Default Strange humming/rattling sound when starting

Hey gang, I'm about to purchase an '03 S with 53k miles. When I started the car up I hear this weird humming/rattling noise coming from the engine. I hear it for about 5-10 secs. and then it goes away. Any idea what is causing this ?


TIA

Sounds like chain tensioner...known issue with 'premature' failures/issues causing a rattling/ratcheting sound.

relatively easy replacement...

Any idea what it would cost for replacement?
