thats the thousand dollar question
i have to be honest, to this date, i have no idea which side its coming.
i bought 2 stethoscopes so i could left ear = passenger side vanos, right ear = drivers side vanos the startup sequence but got in an argument with my gf both nights i had everything ready (remember, gotta wait 6+ hours at least to hear the noise etc etc etc) so i have yet to do this.
the one time i had my head under the hood, with the intake manifold removed, the noise sounded like it was coming from the drivers side valve area. although, there were so many noises at once, i would take that with a serious grain of salt.
if you (or anyone else for that matter) get this done via warranty or on their own, let me know the procedure they used to diagnose what side it was coming from
