Is this the noise that others are hearing and recommend don't worry? Assuming these cars didn't do this new...we can fix them.

Yes, pretty much. Hard to tell in the video.

How long are people having this start up rattle? I was having it for about a second, and then it goes away.

Mine is doing the same thing too. Does anyone know if this is something that needs to be fixed, or is it just a character of the engine?

Check the two exhaust heat shields. They can rattle on start up.

I don't know if it was a "seat of my pants" experience... but when recently I replaced the pressure relief valve with the updated/upgraded part I swear that rattle was recognizably less audible, and has continued to be so. I drive the car about 3 times a month (for now).

Someone tell me I'm hearing things, or second my assumption.

Thank you.

Yes it needs to be fixed, that's why Porsche reengineered the part in 2001 or 2002 with a integral spring to pre-tension the chain. there is a TSB that explains the issue & new part number. If you buy a new one from a dealer for a older Porsche you may get the original non-updated part.
