For getting the motor to TDC, I used a "mirror on a stick" tool that I've had for years. That and a flashlight on the pulley and I could see the marks pretty easily. When you're at the "right" TDC, only the valves indicated in the FSM will be loose. 360 degrees on the pulley will get the...
You might have better luck in the "diesel" section of 'Mud if the moderators will move this, but I'll take a stab at it.
There are a few ways to do this. You can just re-arrange the vacuum hoses on the valves as in the photo below. Doing so will keep the EGR valves from opening when the VSV...
HaHa...No worries. Worst case, I get an overzealous diesel emissions tester someday who notices that my DR-2365 says I have a cat. I suppose then I'll need to go back to the technical center and get it corrected.
Yup.
Short answer is that they can't know. The task they've been given is...
My inspection was about a year and a half ago. See post #5 of this thread for details. Short version: I had the inspection, and they told me I had a catalytic converter even though I don't. My inspection form (DR-2365) says I have a cat, which hasn't been a problem yet, but I can only...
They almost failed me because the main fuel adjustment screw on my HDJ80 didn't have yellow marking paint on it (apparently the paint is supposed to show that the screw hasn't been tampered with). He decided to get a yellow paint pen and mark it himself. There, I passed.
I know of at least...
I read your draft--seems like all the necessary info is there.
Really it boils down to convincing them of two things:
1. Your Landcruiser didn't come equipped when new with a catalytic converter because no 80-series diesel had one.
2. Because the original exhaust system didn't have a...
Some did, some didn't. Depends on market (or more correctly, depends on the climate in any given market). My last 1HZ was from Europe and had one. In Australia I'd be surprised if anyone there has ever seen one. Delete it, cover the hole with a plate, loop the hoses. You'll never miss it...
I think you're on the right track. Those guys always seemed nice enough when I've dealt with them, and they don't seem unreasonable. If you can bring the receipts, so to speak, they should see the light. You may need to give them a delicate lesson in the differences between a resonator and a...
Thought so. Do you have any Toyota documentation that would verify that info for @urhc2 to use when he returns to the technical center? I’ve dealt with those guys several times. I think if they saw it in Mr. T’s own hand, they’d believe it.
I don't speak for the State of Colorado, but that's what I'd think, too. Makes sense.
Toyota diesels started using cats in some markets in 1998. A cat for diesel has different construction than one for petrol, but serves the same function. Modern diesels all have them AFAIK.
Yes and no. It's correct that the Federal 25 year rule is for safety standards (NHTSA/DOT), and that the EPA exemption is less (21 years), but the EPA exemption only applies if the car's motor and emissions equipment are in "original unmodified condition". In other words, if your car's...
Sadly the Colorado Front Range is not Idaho--it's getting more and more like California here. To get a foreign-market car to be emission compliant here is a two step process: First, have the vehicle inspected at the Emissions Technical Center on 2nd Ave in Denver; and second, get a tailpipe...

That's about US$60 plus shipping. Good quality kit.
There are others.
I wouldn't argue any of this. Agreed on all points. I was only answering the OP's question re: a comparison of the two motors "in normal use", which I (perhaps mistakenly) interpreted to mean unmodified. In that instance, value for money goes to the 1HD-T in my opinion.
The OP seems to...
No. The jump to 24-valve was a look forward by Toyota to the future of emissions requirements and thus the need for higher combustion efficiency. If 24-valves gives higher performance, it's minor and that was probably just a bonus to them.
The earlier 12-valve motors are a bit simpler and...
Just posted the RM437E (engine) and the ERM111E (emissions system) Manuals in the "Resources" section of 'Mud. The files aren't perfect, but it's all legible.
