You can hear it pretty clearly at starting at this timestamp. |
You can get a cheap "Mechanic's Stethoscope" at Harbor Freight that will allow you to listen to individual engine components and isolate just where a particular noise is emanating from. You can touch the tubular probe to a particular component and hear the difference between that location and others.
You can do things like touch each injector and hear them to find a noisy one, place the probe against the intake and exhaust manifold openings and hear any difference between one and the other valves opening and closing.
You can use the same technique to listen to the various pulleys driven by the serpentine belt to find a noisy accessory's bearing noise such as an alternator or AC compressor, as well. The Stethoscope only cost 3 or 4$ last time I bought one.
