Of late I've noticed some "valve clatter" when it's cold. Quiets down pretty much after reaching operating temperature. Took it in to my mechanic (non-Honda shop) for oil change and tire rotation and asked him to check it.
Owners manual specifies "valve clearance adjustment" ONLY WHEN NOISE IS EXCESSIVE or verbiage to that effect. Mechanic said he noted a bit of noise but none of the service books make mention of valve adjustment on the V6's - only on the 4 cylinder.
Nothing I've seen in the various forum threads contradict this.
Am I missing something?
