Replace your tensioners.
What oil is in there? Switch to 10/40 or 15/50.
See what happens.

I bought a 03 996 with 67K well cared for miles. Car had been driven only about 5K miles in the previous 5 years prior to purchase. I would get some chatter at cold start and was concerned about how I would solve it. I did 2 things....
A few hundred miles prior to an oil change, I added Marvel Mystery oil to the the car....maybe a pint or so, and drove the car for a few hours.
Also did the OPRV while I was changing the oil.
I haven't heard the rattle since. Been about a year.
