When letting engine idle while turbo cools down, how do you know when it is cool? I remember about 30 something years ago, when saab were introducing turbo petrol engines to rallying, seeing a picture of one getting bench tested. It was glowing yellow.
Its not the cooling down thats the problem its the lubrication to the bearings as they run at high speed when working. If you just switch off then the lube to the bearings stops working. So a minute is usally enough so thta the turbo is running at low revs.
Nothing to do with turbos, but a cheap, and reliable 4x4 is the Toyota Surf 3 Litre. Keep away from the 2.4, unless it has a new head on it.
There is one on Autotrader at the moment for £2,800.
1997, top of the range spec with 97,000 miles.
Could be worth a look if it is local.
Cheers,
Jim.

That could be why some turbos are prone to failure if not idled on shutdown and others are more tolerant. It seems some have ballbearings and some use journal bearings, and some have watercolled bearings. If you have the ballbearing type then they can manage with less oil ( allegedly ).
Well we just got back from Ferry Meadows and when we arrived the pitches and roads around the pitches were still covered in snow and packed ice. So much for hard standing.
We were pleased (again) with the Pajero, as we wound our way round other cars struggling to get on and off their perfectly flat pitches.
Though we were a bit surprised no grit had been used?
Been towing with Range Rovers for many years with almost no problem, as mentioned output shaft wear can be a problem on earlier models and after high miles, Land Rover modifield the problem part and reduced the problem significantly.
Tried a jeep Cherokee last year, good towcar but a little short of room inside.
Condition of your 4x4 is all important so find the best you can, low miles, service records, etc.
For the last 3 yrs Ive been towing my van with a 4.5 litre Cayenne whilst it has a serious drink problem but makes my life a hell of a lot easier.Ive just bought the wife a Shogun Warrior 3.2DID so will be using that for towing and will let you know how I get on.
We have just gone from a 4.4 litre petrol Chevvy to a 3.2 diesel Shogun Field, not towed with it yet but the difference in fuel consumption is quite something.
I have a Jeep Grand Cherokee 2.7CRD (Mercedes engine). Tows a treat and does not cost the earth to run as an every day vehicle. The auto box is silky smooth and basically does what it says on the tin.
------------- Albino, Can"t say fairer than that !
Best to forget the older Discoveries: 200 series and 300 series.
Gutless and prone to corrosion (Land Rover never learned not to put aluminium and steel side by side in wet places)
We now have a TD5, which is supreme, but in demand strangely, due to reliability and ability.
Even my local garage calls it a reliable vehicle: its only weakness now is the fuel filter behind the rear-wheel...at least its visible and accessible.
we have a td5 it,s great it pull,s a twin axle no problems doesn,t cost much in diesel either don,t know what people are moaning about. we are very satisfied

I have a 300 tdi and its far from gutless and a great tow car I recall traveling to Cornwall with friends 1 in a Disco II and 1 in a 3.5 V6 Shogun
As we pulled out of a services to climb a long long hill the Shogun and I set them away and the Series II TD5 couldn't keep up with us at all
I know what you are on about with the rust but lucky me mine had a 9 years hoilday in Japan so has no rust and gets a thick coat of waxoil every 2 years

I'll never grow up!!!
