Isuzu 4jx1 Injector Re-seal
Вставка
- Опубліковано 8 лют 2025
- In Today's video, we are going to be resealing a set of injectors, oil rail, and Injector sleeves. This engine had an oil leak in the rail and was losing oil prime overnight causing hard starting.
Also if you are getting diesel in your cooling system or coolant in your fuel tank this reseal also deals with this issue.

Wow amazing work You can bring links For a set of rubber bands and discs Complete as you did? And sorry if I'm not clear I'm with Google Translate
Sorry not sure what you mean when you say “rubber bands and discs” Thanks for checking out the video.
Great and thorough video, thank you! I suspect that I have diesel mixing with oil and pulled the injectors and sleeves out. However, when I removed the injectors, they had two o-rings and one metal ring that kind of fits on the shaft over the o-ring on the injector, but I don't see that metal ring in any videos or pictures I have come across. There is also only one o-ring groove on the injector, so I'm a bit confused. Perhaps the other (larger) o-ring was someone's own addition, because sometimes they stayed in the sleeves when I pulled out other injectors and sometimes came out with the injectors. But does anyone know what is that metal ring, is it supposed to sit there in the space between the injector and the sleeve? Is it a part of the sleeve? There is only one groove. Between the sleeve and the head there are two o-rings.
The injectors were fairly clean and shiny, no discoloration or carbon buildup (except the nozzle) but the sleeves showed some wear between the upper seal and the top edge, so probably fuel indeed had been flowing towards the camshafts mixing with oil. I'm not certain though should the sleeve be replaced entirely in this case or would it be good enough with new o-rings. There are no scratches but it is clearly not as shiny as the opposite side.
The electrical connectors/plugs were also broken by the previous mechanic and were held in place with wire and zip ties and the rubber seals were in a pretty bad shape. Does anyone have any tips with those?
Hey Heikki, you can purchase new ends for the wiring loom. I will have to research who I got them from and let you know. The injectors only have 1 x o-ring about half way up the injector body. I have never come across a metal ring with an extra o-ring before. I think you may be correct in thinking this is something someone has done on a previous repair to try and help with sealing. You need to purchase genuine Isuzu o-rings as the after market ones will fail. Good luck and thanks for checking out the channel. 👌💯
@@basketcasebuilds5712 Thank you! I tried to include a google drive link for photos here in the comments, but it keeps disappearing. Anyway, the ring is located just above the sleeve on the injector nozzle and there is just enough space for an o-ring, so I guess that's where the extra o-ring was. I was also told that the wear/dullness on one side of the sleeve may be caused because the injectors have not been torqued down in the correct sequence and the sleeve been pulled over to one side in the head towards the oil rail. Could be. I managed to place an order for new sleeves and seals from Dubai.
@@heikkihyvanen you can send me an email if you like basketcasebuilds@gmail.com if it makes it easier to send photos

Wow, that was so detailed with torque specs AND full parts list + supplier. If I could I'd do it myself too, but years have caught up. Any ideas as to how I would go about finding someone in VIC that can actually do this quality work for me? I haven't come across a mechanic that has actual experience working with the 4JX1 and the guys at the Jack Club VIC don't know anyone that still works either...age takes a toll in many ways!
Hey Benny, here is a link to the “Australia4wD Forum”
forum.australia4wd.com/index.php?/forum/60-4jx1-30-tdi/
these guys might be able to help you out. I live in NSW unfortunately and with this COVID-19 thing going around makes it hard to travel.
Good luck finding someone.
Thanks for the comments and taking the time to check out the channel 👌
@@basketcasebuilds5712 Thanks for the reply. I'll check Australian 4WD forum out. out
@@basketcasebuilds5712 I haven't had any replies yet, but I think I've sorted and sourced the Tech2 tool and software cartridge to let me diagnose it.

