1Pz 70 quandry

[john_d]

I am considering buying a Toyota landcruiser 1pz 70 (1990). Two such vehicles are up for sale. One is white and the other one is yellow. Let me describe both the vehicles below.

White colored 1Pz70
Pros: Engine, transmission and differentials are factory sealed and are in great shape.
The engine has only travelled 150,000 Kms.
Cons: 7 yrs back the vehicle was involved in an accident. It was hit on the passenger side. The front left mudguard and bonnet was damaged. The front left pillar, between the driver and front passenger door may have also been involved. The vehicle was repaired and the damage does not seem extensive. The chassis seems to have been undamaged.

Yellow colored 1Pz70
Pros: The body and chassis are in great shape. It also has a winch and a factory fitted carrier.
Cons: Due to mishandling and neglect both engine and transmission had to be rebuilt at 120,000Kms. Subsequently, it has travelled 50,000 kms.

Which vehicle should I opt for? Some mechanics advise me to buy the white vehicle as the mechanicals in it are in great shape. They also say that rebuilt engines and transmissions as in the yellow vehicle are not as good as those that are original. However, others advise me to go for the yellow vehicle because it was not involved in an accident.

Please advise

Without the benefit of an inspection or pics ,who can tell? Are they the same price?

By what insight did they judge the rebuilt engine/gearbox to be inferior?
There is no reason why they cannot be rebuilt to a high standard.
I wouldnt want a vehicle that has had a damaged pillar,but maybe it wasnt damaged.

Too many variables.

Yellow PZJ70: Rebuild in 120,000 ks?!?!?!?!?

It will take some serious stupidity to call for a rebuild of that engine tranny combo at 120,000k. Somebody ran that girl ragged. IMO stay away from it with the info you provided.

White PZJ70: Accident "may" have been involved!?!?!? AND way too many "seems".

If you want to know what I would buy with the info you provided? I would go for the white PZJ70. Why? Because somebody did not trash a solid and durable cruiser to the extent of a rebuild at 120,000k as they did with the yellow PZJ.

Sounds like somebody is trying to negate liability with all the "seems" and "mays". I would inspect the white PZJ70 and see if that is a desirable cruiser to purchase. I would have nothing to do with the Yellow one. Somebody abused that girl real good for her to give up at 120,000k

Just my opinion with the info you provided.

Both vehicles were imported by the United Nations to my country, Nepal. The U.N. used them for 7 yrs (1990-1997) and then autioned them.

The white one was auctioned at 85,000 kms and the yellow one, the same year, at 128,000kms. Both vehicles were bought by local U.N. staffers who now want to sell them.

According to the owner, the yellow vehicle had to have it's engine and gearbox rebuilt because it was water logged in a stream crossing.

Mechanics, here in my country, tell me that it's very difficult to rebuild a transmission to that of the original condition. Is that so?

Secondly, if a chassis has been involved in an accident can it be ascertained from a simple visual inspection or can it be so subtle as to require measurement?

Thank you.

I dont see why it cant be rebuilt to a high standard. If the gears and splines are not worn ,it will only need bearings and gaskets.
If a gearbox is kept in use with bearings screaming and worn synchroes,that will affect the standard of the rebuild.
If it rebuilt before it becomes intolerable to the ears,then it will be ok.

In the end ,rebuilds are as good as the parts you put it in them.

The gearboxes from the factory sometimes die early and get fixed under warramty. My HJ61 had this happen to the PO,I know from reading the records.
It developed noises,got worse,toyota rebuilt it free of charge.

A 75 series work vehicle I sometimes drove emptied the t/case of oil on the freeway towing an excavator at 80 klms.
The t/case disintergrated and caused damage to the gearbox.
Toyota cried but fixed it free of charge.

Secondly, if a chassis has been involved in an accident can it be ascertained from a simple visual inspection or can it be so subtle as to require measurement?

It depends on the standard of repair. Even an undamaged chassis will not be necessarily be perfectly symetrical .
Your best bet is visually sight down the chassis and look for imperfections. A small ,well repaired bend wont hurt too much. But they can never be as strong again.

Bad repair jobs sometimes make the vehicle crab walk. On a straight road the rear wheels may be slightly off to one side of where the front wheels are traveling.

Whether or not to buy landcruisers like these depends on the price.

Thanks for all the info roscoFJ73.

I've since ascertained that the chassis of the white cruiser is undamaged. Due to circumstances I've also had to buy the white cruiser.

Where, I can download the owners manual for my 1Pz?

What engine oil should I use? We get Castrol, Duckams and Total brands of lubricants, here in Nepal. It's winter and the temps are between (0c-20c). What should the service intervals be like?

What about the Gear Oil?

Also, I've been told and also noticed that a rebuilt 1Pz or 1Hz seems to sound louder and harsher than an unopened engine? What does this mean for engine longevity and performance? Or is this a pump issue?

Can I replace the 1Pz with a 1Hz without any significant modification to the engine bay? Do I have to then change my 4 speed gearbox? If so, without too much of a fuss? I ask this because there's a 1Hz engine in greate shape, that I can get hold of.

Thanks

What about the Gear Oil?

Castro GTX diesel is used commonly in oz about 40-50. Castrol gear oil is also good,about 80.
Serice intervals are in the manual .

I have a rebuilt 1HZ and another that has done 200000 klms from new. The rebuilt one is louder but not unpleasantly so
. I have assumed its because it has a different type of piston or the cyl walls are thinner from machining.
There is no reason why it cannot last as long as a factory built engine,provided it has quality parts installed and the machining was of a high standard.
My rebuild has plenty of power and is fun to drive

Some of the 1PZ have a different 5 sp gearbox to the 1HZ and the 1PZ has a 2 piece flywheel. The 1HZ deserves a 5 sp otherwise it will not be much better than the PZ.

The type of gearbox is on the aluminium plate on the firewall along with the other details.
Im guessing yours will be a G40 gearbox as its the only 4 sp I know of fitted to a 1PZ.

i'm unable to find the link to the owner's manual.

How much engine and gear oil does the PZJ70 require?

Thanks
