Maybe you have a piston slap, sort of like this Subaru
‘17 Honda Civic - how does this oil look?

Frequency increases with rpm increasing, and completely disappears after 1,200-1,300 rpm. But it sounds the same as far as the “loudness” goes
My Honda pilot has piston slap I believe. It goes away once the car is to operating temp (been like that since brand new, compared to a few brand new pilots and they all did the same).
So, something’s changed since yesterday. I’ve changed the oil, my tank was empty and I refilled with premium gas. Drove another 100 miles during the day, came back home and I swear couldn’t hear the knock. Wrote it off as being tired and my ears just worn out listening to it. This morning took the kids to school (1mile drive), knock is present. Ran to store and came back (another 7-8 miles), and it’s gone again (see video below). This doesn’t make sense
If the knock is intermittent, perhaps note the outside temp and whether the engine is warmed up or cold, but it could be one of the accessories or timing chain related, perhaps the tensioner.
Sounds like D.I. injector rail noise from here. Sometimes on lightly run engines you can get carbon and ash buildup in the quench area on a zero deck design this can cause noise - but usually at mid rpm and up.
I thought it was NOT intermittent (at least ever since I’ve definitively noticed it). One thing I just remembered that I’ve originally left out, is that roughly 10-12k miles back last year, I was sitting in the car in the parking lot waiting for my kid’s swim practice, and noticing this very noise/knock. It wasn’t a perfect environment to chase it so I brushed it off and honestly totally forgot about it. Up until a month ago or so when I was changing my transmission fluid..
You can also have VVT racket which can mimic other more familiar engine trouble noises.
These new engines are surely not quiet like a 350 SBC or 429 L/M Lima 385

These engines are very “noisy” by design. My first Lada I’ve learned how to drive a car had quieter engine.
I’m at the point where I’m not sure how to proceed . I’ve taken it to a mechanic that states it’s the high pressure fuel pump and they get a lot of these. Take it back and have them do the valves adjustment and look at the cams? Take the oil pan off and inspect the bearings? Or just continue driving it until the problem manifests itself in a dramatic fashion and then deal with it?
I have an excessive noise concern on overrun on my Ford Di 2.0L. Much noisier than yours - though it's hard to compare "in person" to a recording. It knocks hard when you rev it then let off the throttle.
If I recorded that noise, you would be aghast. I am still under the engine warranty for a couple more years, so I don't worry unless I might get stranded on an interstate with no breakdown lane.
Funny aside. I Had heard loose flex plate bolt cause a knock, and a knock racket and on an old AMC was due to a cracked flex plate.
But you have an MT and a flywheel.
Does the noise go away when the clutch is depressed? Just to rule out layshaft rattle?
Good luck, Maybe just keep driving. What filter do you use, by the way?
Yes, it’s still there with the clutch pedal depressed. Transmission has it’s own “idle running sounds” but at least it doesn’t change and I’m used to it.
I’ve been using Fram Ultra since around 10k miles. Usually run it 2-3 OCI since I change oil every 3-4k miles (after I finished “extended” runs with Amsoil at around 40k miles)

Honestly, I have the 1.5 DI non turbu version of your engine and it sounds very similar (although a bit quieter).
As long as you are changing the oil more frequently than the oil life monitor suggests, you'll be fine.
Just looked at my maintenance records, 18 oil changes, all done by myself. Not once I’ve changed it based on the MM. three ~7k “extended” intervals with Amsoil (all highway miles), and the rest 3-4k miles. 5w30 since 10k
At the risk of suffering the pitchfork and citronella torch crew, I know the Honda filter is a blue fram service part- a bit better than a subaru blue fram oe a Extra guard. But On our Subarus they never tolerated the USA service part (blue fram or an Ultra) We got rid of odd and excessive noise running something "other than". Can't explain the mechanism - only the result.
We had a 2018. The injectors themselves on these engines is quite loud and happy. I don’t recall the HPFP sound on it, but the one on my ford sounds very similar to a diesel when it’s low rpm and cold. The 1.5t in our civic got beat pretty hard and handled it admirably well. I’d have another.
I might give a Honda filter a try, but I history doubt filter is the culprit
It’s a great car for the money indeed. Had 0 issues with it so far, only 1visit to the dealer at around 5k mark for a 3-way connector recall. I’m not driving it too hard, but don’t baby either. My wife hates it, I love it. Balance is the key