Mine got very hard to start over a month, now wont start at all. Cut white wire, still no luck. What should i look at next? Injector seals good so far.
glow plugs and air on the suction side of the fuel system. Thanks for watching.
Thank you for this video. A very good lesson for my own experience. I am from Russia and we call this car Bighorn. Many people say that this is a very bad engine and change it to the previous one for this 4JG2 car. Please tell me if you need to disassemble the injector? I heard that there is also a rubber ring inside and when it wears out, the fuel can get into the crankcase with oil. Is this so or is it better not to do it?
Hey Thanks for checking out the channel. I have never disassembled an injector. There possibly could be an o-ring in the injector but I never had a problem. Fuel can get into the oil when the top o-ring leaks between the injector sleeve and the cylinder head. Here in Australia there were 2 recalls one for the injector sleeve O-rings and later they changed the injectors out for modified ones in the second recall.👍

my engine produce a lot of smoke. is this can be a solution?4jx1
Maybe or could be a turbo
Could you tell me the catalog numbers:
Rail oil pressure switch - RP
Oil temperature sensor - OT
www.catcar.info/isuzu/?l=
Put your VIN number in and lookup -
0 - Engine, Emission, Engine Electrical
then
0-52 - OIL AND VACUUM PIPING; ENGINE
You then pick 4JX1 and the first picture will have the 2 x sensors.
Item 495 and 496.
Bookmark the page and you then have a complete parts book for your VIN number.
Cheers
Thanks for the info mate. I am about half way through that swamp myself. I am a bit thick but i cant seem to find the link for your supplier. I sourced some on the gold coast but $270 later and half the o rings are wrong.. just wondering if you could push me the link i know it is pretty academic now but did u notice that the o rings that you took off the injector sleeves are a different thickness to the ones u put back on. My kit came with the thinner ones and when i fitted them they sat down inside the groove and would not have sealed much at all. Once again, thanks for the video, much appreciated.

If someone doesnt have the tools to engineer a tool for removing the end caps on the oil rail, can it be purchased? if so where abouts? Cheers for the video I just bought a 2000 jackaroo and have to do the same procedure
Thanks for checking out the video, I couldn’t find a tool when I was looking. You can use stilsons on the cap and lock the rail in a vice. But seriously it was just a nut ground down with a grinder. If you don’t have the gear I would see if any engineering shops or mechanical shops might make one and remove and install the end caps. Good luck
@@basketcasebuilds5712 thanks mate
When oil and diesel mix what is the problem.
The engine can run out of control if it starts to breath heavy diesel fumes through intake system, if fuel is leaking into the sump.
Thanks man!
No worries, Hope it helps
Hello, nice video very informative. What is this grease at 19.05 please? Thank you

Hi where did you buy the special tools that you use for pull out the housing of injectors?
I purchased mine from a guy on a 4x4 forum forum.australia4wd.com/index.php?/forum/60-4jx1-30-tdi/ There is also a link to an Amazon one in the description. Thanks for checking out the channel. 👌💯

Great! Thanks.
You're welcome!
Is there a possible if the injector having problem, the diesel and oil can mix up?
Possible o-ring failure on injector or top injector sleeve o-ring is letting fuel past. These engines can runaway with diesel in the engine oil and cause damage from excessive engine revs please be careful.
Also have a look at this write up

How long can one expect this fix to work? Does it need to be done regularly?
Some people say every time you do a cam belt (100,000 kms)
Pode mandar as referências das peças por favor ?

Hey mate where did you get spring pins for the injector sleeve remover
I purchased this off a guy from the “ Australia4WD forum” he made it. You can purchase a more OEM style puller from Amazon Australia. I’ll try and find the link

@@basketcasebuilds5712 i am pleased to see the tool I designed and made.... is still going strong,
I like your idea of the grinding a nut down for the rail end caps
Thanks for your comments and checking out the channel. Your tool got me out of trouble and I still have it hanging on my wall.👍💯
Tengo que no le llega el aceite en el piko
Bien, verificaría que la válvula de control de presión del riel de aceite funcione y permita que el aceite llegue a la parte superior del riel. Está ubicado en el lado izquierdo del motor debajo del colector de admisión hacia la parte delantera del motor. He tenido problemas de arranque con esta válvula antes. Aquí hay un video que encontré que muestra la eliminación de uno. Gracias por ver el canal. ua-cam.com/video/ToYnUfWMUEo/v-deo.html
Price for fuel injector
Email Ramin Auto parts and they will send you a quote. Email is in the description. I have never purchased new injectors. Thanks for watching. 👍
How long did this take to do?
Took 2 half days in the shed once I had all the o-rings. Thanks for watching 👌
is the inejctors after rebuild need to be reprogram?
I didn’t and they worked fine. I put them back in the same location they came out of. I think injectors need to be calibrated if they are new or from another engine.
Why oil and fuel mixsing
Due to the O-ring blowing out in the coolant passage and fuel passage in the head that is located on the injector tube
Can you fix mine?
Sorry, mate no time to do much at the moment on vehicles with house extensions happening. Thanks for watching👌
