yes, that was one of the first (of many) things i checked. i can have someone else start the car while i am looking both under the hood and from underneath the car, i can hear the sound clearly but am unable to pinpoint where it comes from. i wonder if it's somewhere in the engine. i do need a valve adjustment, as there is a loud tapping when the engine is first started. Any chance that could be related? Also, if hearing the sound would help, let me know and I could find a place online to post it

yes, it could be a lifter noise or a noise from the bottom of the motor. you need to at least get someone at a shop to hear it to lead you in the right direction, then get back to us.
