I really do think it's one or both of the pushrods on the left side that is rattling at a certain frequency (equal to 3000rpm).
Then you'd hear it directly when you hold a screwdriver between your ear and the tube, like a stethoscope, when you have a friend run the engine up to 3000 RPM.
No guessing there !
