HOW MANMY KLM IS TOO MANY FOR A 1HDFTE?

[cruzinto]

Hi all just looking for an idea on high klm in a 1hdfte 100 series, apart from injectors and pumps is there any major issues that seem to be common? The 100 I'm looking at has over 300000km on it but with all service history up to date, mainly highway km with some towing included just want to prepare to barter if there is anything I can see as a future issue thanks.

I'd focus on driving it and seeing what is currently wrong with it. Parts worn you can actually point out to the seller is more likely to affect the sellers decision than your 'word' that this part will go out in x amount of kilometers.

300k is high for any vehicle and you should be checking every aspect of it if you want to avoid suprise near future repairs.

The motor alone is probably in good condition if mainly highway kilometers, and serviced every 5k kilometers.

the 1hdtfe isn't the hardiest motor and I wouldn't expect to see 500k without problems under normal circumstances. Higway k's and treated well then it's a more possible achievement. Don't buy one thinking it will do a million kay's because the truth is majority of motors don't even get half way there.

We have a customer who has over 400k km on his and tows a 3.2 tonne trailer on the back every day for work.

Apart from the usual timing belt, injector lines, and ball joints in lower arms, we have done a secont Bilstein Platinum suspension package in this car after the first one finally wore out at 360 k km, and a pump overhaul, the rest goes ok.

I would expect, given we see 750k km + 4.5 petrols, and 12v 1HDT's with the regular maintenance, I wouldnt expect the 1hdfte to be any different.

I saw a Pilots 100 with just under the mil, he had just had it tested and was still within compression specs.
well maintained car that ran for like 8 hours a day every day

one thing is for sure they will out last a 1HZ
with its crappy "precrack" chambers

Thanks for your input guys, took it for a run today and allthough it ran and sounded all ok it drove and went like a cruiser thats done 300000km too! I think I will be looking at spending more and getting a lower km one even my old 80 with the same km's drove and went a lot better, can't see the point of spending good $'s without a major power and fuel gains which it didn't have.

Care to elaborate further? Can't see why that would be an issue for a properly maintained one.

So if you are comparing a TD 80 series to the td 100 series then there really must have been something wrong with it for it to not have as much power let aqlone more as your similar km 80 because they put out significantly more power power from new than any 80 diesel ever did. Probably a good decision to walk away unless it could be explained easily and believeably and fixed cheaply.

Given this engine is a development and update on the original 1HD-T and 1HD-FT I can't see any aspect of it that would make it any lesser of an engine that the originals were nor any reason for it not to reach those sort of km's. What is the apparent issue.

Plently of modern engines are easily capable of pulling 500,000k's if looked after sensibily and normally, heck even our under powered and weak and very underrated RB30 powered GQ was still going strong at over 350,000 k's (last time I caught up with it) without anything more than a new radiator which only got replaced as the original eventually rattled itself to pieces.

Comparing it to my 4.5 80 (the power house it is!!!!), I wanted to upgrade to turbo 100 but after driving it I was very dissapointed in it's off the mark lack of power and lack-luster highway cruising didn't even seem to have a great deal of torque either. Must have been the high km's as my 1hdfte ute with 80000km on it would smash it, and on the way home I drove a low km one and it was awesome compared to the one I looked at buying? It had a new injector pump and a cp chip too so not too sure what it's problem was just very dissapointing to drive and when I stopped a few times and the aircon cut out and the revs died down it seemed to have a very noticable miss in it? Will be staying well clear of it anyway.

what it comes down to his how it's driven. round town and short trips with not much load. Also as far as a diesel go it's a high reving engine, producing max torque fairly high up in the rev range. It needs to rev but some lazy manual drivers don't bother going back gears.

Running oversize tyres is also an issue as it lowers the gearing and loads the motor up.

the only motors that go 500k+ are ones with alot of highway kays and properly maintained

Properly maintained is an issue too as there are people out there including 'mechanics' who think 10k services are ok. The injectors are often overlooked aswell.

I would not call them hi reving unless you r comparing them with a cummins or something like that
i have the opposite opinion with mine i find max torque is available from just over 1200 rpm so no need to rev it at all to make it go

also the final drive is taller than for a 1hz diesel so that means it revs less to do the same distance

with regard to the servicing i had a 1hz turbo and now have the 1hdfte the oil out of the 1hdfte after 10000 is far cleaner than from the 1hz after 5000 this is because of the EFI

the oil is kept far less sooty and contaminated and runs cooler (compared to its indirectly mechanical injected cousin)
so it does have a longer life span as it is not coked up i think you will find toyota its self has extended the service interval on this engine

So what you are really saying is it's not a function of any design or manufacturing flaws wiht the engine itself but rather how good or bad it's treated. Like any modern engine really. I would also agree with thrashlux, I have one in my 80 series with 35's and it is far from a high revving engine with good torque fairly low in the rev range. Don't know exactly where as my tacho is not yet working but although it is no Chev diesel it is far from a 4 cyl common rail buzz box.

Anyone selling a wreck with the 1HDTFE in it? I know i saw awhile ago someone was sourcing utes for people in need, anyone remember?

[4runner2.8]

the gutless one you drove would have been a 4 speed auto yeh? the 5 speed was a massive improvment over the old 4 speed in off the mark performance.

[cruzinto]

No 5 speed manual the good one was a 5 speed auto, heaps of back lash in the manual too have driven a few 4.5 and 1hz gxl 100's but this one has the most in it.

[oldmate]

I'm not disputing the 1hdtfe has plenty of torque from about 1400rpm, but rather that longetivity is affected when you constantly load up a diesel under it's peak torque rpm. That's about 24 or 2600 rpm in those motors.

This isn't just a toyota diesel either it affects any diesel

The point is a false sense of performance and/or reliabilty from this low down torque. Just because it pulls away from nothing in a high gear doesn't mean you should.

The original post was about a diesel with 300k on it so I just stated that they don't 'go forever' and that the 1hdt isn't hardy in a way that means you can totally abuse it and still get a million kilometers out of it.

[bj on roids]

Our work 80 with a 1HZ is at 450k and counting, and it has had a HARD life.

It doesnt like parking on hills either, compression seems low, yet it seems to drive quite well??
