I'm back with the knocking engine problem that I see has gotten a bit louder and is always present after the engine warms up(town), only noticeable in idle, I'm also posting a recent video on YouTube for a better perception https://www.youtube.com/shorts/zQEwKuHnDds
What do you think it could be and where could it be located?
One of the mechanics suspects it could be an noisy actuator from the fuel line. I don't know if such a thing(with that name) exists in the supply line!? From what I can see on the Honda diagrams, on the supply line there would only be this: "36450-MCA-A62 Valve ASSY., ex. Air Injection" and "36162-PLC-003 Valve, Purge Control Solenoid", as mechano-electrical parts that could generate noises during operation if there are faulty.
What do you think, could that knock noise come from one of these assemblies of the fuel line or, the problem is from the engine?
Has anyone else knows or experienced something like this, does anyone have these low-frequency knocking noises(Tok,Tok) and how worrying are them? What should I do and where should I look for the cause? I've been struggling with these since spring and no one has found their cause and location with certainty. Much appreciated any ideea, suspicion, comment etc.
