Here is a thought on the 1KZ - If you can find one - Go to a Latin grocer and ask if they know any mechanics. For my L049 I had a Salvadoran fellow do the work as he worked on many 4D56s before immigrating here. The same would be true for 1KZ

Good to know on both the amazon kit and the upper arms. How did they ship the arms to you? Duty extra? They look like the ticket for sure. Guess I better start saving...
Still leaves you with the knock. Hmm. Wonder if techstream could tell you anything about what the engine is doing? I haven't tried hooking it up to my 1KZ yet. Yours is even more advanced - maybe it could provide some feedback in terms of running parameters? I'm not sure.
Cool I'l check that out and report back. And hopefully get the sound nice and clean on video. It could very well be the case that I am just paranoid and the knock I hear is not a big deal.Any chance you can take a video of the truck running and share it? Alternatively, have a look online at see if yours sounds similar. 1KD's are known to sound a lot more knocky and ticky compared to the prior gen 1KZ engine due to the direct injection. The only other things I can think of is if timing is off. Unplug the crank position sensor and see if it runs any different? It should be noticeably different at idle?
The suction control valves at the back of the pump are also a likely failure point, but I'm not sure I recall them causing a knock to be the symptom.
That sounds pretty normal to be honest. Direct injection sounds like that. My BMW N54 motor sounds like a diesel some times with the noise of the high pressure fuel pump and DI.
It sounds good up in the rev range as well. And that's on a cold engine. I'd guess it'd quiet down a tad once more too. Enjoy the motor. They'll run 300,000 miles pretty easily. Tons floating around with that miles. I have a little over 250,000 miles on my 1KZ.
