprit as it happens often.
almost to the red isnt overheating which it would have done if it lost 10l which is all it takes

I have not said it is impossible – any head will crack if good enough temperature applies, but rather recon it is much easier to damage alloy head. AFAIK loosing almost all coolant in allow-head engine definitely spell doom to head, while cast iron can survive.
Mine did, and served me for another 3 years until sold.

TROLL.
Any fool knows Toyotas never break down.
Next you'll be telling us you heard of an Engel fridge that stopped working.

I thought the Prado TD before the latest model was just the low tech TD out of the hilux with an intercooler. These things run all mechanical injection so wouldnt take a chip?
maybe not?
