Let me start off by saying I am a service adviser by trade and a certified adviser for Honda at the dealership level for 2+ years (been advising for almost a decade for 5 manufacturers).
I know what vtc rattle is and sounds like. This is not that.
It has been happening since brand new (7 miles) and is so light most of the time I question how many "normal" drivers would notice this.
It is not rhythmic and sounds like a knock not a tick and seems to be under valve cover toward passenger side of engine compartment.
Cam chain barely contacting valve cover was another possibility.
Almost sounds light piston slap but Im not so sure.
High pressure fuel pump relief possibly?
Seems like a sound the square cam lobe that operates the pump could make if the pump actuator arm was "bouncing a little" off the cam lobe.
Can I get any input on if anyone else has experienced this?
It hasn't changed or gotten worse and I am changing oil every 5 k miles religiously with the real full synthetic Honda 0w-20. With honda filter.
