On startup, the oil has all seeped back to wherever it sits when the engine is at rest. For the first few revolutions, the lifters won't be completely filled with oil, so you may get a clattering. It doesn't mean there's anything wrong, and the lifters will quickly be up-to-pressure (especially in these engines with the dry sump). It's only a concern if it continues for an extended period.

I am driving my GT3 every single day to my office and to the gym so all the noises it creates already aware but this one coming from the engine compartment is after owning the car for more than 6 months and more than 7000KM. the car now is 14000KM and 10 months old

And let's not forget about the smells. From cosmoline, to road debris on the exhaust and, in my case, to leaked coolant evaporating on the warm engine.

Hey almeena, it happens quite randomly, i bought my car new last year... It had been discussed hear before and I hadn't got it yet which I thought was strange. One morning after 3 months (3000 km or so) the machine gun rattle occurred. Now i may hear it once every couple of months or so... Nothing to worry about.

For the first few weeks after I got my 997.1 I was amazed at all unique sounds it made. All the boings, rattles and occasional puff made me very attentive at first but now every few weeks when I hop in it I can't wait to hear them!
