    Anyone order the rotating assembly for the 1uz from Lextreme?

    I don't think any of the Lextreme products are being produced anymore as David (the original Lextreme) is no longer involved in the Forum or 1/2/3UZs.

    Rear end keeps puking

    The first 5 items are custom or purchased off the Internet. The driveshaft is a local item. The transmission comes out of what you can find.

    Idle air control motor

    Have you tried dismantling and overhauling your one? I'm sure there's a tutorial on that somewhere. I think it may be the Australian Soarer Forum. Perhaps Mr google can help?

    Newby , engine info please

    You may find it better value to buy a proven product and pay the freight and Taxes rather than try and re-invent the wheel and spend more for (perhaps) less.

    Blocked Fuel Return Line?

    As far as I know there are no check valves in the fuel return line. I've done 3 engine swaps with 1UZs and all have had open return lines to the tank. I would suggest disconnecting the fuel return line at the tank and ty purging it with air. if that is clear I'd connect it to the FPR and run...

    Newby , engine info please

    I can't answer the EGR question but W58's have been fitted quite often. The transmission is a little weak for the application so use restraint on the right foot. I believe Castlemaine Rod Shop in Victoria Australia is still making adaptors. Castlemaine Rod Shop No doubt there are...

    1uz-fe oil pan?

    There should be plenty of 131 sumps in Australia, New Zealand and Japan. I would think they would be very rare in the States. I'd start Googling for one.

    Classic ol' not staying running issue.

    With any issue after you have worked on the engine, try and keep your testing and replacement of parts to what you worked on. It stands to reason that as it worked before you worked on it the problem will be in the area you worked. Keep in mind the car is nearly 25 years old and a lot of the...

    Gee, I'm old and it was a long time ago. 2.2 Whipple from memory.

    Classic ol' not staying running issue.

    First up, don't go replacing the injectors unless you know they are faulty. This just opens the way for more issues. You need to methodically approach the problem. Even having all the vacuum lines mucked up or unplugged the engine would probably start. These things will run well on 4...

    1uz-fe v8

    The cam followers are best put back in the same location/hole as there may be matching wear patterns on the cam and follower. Don't worry if they don't go back in the same location/hole. What you will need to do is collect the shims and set the valve gaps on each valve. You will most likely...

    1UZ cad drawings

    I've never had a CAD drawing of the bolt pattern but I've built two adaptor. One for a Range Rover LT77 gearbox and one for a Nissan Patrol 5 speed. Both have been successful, one with over 1,000hp. Give it a go, nothing to loose.

    Heavy misfire

    Normally a misfire and 4 cylinders affected is electrical. I'd be checking each cylinder to work out which ones are bad. That will point to one or the other distributors. From there you have the appropriate distributors coil and igniter to check. I once had two cylinders down and they were...

    No spark on only 2 dizzy cap points?

    I'd swap trhe igniter plugs over and see if the fault swapped distributor caps. That will tell you if they are working. If they are the problem is between them and the coils or after the coils. If the problem swaps distributors you could have a dead igniter of a wiring issue back to the ECU.
