Sounds like you may have some dirty lifters... Porsche's extended oil service intervals breed these types of gripes because the lifters collect crud and then become seized and they start to tick..

I just repaired an engine with this issue two weeks ago, 12 of the lifters were seized!

if yours aren't bad yet some Marvel Mystery oil in the engine oil could free them up... Its a longshot but can solve the problem.

It also might be a very small exhaust leak.

Wiggie18,
Your dealership is on crack... People need to realize that the dealers know little to nothing about the internals of these engines- they don't build them and don't repair anything more than a timing chain, if that!

I have a Porsche Factory trained tech on my staff who had never gone into one of these engines internally until his first day on the job under my roof.
I hear all sorts of wild assed stories and diagnosis from dealerships, the majority of which are totally off base.
