Oh God...Weird ticking sound when in neutral...997.2 C2S

Thanks for the responses -
I'm aware of the general valve tick / dfi ticking which I know is part of the 9A1 charm - that's always been there, as expected.
It's the intermittent clicking / tapping that I get when the car's oil temp is just over 200 deg that I'm talking about. Doesn't seem to follow the general rhythm of the motor.
It is a bit hard to hear in the clip (only at the beginning) I uploaded so I'm trying to find a better way to isolate the sound.
Even still, I understand it could be nothing, but it's a bit strange.
BTW - looked through the invoice from Monday's trans oil swap - I had asked for PTX, they said they had it - I looked up the part number and looks like they put Castrol Syntrax 75W-90 in..Part number is 999-917-546-00 which actually shows up as differential oil on google - though I think it's the same stuff as some oem trans fluids. Charged me $63/quart for it. Shifting has actually been worse than before, and I thought PTX just hadn't worked for me.
Following up tomorrow with the shop, very disappointing to say the least.

1) Our manuals specifically state PTX which is a different formulation from Delvac
2) Our dealers treat us like we are dopes and they know better.

If the noise goes away when the clutch is depressed, that probably means it's in the transmission. If it's only when in neutral, I think that means it would be something on the input shaft. Beyond that, I've never been inside the transmission on mine so I don't what could be making that noise. As someone else said, it doesn't sound like a bearing.
If they put in the wrong oil, maybe that's the cause of the noise. Or maybe they got the level wrong and that's causing something weird to happen. I'd make them put PTX in if that's what you paid and asked for. Maybe order it yourself and bring it in. I like it in mine.

I am amazed at how everyone spends tens of thousands of dollars to buy their cars, and then go into cardiac arrest when they hear the slightest noise. But instead of taking immediate action to find out what it is, they spend days posting questions and video here, only to get as many different theories as their are Porsches. If you are really concerned about your car then spend a couple of hundred or so and have a certified Porsche Tech actually see the car and if something is wrong, let them fix it. I know people who died of cancer for the same stupid reasons. They spent hours and hours scouring the internet and talking to their friends. For one of them, by the time they saw a doctor it was too late and they were dead in two weeks.

The car sounds normal to me. I've owned two. Did you change the oil? If so, what grade did you use?
If anything, the valve trail clatter sounds a little pronounced, which isn't indicative of a problem, but only indicative of lighter weight oil.
I'd change your oil to a good, 20w-50, which will quiet the clatter and in my opinion, be better for the engine. If you really want this thread to get real...I highly recommend Joe Gibbs DT 40 as the only acceptable oil. 😂
20w-50 of your choice. Chill out and try to enjoy the car. I totally get the paranoia. It's caused by this damn forum. I once spent 45 minutes, somewhere in Texas, listening intently to my motor while meditating on the engine oil pressure gauge, fearing a scored bore and D chunk failure in my just purchased 997.1. Then, I said 'this is fu$@&8g ridiculous', got in the car and enjoyed the hell out of the next two days of driving the car to Michigan.

Might make the motor quieter temporarily, that is until the internal engine wear causes piston slap, valvetrain noise and other maladies from lack of start up lubrication.
Thx for addressing it/
