The Toyota Landcruiser Owners Club

KDJ95 Prado. Hoped techstream would tell me what I needed to know, but I think on this older model you don't get as much data as on slightly newer ones. Any thoughts, or other symptoms I should be looking for?

Its done 212,000 miles.
I have service stamps and many receipts from previous owner, but none for injectors, so don't know if they have been changed before. Cannot still be in spec at 212K if they are originals.
Definitely less noisy once it warms up.
No smoke on start.
Techstream data inconclusive. When idling at zero load, injection volume is around 10mm3, have seen it jump up to 13mm3.
Drives good, no issues with power loss or using too much fuel.

Leaning towards just replacing them for peace of mind since they are rattly when cold. Maybe its just the washers needing replaced.

Well to check if the washes are leaking on 120 , 150 , hilux 95s probably the same you can look up through the oil drain hole with the drainplug removed whilst doing an oil change , at 212k miles if the injectors have not being changed will likely need changing as will the injector washes and Orings , I dont know if your ECU has the facility to give out injector values on the tecstream model that you have as that could be why you are not getting a reading . You could always try contacting the former owner if you can trace them and ask if the injectors have ever been replaced . Some one came to see me with a 2001 95 D4D with around 145k miles after a friend of mine asked me if I would take a look at his car for him as the Toyota dealers told him the injector values were over the limit, the car had a bad vibrating engine at tickover hot or cold and lacking in power , I could not connect my tecstream to it because the scart type socket which was in the engine bay was of the large type why bigger than the scanner plug I had , but what I did notice was his map filter was cracked at the bottom half in 3 places and the maf sensor was dirty and the Oring on it was snapped and had silicone on it on out side to seal it , I cleaned his maf sensor and sealed it for him but no change in rough idle  , I told him to get a new oring for the maf sensor 2mm x 28mm and new Map filter and to let me know if it cured the rough idle and low power but I never herd from him so dont know if cured his problem , he did say that he had toyota dealers fit the red and green SCVs at around 500 euros and saving up to have them fit new injectors at around a staggering 5 euro grand all in including pipes and fitting . But like I said I never heard from him again , I did see him drive past me on the road not long ago so he still has the car .

Interestingly, I did find another post of techstream readings from a Colorado 95.

This is the same as mine, giving injector readings titled "Revised Injection Volume #1/#2/#3/#4" but with values that look like a set of injector feedback values. So I think "Revised Injection Volume" must be the same thing as "Injector Feedback", its just got a different name on the 95.

On mine these are all sitting at 0.003. So perhaps my injectors are in fact very new and functioning perfectly?

In which case maybe the cold running rattle is something else.

Image link didn't work so will try again. Here is someone elses techstream screenshot from a 95 Colorado. Same as mine has "Revised Injection Volume" instead of "Injector Feedback" but I guess those must be the same thing just different name on the 95.

Your readings look much better than that one , your injection volume is lower as well which is good , full operating temp on  120s ,150s and Hilux 1KD-FTV are 83 to 85 c  that is when you base the accurate reading , dont know what the full operating temp on your 95 1KD  is ,

75 is as hot as I could get it today. I have put on an extra cooler for the auto box, and its getting a bit colder here, so maybe that is why my cooling is being so effective.

I feel like my injector 0.003 readings cannot be right though. Just watched another fourby4diesel video on youtube showing a truck with brand new injectors and they were all around +/- 0.1 to 0.4. Maybe the 0.003 is just a default it gives when it reads nothing.

Any idea what the Injection Volume should be? fourby4diesel has that sitting around 7.0 for a new set.
