How many km have you done

[OLR-067]

Just to give me some idea of what might go, what I should look at, and what to expect in future...

How many km has your truck done and what repairs have you carried out. Not talking about general service stuff, but the more typical failures.

My truck has 410K, doesn't drop or use oil, but thinking of a rebuild on lt95, has had T/c rebuild, (previous) a new 70amp alternator(me) new rear brakes(me).At moment looking to sort some wiring stuff out......no doubt it has had more from previous owner but that's what I know of....

cheers

G'day Paul,

My 'zuzu started life in a 1988 110, bought new by my uncle and cared for up to 420,000km, when after his 110 rusted away around the engine, he sold it to me. I then fitted it with a turbo and intercooler to my 1992 RR classic, it has now covered altogether about 460,000km and is going very well. about 28 to 30 mpg, no oil consumption between changes(5000km) and until the original waterpump started leaking last week, no water consumption.
I fitted it originally to a ZF auto, the engine then destroyed 3 of these before I fitted a LT95 and haven't looked back.

I find it quite quiet on the highway, and has very little roughness at idle.

It has enabled me to justify keeping the RR, as the 4.6 was over the top for fuel consumption, I have almost the same amount of torque available from about half the revs, and uses less than half the fuel.:):D:):D

Expect these engines if looked after to last 600,000 to 800,000 km.They do in trucks.

what are ya doin mark...get back over that fence...:p:D

[sclarke]

330k from a 300tdi
Big end bearings (not needed, but done as insurance)

Thats it...

1986 County wagon.

Last service was 440,000km. Uses about a litre in 10,000km, mostly leakage. I think most of this is from the sump gasket, and I have one to fit.

Only work done on the engine - three thermostats, starter overhaul (return spring broke) and four sets of solenoid contacts, alternator rebuild, cracked o-ring on the external line to the oil cooler (boy, was that messy! - but it will help stop rust), injectors checked at 120,000km.

Apart from that, transfer case repaired, replacing intermediate gear and centre diff thrust washers; main gearbox overhaul prompted by noisy front bearing, new clutch at that time; steering box replaced at 160,000km, now have another new one to fit; replaced hazard light and instrument/interior switches plus the panel they are in; replaced instrument cluster moulding; replaced fuel tank; replaced seat foams; replaced grille; replaced headlights; Hose from air intake to aircleaner replaced twice; heater recored;

"Service replacements" - springs once, just got my third set of shockers, one set of pads, shoes, cylinders, discs, drums at 150,000 - all still good; handbrake shoes, assorted seals, tie rod ends etc; steering damper; one rear axle ball joint, all bushes, several times for the lower links at the back and the panhard rod; just got the second sway bar link to replace; two windscreens; one wheel; all blinkers, tail and clearance lenses - several times; hose from intake manifold to air cleaner pipe replaced; two mufflers; front door seals; vent seals

Routine service - all the usual oils, filters, wiper blades, tyres etc.

Damage repaired:- RH front corner (twice); LH front door - fire truck backed into it while it was being used as the brigade captain's vehicle; Back door - I backed into a tree; rear window replaced;

Extras fitted;- 60 litre auxilliary belly fuel tank; sill water tank; folding side steps; bullbar; air conditioning; central locking; driving lights; cruise control; child restraint anchorages; headlight relays; UHF; extra speakers;

Probably missed something!

comprehensive list John!!

crikey by now your radiator hoses must be a bit dodgy ? :)

Ok now that youve got it run in and its got a couple of teething problems.............................

I said I probably missed something! - radiator hoses replaced twice, just replaced radiator cap.

[andrew e]

mine has 440k on the clock now. Ive only had it since 330k. Replaced 1 thermostat, starter solonoid+brushes (brushes were a pain to solder), the top thermostat cover as it was leaking around the thread, the aicleaner (it still had the origional marked 1986), the water trap, top hose (leaking through webbing in the middle of the hose). I think Thats it engine wise. The rest of the driveline has been replaced with a defender one, bar the rebuilt rangie gearbox.

Fella i know has a 85 county with the n/a 4bd1 and last time i spoke to him was 3 years ago and the 4bd1 had 1.3miliion k's on it and no major repairs just the usual stuff like routine maintanance :D:D:D

Mine is an 84 mod in a stage 1 with only 150 k on it so its got alot of k'sleft in it :D:D:D

[Larns]

It's not uncommon for the donks in the trucks to do more than a million km's. Most of the time they just service the fuel injection systems.

[Dougal]

Welcome to the longest ever first post.:)

My 4BD1T has had a long and terrible history.

Originally imported from japan as a used engine and gearbox with "approx" 100,000km. It had done soo many km that the original gearbox was toast.
It was fitted into an 85 rangie with a new Isuzu gearbox on the cheap. The genius of the man who did the conversion is obvious, but I imagine given a few thousand $ more to play with the result would have been soo much tidier.
Rangie had about 110,000km on the clock (dealer who sold it has since been struck off for winding back cars among other evil deeds).

The fueling had been increased and I suspect the rev limiter wound out too. The truck would do almost 160km/h, I found out later with the rev limiter set to 3600 that 145km/h is the limit.

The engine was stripped for balancing about a year later. The difference between conrod bigends was found to be 17g, needless to say the improvement in NVH was remarkable.
At the same time the fuel pump was reconditioned (also reset to factory spec) and rings, bearings and seals replaced.

