  • Rings busted, need short motor, engine overheated? WTF?

    Hi Everyone,

    I thought I would start a new thread to document my engine woes. I hope it helps somebody along the way. Please feel free to comment..

    I drive a 2006, 120 model Prado with the 1KZ Turbo Diesel engine.

    I purchased the vehicle new from my local dealer and have had it serviced by the book. Around 80, 000km I noticed the car was under-powered and sluggish. I found myself downshifting several gears to get up a decent hill on the highway. It just had no guts.

    I mentioned this to my licensed mechanic at the 80, 000km (under 3 years) mark and he agreed she was underpowered and questioned a faulty turbo. So it went back to Toyota and the Turbo was replaced at 80, 000km.

    Just prior to the next service at 90, 000km the engine oil light came on. At service my mechanic found the engine oil was low and found oil in the intercooler. He questioned blown piston rings.

    THIS IS WHERE I KICK MYSELF. I can only blame myself but for some stupid reason I have not gone running back to Toyota when my mechanic found oil in the intercooler, questioning my rings (90,000km, under 3 years). I guess I didn;t realise the significance of what was found, and I feel a bit let down by my mechanic for not really explaining the significance of this.

    Anyway, I have continued on and had service after service with no real issues, the oil light had not come on again and she was going ok.I still found the Prado generally under-powered, but I have never been a speed freak so I have motored on with it.

    At the 130, 000km mark she was almost due for a service and my engine oil light flickered on again. I had to put in 3 Litres of oil to bring her up to high. At service my mechanic again found oil in ther intercooler and said get that thing to toyota.


    Toyota spent a day on it initially and said I have no compression in the 4th cylinder. I had to put 2 weeks aside for it to be stripped down and properly diagnosed.

    It has now been stripped and they have found that I need a new bottom half, or short motor. The piston rings have lost their tension in the 4th and 3rd cylinder, and there is evidence THAT THE THING HAS OVERHEATED ?? AND BEEN UNDER STRESS?

    My mechanic has also examined what Toyota have fouund and agrees with their prognosis. The scary thing for me is I have never thrashed the thing or had it overheat on me. I have never had any trouble with coolant or overheating?

    So, if I get a new bottom half of a motor, will i still have an engine overheating issue??? How many Prados are overheating without any indication on the gauge?? :shock:

    That;s what I am up to now. I am trying to get an Out of Warranty consideration, but I am not holding my breath as there is evidence the thing has overheated.

    I will probably get an answer from Tyota on Monday..but I think I have to go see the bank manager.

    If I had my time again I would have been more assertive with my licensed mechanic and toyota and tackled this issue when it was still in the warranty period ops: ops:

    Could be a very expernsive lesson :shock:

    Doesn't sound good, you mentioned in another thread here viewtopic.php?f=2&t=10101&p=136401#p136401 that you were only changing the oil every 10,000kms for a period. I imagine that would be enough for Toyota to walk away from the problem regardless of whether it was the cause of your problems or not.

    Best of luck though. While it looks like being an expensive lesson for you, hopefully your writng about your problems might help save someone else from the same or similar problems/expense.

      Thats bad news.

      Am I reading this correctly. You had Toyota replace the turbo at 80k and then the oil light came on just before 90K. Oil plays a large part in cooling an engine particularly keeping the internals cool and obviously lubricated. If the oil light comes on it indicates low pressure. Very very low pressure and this would be enough to damage no4. This would have been enough to kill the rings, score the bore and drop the compression. So while they are saying it 'overheated' that is probably not in the sense of overheating due to a coolant issue. This is evidenced by the fact that the head is fine which is the first culprit when its a coolant issue.

      Your temp gauge may never had registered the fault so you would never have known.

      The problem IMO lies with the response to the excessive oil use following the warranty repair on the turbo. By not going back to Toyota you may have weakened your case.

      I hope it turns out for the best.

      cheers

        Quick little update thus far...

        I picked up my Prado yesterday after 5 weeks in the Toyota Worshop. In a word, it purrs :P :P :P

        It has a new short motor in her ($9,200 bucks in the end). I took her for a spin from Orange to Canowindra and return last night just to see how she feels and start to break the new motor in...it hasnt felt so good for such a long time. I can actually easily break the speed limit now :twisted: :shock:

        I am now going through the Consumer Trader and Tenancy Tribunal of NSW with a warranty dispute with Toyota Australia, as I can demonstrate my problems started around the 80, 000km mark. This will take weeks, if not months to reach conciliation, or a hearing in the CTTT, but, in the mean time I HAVE A NEW GREAT BIG POWERFUL ENGINE UNDER THE BONNET AND I AM HAPPY ABOUT THAT :P

        Tassie Tiger, you are on the money. My mechanic and I are arguing that the serious loss of oil that was experienced after Toyota replaced the turbo has caused this "overheating", or engine stress. I am quietly hopeful of my CTTT application but the result is some time off.

