Recently changed the oil on my GX. After I noticed a tick noise when accelerating at lower speeds. Not a constant tick, more sporadic but I can get it to make the noise when I accelerate. Does not make the tick noise when I initially start car and drive. Engine must warm up.

Used Mobil one oil like usual and the oil level and filter is good.

Engine runs smooth and I do not have any check engine lights, I just hear the noise.

could this be the lifters or timing chain tensioner?

has Any experiences this issue?

attached is a video

I don't here any tick in the video, just wind noise.

Doesn't sound like timing chain at all, more like something is rattling but hard to make it out from the vid.

Make sure that it’s 2013 gx460 or 2023gx460? I have same issue on my 2023gx460 after first oil change 10k. I went back to Lexus service and they rechang oil one more time and said keep diving couple days that’s see issue solved or not. But the noise still there form the bottom of engine. So I think I need to back to Lexus service again that’s see anything we can find out.