A short while later the engine started spitting oil out the breather. A strip down revealed the valve stem seals (not original parts) had lifted, been hammered into pieces and fed the tension springs through the oil pump and all oil galleries.

What followed was a rebuild courtesy of the valve stem seal manufacturer. The block was bored out and cast iron sleeves installed (don't do this). Many parts bolted to the engine were reconditioned at the same time.

The vehicle then did about 40,000km of almost solely offroad work, then I inherited it. What was to be the start of a very intensive hobby.

I found and removed a tight restriction on the air intake to the turbo, noticing at the same time the turbo compressor wheel was eroded.
The result was a massive improvement in power, but the engine then again started blowing oil out the breather.
The source of evil this time was the air cleaner with elements which didn't seal.

Partial rebuild time. No time and no money so new rings were installed and away it went. The cast iron liners were noticably worn.

I found a new (old) turbo compressor wheel and threw it in. Boost went from 12psi to 17psi and took the headgasket with it (reused from last one).
Found that the turbo wastegate would only open at 25psi, welded an adjustable section into the wastegate rod and set it to open at 15psi. Before then the wastegate had never opened.

Rebuilt again 5000km later. This time the cast iron sleeves were bored out and chromard liners reinstalled. Generic pistons, rings, liners and gasket set was bought from a reputable (supposedly) engine parts supplier.
Half the gaskets didn't fit, found out later a genuine gasket set would have been cheaper.

For the next 27,000km I waited for the engine to bed in, stop burning oil and blowby to drop. It didn't.
I replaced both crankshaft seals with genuine items after the ones from the dodgy kit didn't keep oil in.
Coinciding with a turbo blowup (oil feed line came apart) the blowby got bad enough that the engine would run on it's own oil if loaded up enough.
The source of evil this time was again dodgy parts. The aftermarket piston, ring and liner set contained chrome rings. Chrome rings and chrome liners get on like sand and vaseline.

The engine was rebuilt insitu with a genuine gasket set, aftermarket liners (free), aftermarket pistons (can't buy genuine individually) and genuine rings. Valve guides and seals replaced.

Within 30 seconds of being started up it ran so clean that you could see up the exhaust pipe, the difference in friction between the old rings and genuine rings was huge. Old pistons had to be tapped out with a block of wood. New ones pushed in by hand.
Fuel economy improved from 8.5 to 10km/l, oil consumption disappeared and from startup the blowby was minimal.

The moral of the story is pretty clear. Genuine parts don't suck.

I've currently got the engine out cleaning all the crap off from years of it blowing oil out every seal. I have some silly turbo plans too.

Would that be the 10% that you could have earned if you invested the cash :p?

[LoveMyV8County]

When purchased 3-4 years ago my V8 County had 224,000 on the clock. However:

1. When I stripped the motor for rebuilding it was already on first oversize bearings and had replacement (Holden) pistons.
2. It has a replacement (Borg Warner) gearbox
3. It has been registered in WA, then Victoria, then back in WA again.
4. I've just done the clutch and the one I replaced was not the original one.

Makes me wonder if it has been round the clock??

[DirtyDawg]

400,000km's plus is a great accolade for any modern vehicle;)

[EchiDna]

I gets me 10% in other ways :)

Mate, you have been ripped, raped, and robbed!!!!
I'm suprised you even still have the vehicle.

You were also lied to about the Isuzu pistons, you can't actually buy them in a set, you can only buy them individualy. Same with the rings and liners, and usually they are sold as a set. The piston, rings and liner. And they are pressed in crome liners, so they have obviously charged you for a boring job when you didnt need it.
Man I would have been swinging with that sort of service!

Not really. Most of it was simply ****ty aftermarket parts and a bad aircleaner. I have now learnt my lesson regarding aftermarket and genuine.

If you have a part number for individual pistons then I'd like to know, the aftermarket pistons currently in there are niggling at me.
There's no way the isuzu truck parts guy was lying to me and no reason for him to. If he could have supplied the pistons I would have bought them. But he could only supply matched piston/ring/liner sets.



And they are pressed in crome liners, so they have obviously charged you for a boring job when you didnt need it.

The boring job was needed.
The previous owner had the block bored to fit thicker wall cast-iron liners. They had to be machined out to the original bore size to allow fitting of the new chrome liners.
I could have avoided the machinging by simply dropping in another set of cast-iron liners. But no way in hell.

Apart from the block machining I have done all the work myself, so it's only wasted time, not paying for someone else to screw me around.

Mate I hate to be the bearer of bad news but I think you might be in trouble with this engine.....

double lining does not work all that well and unless youve got stupidly tight liners or tophat the inners over the outers they are more than likely going to "squirm" in place which aint all that cool.

Find whoever installed the oversize cast iron sleves and kick them repetedly in the behind....

Id suggest that as a precation to installing your cromes inside the casts that you preheat the cast iron sleves to about 120ish degrees and the put the crome liners in the fridge. They'll still need pressing in but if you do it quickly with one of the screwjack type seaters you might get away with running the inner sleeve as an interference fit.

All Isuzu liners are "tophat" style, they can't slip down.
The engine has covered approx 40,000km since at up to 20psi boost, so the testing is well and truely over.

Many engine rebuilders use the cast liners for two reasons. The first is they're convinced the original bores aren't round, the second is cost.
Anyone mic'ed up their bores to see how round they are? I suspect they're mostly making up stories to justify reason #2.
