From other forums, it seems like the vvt-i clatter is a constant. It doesn't go away after the engine warms up. Besides, wouldn't that cam/vvt-i show up in my oil analysis? If you know otherwise, I'd like to hear more.
Did you have the cams and VVTi replaced per the TSB?
Cam/VVti will not show up in a UOA. Loose tolerance will function fine with a little noise.