        As a side note. I am breaking the new short motor in. Using different gears at different rpms and speeds, not thrashing it, but not babying it either. As to frequency of oil changes, I was advised to change the oil after the first 5000km, then resort to 10, 000km oil changes and services again. This has been a rather expensive excercise for me. I will be doing 5000km oil changes regardless, as I now know first hand the damage that can be done if your engine is ever low on oil :roll: :roll:

        Thanks to those that have offered me some advice too. It is always appreciated. I am also collecting my old motor from the Toyota Dealership, and I am seeking further independent opinions as to what caused the damage, and whether the bore marks in my motor are original or not. Believe it or not, several people have commented that the engine does not look original so I am very confused by this :!: :?:

        Anyway, i,m going for a drive :P

          Good news Simmo.

          I think with your logical and non aggressive style you will do well in court. Best of luck!

            Simmo, good luck with your day in court. By the sounds, you should be OK, you raised the issue while in the warranty period.
            There is also a side of warranty that is an expectation of the item in question. Example, your engine should be good for 400,000km's but if it stopped working after 150,000 (even with full service as you've done) there is an expectation that this is still an unreasonable failure and while outside written warranty, there is an expectation that the engine should last longer. This will stand you on good stead in court.

            As for service, I always get mine serviced at the original dealer, for two reasons, one is warranty (extended to 6 years) and the other is for the above issues, they cannot lay blame on 'the other mechanic'.... Bear in mind, I travel 150km's round trip for a service...

              Good to hear Greg. So this isn't a 1KZ sitting in there? Got any detail on what they replaced it with including specs (power and torque). I've got a 1KZ but no signs of the issues you have experienced.

                Hi Scaffer,

                It's the 1KZ but when u have been running on 2 and 1/2 cylinders for ages it feels like a frigging rocket !!

                    Here's a couple of pics of the mill marks in the cylinders of my diesel engine (1KZ)

                    It has been suggested that these bore makrs are not Toyota original? Anyone here got any ideas on the subject. I am probably barking up the wrong tree here but I just want to make sure I am covering all the angles..a cylinder head specialist and my mechanic thought the marks looked "strange"

                    I have no knowledge whatsover in this subject, so please enlighten me anyone :roll:

                      That looks like scoring from the broken piston ring.

                        The up and down scratches are from broken bits.

                        The crosshatch marks do look a little hand done and not the uniform little diamond patterns that you sometimes see from computer controlled crosshatching from the factory. Could also be a trick of the light/curved surface etc.

                        I get what they are saying though. May need to see another block side by side to be sure.

                          This looks really good (maybe too good) nick to me. I am not a mechanic, but I have done my share of mucking around with engines. (all petrol, but)

                          Is this the state of the bores after the engine was taken down and cleaned? Nothing else done to it? That looks like relatively fresh bore honing markings to me. AFAIK honing is done to retain oil on the cylinder wall and to aid the bedding in of the rings in a newly assembled engine.

                          Read this:

                          To the naked eye, a freshly honed cylinder bore looks pretty rough in comparison to a used cylinder bore. Honing leaves a scratched surface that should show a strong crosshatch pattern. A used cylinder, on the other hand, will have a smooth polished appearance with much less crosshatch visible depending on how much the cylinder is worn.
                          So, this is the sort of thing I'd expect to see with a bit of wear on the engine: (random google images pic)

                            I believe that the 1kz have a simliar issue to the 1hz in that the pre-combustion chambers (both being indirect injected) swell and contract at a different rate to the head (being different materials) leading to cracks in the head and pre-combustion chambers which then leads to fluid loss and overheating and eventually leads onto engine failure. The events you describe sounds like a couple of people I know with 1hz (turboed), however firstly with high engine temperatures, then loss of fluid, followed by loss of power and engine blow by.

                              Well, some of you may know of my woes, altho Toyota did come to the party somewhat with mine, but lease was up, so, i bought a 150....glutton for punishment? Time will tell..but lesson learned is that tradein time is before 3 years and 100K! I have to admit.... the Bitsaremissing Pajero 5 year warranty was mighty tempting... so we will see if my ownership of the 150 restores my faith. Design wise, its not off to a good start (that i have documented elsewhere), and mechanically it does have the often mentioned flat spot around roundabouts and corners..so will see what happens at first major service at 10K.. so still tentative... but hopeful!!!!
