Hmmm...Your "whining sound" could be a pile of things but I would suspect a vacuum leak...especially if the vacuum lines are original. For that matter you should seriously think about replacing all the rubber lines including fuel, vacumm and cooling.


The rattling is possibly a loose heatshield on the exhaust manifold. The welds break loose over time and can make that annoying sound.
