Haven't noticed any big gas consumption probs driving in sand. Maybe there would be if you had a 350 up front and were running the stock razor blade tyres, I don't know.

cheers, DL

Yeah I was talking about $$$$. I wasn't talking about breaking things.

One of the advantages I find with the 200 is when towing (or even soft sand etc) the fuel consumption does not go up much at all, compared to a petrol engine.

I remember a couple of years ago, we went from Birdsville to Mt Dare on the one standard tank. I had the jerry cans but I didn't need to use them. Every other vehicle in the convoy used for fuel than us by a lot. The two pertol Landcruisers nearly doubled our fuel consumption.

You've got me interested in the V8 idea now you bugger

Cheers
Chris

Hi all,

Just wondering ... how come diesel engines are so incredibly expensive compared to petrol engines?

The question is not diesel vs petrol so much anymore, rather new engines vs old. New engine parts seem to cost so much money that it makes old engines (both petrol or diesel) look cheap. In a common mazda engine O2 sensor through mazda they quoted me $500. Thats not cheap but its a modern petrol engine. Go any euro cars and triple that price.

Now I'm just confused!

So rididij your telling me you fully rebuilt your engine,from lift out,machined block,reco head,reco turbo,reco injector pump,pistons,rings,bearings seals and refitted for 6 grand?.The Tojo T/D 6 have a common fault were they break cranks and I cannot rebuild one for a price that makes it worthwhile,I can buy crate engines for 10 grand so your price is cheap to the point of unreal.

Well that just proves how over-rated and over-priced Toyota stuff is. Not that I think Toyota make a crap product, they don't, they just brainwash their customers into thinking they have 'the best' because of their massive advertising budget. The managing director of Land Rover Aust told our club that Toyota's advertising budget for the Kluger alone was equivilent to his budget for the whole Land Rover range for a year.

You can buy a basic rebuild kit for an Isuzu 4BD1/T for under $1300 see here >>>> (Isuzu 4BD1)
The thing is, the Isuzu engine is a simple, tough donk and was made with rebuilding in mind as it's VERY widely used in trucks and industrial applications throughout the world.
Speaking of cranks, the 'Tufftrided' crank in the 4BD1T is so hard you can't even machine it. And a lot of the parts are rebuildable and not 'throw-away' items. It might be a Jap engine, but it wasn't initially aimed at domestic vehicles, so being a commercial engine, you should expect it to be cheaper to rebuild to fit in with commercial economics.
My receipt (from 'Head Torque' in Melbourne) doesn't mention the turbo, but I expect they checked it out. But even without a turbo rebuild, 6 grand is quite realistic IMHO.

Thats not an uncommon state for materials be it through tuftriding or heat treatment. Files and centrepunches are other examples of parts that cant be machines as they are. The reason the whole crank is like that is because of the tufftriding process where it isn't a localised process, but it is a very thin hard layer - which has benefits too.
