2.7L Engine tapping / knocking noise, with video

[Greys]

Vehicle currently has 3,000kms, 2025 XLT w/ 2.7L

First noticed the tapping/ knocking sound in drive-throughs where the echo reflects, and now it can be heard pretty easily from outside the vehicle. Seems to be loudest when warm but not fully warm. This sounds like a worn out 350 with stuck lifters, does anyone else have this sound, is it normal, or am I looking at a service visit? Thanks for any insight. Have heard before and after an oil change, so that did not affect it.

Sounds like it could be the direct injection. My wife's 4Runner sounds the same. Direct injectors tend to be noisy. My Ranger is still quiet but it isn't broken in yet.
For peace of mind I would get it in to the dealership to make sure all is good.

My 2.7 did it too at 1k, Dealer told me that's normal. Now I'm at 6k and it doesn't sound like that any more.

I agree with Ron_TX. I took mine in to the dealer at 1K and they said that was normal. Mine stopped at about 3 or 4K. I also recommend a trip to the dealer for record keeping purposes - just in case...
Might also try a load of Shell V-Power NiTRO+ (or something similar). I do this about every 5th or 6th tank load. Engine is running super smoothe - and I have a lead foot.

If it was me, that truck would be knocking right back to the dealer!

OP, what ever happened? Did it stop making the noise or what did the dealer say?

It's still making the noise, I won't be able to get it into the dealer for another week or two unfortunately. Re: The folks that mentioned fuel and injectors, its been on 93 octane since day one from various suppliers, hasn't had any effect changing brands. I am very familiar with the sound direct injection makes (I actually work in a service department, so I had my own suspicious already, only really posted because I'm mostly curious about other people having the issue before I take it in for service)and it's definitely not direct injection - its much too slow, it would have to be one bad injector, and injectors are more of a tick not a knock similar to a hammer on metal. Once I get it in I will update what the dealer has to say.

Hopefully that's not Uncle Rodney knocking.
