It has been pretty cold here in Alaska lately, but I can't imagine what else would start ticking as a loose lifter sounds. With roller tappets and synthetic oil, how could it loosen up so soon, unless it was not tightened properly in Japan? Anyone know if they are robotically adjusted on the assembly line or man-ually? What do you think? Is this normal?
I have noticed in pretty much all of my hondas (at least the 4 cyl models) that as they get older you will hear a bit more valvetrain noise, even if you adjust them regularly. I'm not sure why they're so danged quiet when new but eventually you hear more of a "tappety" sound.
