1KD Piston Technical Service Bulletin

6 COMMENTS

  1. Any chance of adding a link to the Toyota Service Bulletin about the different injectors and pistons ? It is very hard to read from the YouTube video. I have a 2006 type 1 Fortuner with 1Kd ( bought new in Thailand but brought to Australia in 2011. I believe originally was Euro2 so hopefully no piston issues. I DO tow a 1800 kg caravan in Oz….Now has 190 k km so I guess time for injector change.

  2. Hi, Thanks for the advice.
    Presently I have an issue with my 2013 Prado. This morning it lost power. Oil & water & temperature was fine. It looks like my No. 2 cylinder stopped working. Power is down to 15-20%
    Unfortunately, timing is poor. I’m towing a small caravan from one side of Australia to the other. I’m stuck at an isolated fuel stop. The nearest town behind me is 470km and the nearest town in front of me is about 750km. I can drive at maybe 60kph and right now I have a little bit of internet. I wonder how much damage I will cause by trying to drive on 3 cylinders.

    • Hi
      I would not recommend you to drive the car any further mainly if you don’t know the exact cause of the issue, because there is a high chance that you are gonna end up stranded with a seized and ruined engine-mainly if you plan driving that long distance.

      For example, if you have a cracked piston(-with a crack on the side of the piston) and you are gonna drive the car, then because of the heat and the crack the piston expands more than it should and it can get seized a lot which is gonna damage not only the engine block but also the crank.
      Also if you have a leaking injector, then that is also gonna cause a cracked piston-if its not cracked already + the excess fuel will get into the oil – and too much fuel in oil will cause a seized and ruined engine.

      The only time I would maybe drive the car would be if the injector is stuck in closed position and the piston would be fine with no crack-or if the crack/hole in it would be small and not on the side. But the problem is that you can’t check this properly without looking into the cylinder, and even in that case I would not drive the car more than 100 km.

      Also, if currently your issue is just a small crack in the piston or just a faulty injector then the repair is not gonna be very expensive if the other components are fine, however with driving the car you can cause bigger engine damage which is not gonna be that cheap to repair.

    • not completely since these engines still don’t have the newest pistons fitted and there are rare cases of piston crack even in these versions, but there is a much much smaller chance of this issue than on the older engines

      the latest updated piston version for these engines was introduced in 2017 – this version should be the most durable
