i found its the worst when there is a small load on engine - idling in gear, idling with AC on. but drives fine. it changes with different engine oils too. i asked a mechanic to look at it and he was like sound seems to be coming from valve and headers but the car drives fine. he basically said the car drives fine, no need to spend money looking for small wear and tear. it took a while before I got over my paranoia about this :cool:
