I couldn't hear anything I would consider unusual. You could check valve lash. I would suspect it's just a tiny exhaust leak when everything is really cold and contracted. If you're not changing oil regularly it may not have the same viscosity. That's mostly a problem for hydraulic tappets, which I don't think this car has.
