    Removing CT26 and inspection

    Hi, 1) what is the easiest way to remove factory CT26 on 1HD-T? Should I take the manifold off like the FSM states or just remove the turbo? 2) key steps to follow for inspection? I experienced a turbo fault at low speed and shut it down immediately. I had a pressure release sound under boost...

    1HD-T idle problem - need help!

    A belated thanks to all that assisted with suggestions. It has been a long, frustrating and expensive process. I hope anyone else unlucky enough to get this symptom can now resolve it. It is a good reminder to always start any trouble shooting with the least expensive option. It would also...

    1HD-T idle problem - need help!

    It did not actually have the miss during that period. It had some other idles issues, but that was following a number of pump rebuilds undertaken by an incompetent fuel shop. The new dashpot didn't change anything then. I did find during that period that the dashpot was disabled also. Yotahead...

    1HD-T idle problem - need help!

    Long story short: after being asked to test everything under the earth the outcome was that fueling was the only possible problem I.e. Pump. A short spray of ether actually resolved the miss. After a year of back and forth and parking it up for six months inbetween, there was talk of governor...

    1HD-T idle problem - need help!

    Update: Do not spend a cent or waste anymore time than you already have looking for the problem. This afternoon I fixed it. Get your trucking to operating temp. Make sure idle us within spec for your transmission type. Screw in dashpot very steadily, blipping throttle to settle the miss as...

    1HD-T idle problem - need help!

    Yes I've tried a fuel supply from can and it does not change. Governor spring is new.

    1HD-T idle problem - need help!

    It would be worth taking a fuel sample from your filter in a narrow glass and try shining an LED torch through or using a strong magnet to check for rust particles. I did this a few months back and saw nothing, but apparently it can be small enough to pass the filter. We still don't know...

    1HD-T idle problem - need help!

    You might be in luck due to my bad luck. I have the 80 in the workshop this week. It has had a leak down test, another compression test and valves checked. All OK. Spraying Esther into the inlet whilst it's idling rough resolves the problem in the same way applying throttle does so we can...

    Stock 1hdtft upgrade to Gturbo Badboy or Grunter ?

    Interesting. Did it not present the same issues on their dyno when they tuned it? I would have thought you could beat 14l/100 on an intercooled FT at highway cruise.

    Stock 1hdtft upgrade to Gturbo Badboy or Grunter ?

    Hi, I know this is an old post but interested how EGT and coolant temp issue was resolved - def not what you would expect from what GTurbo advertises. Sounds like way too much fuel?

    1HD-T idle problem - need help!

    Team, I started the 80 again on the weekend and drove it with AFR gauge hooked up. I had not done this since the injection was replaced. It is still showing 24-22 at full load and boost (11psi) but starts heading south to the 20:1s in the 2500 rpm range and into the 18s close to 3000rpm. I...

    1HD-T idle problem - need help!

    I sourced the genuine axle housing via Mike Carney Toyota in Townsville who tracked one down at a Sydney dealer. There were not many left. It was around $1600 from memory and I used the later ABS model part number as I think the early one was obsolete. The only change was a bracket for ABS...

    The link I sent has adjustable pressure switches either side of the preset. The air intake temp switch would be worth examining too, or as I mentioned the pyro if it has the relay trigger function.

    The official 1HDT Intercooler thread

    Sorry I have not tried it (no IC yet); just an idea. I've got a fair bit of stuff through that instrument shop though and they are good for advice in that context. I imagine there is bugger all heat at 4psi so IC isn't doing much and the fan could have a rest? That way it won't mess with your...

    The official 1HDT Intercooler thread

    The big front mount would be awesome but I'm in the same boat with lots of additional gear floating about. How do the factory VDJs manage this scenario with the top mount? I'm def no expert, but I just can't see a fan with such a small motor flowing high cfm having a 100% duty cycle. Good...

    1HD-T idle problem - need help!

    The only issue with this theory is that the problem was the same with the previous injectors and pump. It went away for a few thousand km then came back. Yes it's def a rhythmic miss. Yep the governor spring has def been replaced.

    Perhaps by pressure (boost): Adjustable pressure switches NO/NC Or temp if there is a probe with a switch suitable? My digital pyro which is an ENG-TEK can switch a relay via a pre set temp. May work but in your instance of long flat roads with high ambient temps possibly not.

    I think you need to introduce some type of thermal cut in/out whether it be by EGT, IC inlet temp, IC outlet temp or boost.

    You can get heat shield sock tubing which slips over cabling - can use it for spark plug leads close to extractors etc. might be useful. There is also heat shield adhesive tape. Not cheap but works well.
