Trying to identify the source of a rattling coming from my 2000 Land Cruiser (USA, 2UZ-FE). It is only really at idle, and actually usually instantly stops if I touch the throttle at all. It is very inconsistent, appearing at random times seemingly unrelated to temperature, ambient or engine.
I would describe it as what you would expect tapping on a hollow pipe/tube ~tens of times a second. In the cab it is sorta muted and sounds like it would be coming up from vents. But the frequency of taps seems too low to me to be from something being struck by a fan and is unrelated to the a/c or heat being on. Tough to search for related threads by describing the sound, the "best" seems like it might be heat shielding on the cats, but I'm not sure.
Here is a video I managed to snag, it sounds a lot louder with both the window open and the wall next to me reflecting the sound. Any insight is greatly appreciated, Thanks!
