I have the same intermittent ticking noise on my hdj81 with the 1hd-ft. It comes and goes as it pleases. I never recall hearing it when I first got it off the boat. Then I just heard it one day and not the next. Been that way for years. I worried...
I had missed that they had performed crash tests on the 460 for 2023. A member on CL pointed me to them.

Warped rotors are common on these. Mine came (used) with one front rotor warped. I got a vibration with moderate braking but not with light or heavy braking. I replaced the rotors and pads and bedded them in. The brakes work a lot better now!
Couple more notes to add concerning issues after wrapping up the repair.
When all done, I started it up and had traction control, multi-terrain and ABS lights on and a bad belt squeal and faint bearing noise. I had read someone else mention the...
As you work through reassembling everything, just take your time and make sure each step is complete before moving on. Make sure everything is reconnected, all plugs are plugged in, all bolts are present and tight and all hose clamps are on...
One important step I failed to mentioned is in preparing to put the valley plate back on with the new sealant.
Before you do this, take compressed air (or a shop vac or something) and blow all the coolant out of the valley plate mounting holes...
Once the appropriate time for curing has past, you'r ready to start reassembling everything. It's all just reverse order, so read the thread backwards if you're concerning about forgetting a step or can remember if there was another connector...
So, once the coolant transfer tube is lubed up and inserted into the block carefully, making sure there's no kinks, rolls, etc of the o-ring, you're ready to prepare the valley plate with a 3-4 MM bead of FIPG.
**The FIPG has a setup time of 15...
Lift the front edge of the PCV housing up and slide it towards radiator to completely remove. Now's is a good time to swap out the old PCV valve if you bought one. I beleive it was a 19MM wrench, just unscrew old valve and replace with new. No...
The main wiring harness and fuel crossover line that the three (3) connections mate to.
As you can see, I successfully disconnected the driverside L bracket from the wire harness, removed the 10MM bolt from the fuel line crossover and...
The coolant valley plate leak is a potential issue that arises on the GX460 platform (and other 4.6 L V8 1UR-FE engine equipped Toyota's and Lexus's) as the mileage gets to around 100K. A key sign that your GX suffers from this issue is a low...
To put your mind at ease, let me share this with you..
I owned HDJ81 (with 1HDT engine, which is very similar to yours, except for the extra valves).
Shortly after I bought it, it developed very similar kind of ticking, which seemed to come from...
I used to use "toyodiy dot c0m" to access parts drawings, part number and cross-reference but this site is now down for some reason. The site still exist but doesn't accept my login or any other login.
Does any one have a work-around? And if not...
When I had my HDJ81 (1990) with 1HDT, I used regular 10W30 or 15W40 in Canadian summers and 5W40 Synthetic in winter. The Synthetic oil made a big difference in cold weather starting. The engine ran smooth with both oils and didn't burn a drop..
