Things are still good, got it back on the road after the new motor and I've put 30-40,000km on it since then.
Never confirmed what cause the failure but most people think either injector or blocked coolant passage as dougal suggested.
We returned home in 2018 and I've been daily driving it on...
No problems! Amazon shows they have them available for ~$900 and in stock

I believe this is correct yes, I have a bad injector to send back with the core so I am going tosend injector #2 to the place that built them for analysis...
Before failure it is hard to tell because my only experience with the motor was as it was. It did seem to have a rougher idle then it...
Inspection of the pistons was only visual, I did not have any special tests run so its very possible it started before
I inspected the motor today and took a bunch of pictures. Skirt of piston is scored and the ring lands were melted a bit
Sleeve was scored as well
Injection nozzle had...
Hey,
So I found a few trucks with a 4bg1 but I didn't find any with the 4bg1t, thinking hard about an oem motor at this point, especially if it comes ready out of the box.
If I were to find one I see the 4bg1 is higher compression, 17.5:1 compared to 17:1 but do you know if there is anything...
I haven't ordered any parts yet and I don't intend on doing so until I know what is wrong.
I have confirmed in the past that the spray pattern of the 4bg is different but I am using the 4bg injectors from the motor matched to the serial number of the block and therefore pistons, so that...
it seems to me that the 4bg1t piston recess is more ideal because it is round, I would think having a square recess would be less ideal, thoughts?
I'm going to stick with the 4bg1t pistons regardless, but I find the topic interesting.
I believe you are correct for the US and canada market and...
Yeah, I saw the limit of 1.5 and had to look at it a few times to make sure I was seeing it correct!
I did not know there were truck applications of the 4BG1T, I did know there were marine applications but they stopped making marine diesels a while ago for some reason. I'm pretty sure my...
So how did you determine what your ring gap should be? Did you use a formula?
This is from the Isuzu 4bg1t manual:
Piston Ring and Piston Ring Groove Clearance mm (in)
1st Compression 0.35–0.50 (0.014–0.020)
2nd Compression 0.60–0.75 (0.0236–0.0295)
3rd Compression 0.60–0.75 (0.0236–0.0295)...
Wow that is quite a bit of abuse! After all of our time in the desert, I noticed dust in my intake piping too.... I have been dilligent about replacing air cleaners very very frequently, however I had stopped at a place to get my valves adjusted while my wife and I explored the town, and I did...
Current pistons and liners were the OEM ones, they were in good enough shape to re-use, or so it seemed at least. Pistons were the bowl shape with the cone in the center if I recall correct
I used OEM rings which were supplied based on the serial number on the block
750C sustained, holy, how...
