anybody else have any oil analysis data to share?
 
were these the cerakoted bearings? how many miles on these?
no those are going in my engine, this is a customer's 200,000 KM on them I'm almost sure they are original.
 
Almost certainly original IMO

Vast majority of 1hd-t in Aussie cruisers have never been opened up.
Guaranteed the average mileage wood be over 200k km

I wouldn't be so sure. I know several people who had HD-T's rebuilt at lower mileage. Oil consumption was the problem with one.
Australia was ground zero for the BEB problem because they can spend a lot of time driving in one direction at one speed. If that coincided with the speeds oil cavitation happened in the bearings then it was all over rapidly.

Here in NZ the driving is way more varied and we didn't have the same problem.

Low mileage rebuild are an exception, not the norm.
Do/did they happen? No doubt. Not disputing that at all.

One was a mate who bought it already rebuilt. I don't know the reason why and I don't think he did. Another bought one that seemed original and couldn't get on top of the oil consumption problem. He put a new long-block in it.

Both were before 2010. So vehicles approx 10-15 years old. The 1HD-FTE was a lot more reliable than the 1HD-T.
 
This was my report from about a year ago on my euro HDJ80 @ 336,000km. unsure if BEB's were ever done, but planning on doing them anyways in the next month or two

Posted this a while ago as a newcomer introduction and only just stumbled onto this thread, figured the info would be more valuable stored here.

Summary:
Defused a time-bomb with 1s left to go, I think I was about to send a rod to god.

1994 HDJ80R 1HD-T @190k Miles.
I believe these were the original bearings. Replaced with standard spec ACL.
Ill consider myself very lucky.

Did you say these were changed 2 years ago or you suspect they are originals?
Ive edited my post, that wasnt so clear was it...

I suspect these were the original bearings, previous owner who knew the long term previous owners had it as a belief that toyota recalled the 1hd-t for BEB's. Luckily i didnt believe him.

Very unusual wear pattern.
 
Hello all! Jumping in on this thread to educate myself and also to get notifications as it continues. I'm a new owner of a 1994 HDJ81 with 1HD-T. My rig came from Japan and runs excellent @ 212,000 km. I have no clue if the BEB have been replaced, so the subject is on my radar. Are the oil pressure gauges anywhere near accurate on these things? Is pressure any kind of indicator? Mine settles lower at idle with a hot engine, and raises to the mid point or slightly above at RPM. Additionally, I was informed by a source that is well versed in these things that the bearing issue was more a 91 / 92 thing? Looking forward to growing with this machine, and keeping it happy and healthy for years to come.

94 HDT owner as well. This job was intimidating but not bad. My BEB didn’t look too bad but I’m happy I did it. Plug the Taiho bearings part number into Partsouq they can be had for like $25. And some Aisin FIPG. That’s all you need! And an oil change :)

No the gauge isn't accurate
No it's not an indication of failiee

I've done some digging, and it doesn't look too tough to do. Unfortunately, I just moved (to the country) and I don't currently have a suitable place to begin the work myself. In my area, it looks like diesel mechanics are all afraid to do it for me. On the Taiho bearings, I have to assume my mileage is original and no motor rebuild in the history. Did you just buy STD size and slide them in?

Get some plastigage and measure first. Likely they are standard bearings but better to be sure?

The hardest part is getting the oil pan to part ways with the block. Esp if it's been sitting there for 30 years or so.
