I Also have this noise on cold 2025 land cruiser 1958 with 350 miles, it goes away as engine warm up. Sounds like this video.
Anyone found out if this is normal?

 
I would say the noise is normal. If the 25s are making the sound Iโ€™d say itโ€™s normal operating sounds.

Normal. And for me, went away when motor was broken in. As a cautionary tale, someone with the same noise brought their to the dealer, and they were more than happy to take it apart.
 
People reported that the noise disappeared over time. So it can be due to the programing of the engine before xxx miles for break-in. Or new injectors etc are noisy before they physically break-in.
 
It may be "normal" but not ok. Especially longer term.
Start up cold is when the engine experiences significant wear. Probably not detonation. More likely bearing noise. This is a big deal and please keep posting. If mine does it when it gets here i'll pursue this with Toyota to the end. A pre oiler should fix the problem and would be the easy fix and wat to determine oil starvation at start up.
Thx for posting. A potential deal breaker for me.
The video for audio tells nothing. Could be many things and not necessarily the engine.
The fact it goes away after break in in very encouraging.
There is another posting that has a much better audio recording.
If this is ok the dealerships should be able to explain what it is.
