Here is the weirdest thing: when started ice cold, this engine is WHISPER quiet. There are no noises whatsoever. After about a minute of idling, it starts ticking. There is no way this is a case of the oil viscosity changing, as the engine has not run long enough to heat the oil significantly.
Believe me, I have had some very top-notch engine builders listen to this Element engine, and they are all equally stumped. One guy suggested that maybe the noise is in the VTEC system somewhere, although I have changed the filters in there and nothing looked abnormal.
Here is a post I did on the Honda Element forum, for those that are interested.

I will ask again, when your engine is at operating temp does the noise go away? Because my engine is also whisper quiet for a minute UNTIL IT IDLES DOWN then the piston slap begins. It sounds similar to your video, BUT it goes away once warmed up. And I dont mean when the coolant warms up, I mean after a good 10 minutes of driving or more.
Here is exactly how this goes. Stone cold engine gets fired up and there is no noise whatsoever. When it idles down, it begins to tick.
Once it starts ticking, it is there for good. Five minutes or five hours of driving, the ticking remains.
Got it, so its certainly not piston slap.
