My 2000 Boxster S has developed a rattling/clanking noise that I cannot seem to figure out. It is coming from the front of the engine area, but I have checked all the pulleys, compressor, pump, and alternator and all seem fine! When you run the engine with out the drive belt, the noise still persists as usual. Is the thermostat going bad?

Any ideas would be appreciated!
