Has not broken ANYTHING in the driveline. Pretty reliable I think, and cheaper to run on gas than even a 200 TDI at the moment.

cheers, DL

Until you start towing or playing in soft sand :angel:

Hi CE,

You must be talking about $$$$ rather than breaking things. You're right if that is the case, comparing my POS with a 200TDI. Gas consumption rises pretty quickly when towing 4 tonnes, but nothing broke in the driveline. I don't tow a lot of stuff very often.

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

I own or have owned and driven, 3.5 V8 auto RRC, 4.2 V8 County and I recently bought a '99 Td5 Defender, but for me, my Isuzu 4BD1Turbo in the County out shines them all. The Rangie is comfortable, but simply guttless for the amount of fuel it uses. The 4.2 in the County was a fantastic motor, plenty of go on the road and excellent torque down low off road, but used too much fuel also. I've only had the Td5 a few weeks, and I must admit I am impressed with the on road power it has for a little 2.5 litre motor (even if you do have to rev the crap out of it) and the fuel economy, but it lacks torque.
The 3.9 litre Isuzu Turbo (intercooled) would give my 4.2 V8 a run for it's money on the road and as good as the 4.2 was off road, the Isuzu is better.
Compared to the Td5, and regardless of it's apparent reputation as a 'harsh' motor, the Isuzu is more relaxing to drive, and you don't have to ring it's neck having an abundance of torque along with great fuel economy. And with 500,000 kms + between rebuilds (and that's when they've pulled 7 tons GVM all day, every day) it's cubic inches and no electronic crap for me.

Say whatever you like but a daily driver that has 500k on it is a donkey.Don't let the big miles that trucks run up fool you into thinking all of them do it easily and how many times have any of you done that many k's anyway,probably none and that motor will cost more than you will want to spend come rebuild time.

LR on the other hand had a good car but needed propulsion and used the quickest and cheapest way to get this. In the end most of LR's engines are substandard but they did come up with the odd class leaders when they tried. The 3.5L v8 was shoved in everything they made for 30 odd years unlike bmw who make a new engine for every new car (just about)

These engines do go the distance. I've heard of more than a few that have 350,000 to 500,000 + on them and I've spoken to a couple of guys with more than 750,000 on the clock......all of them in Landys and all still going strong.

As for rebuilding costs, I have the receipt for the FULL rebuild on my 4BD1T. $6202 including rebuilding the injector pump and retipping the injectors, even removing and refitting the engine to the vehicle. Look up the list price for a Td5 injector, 5 of them will cost you more than my full rebuild. I even know of an injector pump from a 2.25L Landy diesel that cost $1200+ to rebuild.

Cheers, Murray

I have gotta say that I am one who has done 750k on an aftermarket turboed Isuzu 4BD1 and it cost virtually nothing in maintenance - replaced a couple of seals and had the injectors cleaned twice - both times they didnt need it apparently. Eventually it lost compression due to worn out compression rings but was still running pretty good just lacking power on hill climbs and accelleration. When it came time to rebuild I looked around and found a complete genuine replacement motor for $3500. I would't say that was an arm an a leg. AAAND it gave excellent fuel economy......
I have also had a S111 that I converted to 351 Ford cleveland V8 with C4 auto. Now that was a magnificient machine. I put the earlier series low range transfer gears in (lower gearing), rangie front axle (with leaf spring mods) and extensions on my rear Salisbury axle to match the RR front track (made by Mal Story) and 3.54 diffs. Surprised many a toyo/****in nissan driver. I had a maxi locker in the rear and offroad/in sand hardly ever had to get in 4WD. The auto did all the work with the big cubes effortlessly pushing it. Was a bit heavy on fuel around 15mpg but that was in the days when fuel was cheaper and it didnt matter that much. The transfer box axles chassis etc all handled the extra grunt without any problems. Got a couple of pics somewhere if anyone wants to look at it....Bearman
