Mine seems to come and go also. After PM'ing some gearheads on here and elsewhere I have resigned it to valvetrain noise. Since the engine is meant to run at such high rev's, at lower rpm the valve lash has not been fully taken up by the hydraulic lifters yet, thus the noise. That is to say there is some play in the system until the engine is really humming. A bearing noise would be more of a clunk or knock, and would get worse as time went on.
