Default Porsche 996 Ticking Noise

I'm new to the world of owning a Porsche and probably a little over paranoid about something going wrong. I have a slight ticking noise, I can always hear it when I'm at a drive through or parked next to something that reverberates my cars noises. I will post a link to youtube of my car. The engine noise kinda drowns it out but you can still hear it (ish). Any thoughts on what it might be would be greatly appreciated.

Your engine sounds fine to me. If you mean bore scoring type of ticking noise, I don't hear it.

I don’t hear anything out of the ordinary.

Yep, just a bit paranoid The "chatter" that your ear is honing in on is the normal valve train noise. If you call this a "tick", wait for a "clank." That'll be your bad noise.

I don't hear anything out of the ordinary, but I also do not know the sound of your car. If you feel there is a new sound, get it looked at.

If it sounds normal to others that definitely makes me feel better

Wished mine sounded that good. You should invest some money and buy/install a water tank cap...

Lol, I had just replaced the water pump and thermostat so I was letting the cooling system burp itself.

She's sitting around 85,000 miles right now. I'm currently running mobile one 0w40 with stp zddp additive in it. Oil pressure has gone up a little bit since the summer weather hit. Usually up around 4 on start up then once she's warm it will sit around 2 at idle and 4-5 on acceleration (depending on how heavy my foot is).

Could be chain rattle, cats, sticky valve.

Get a cheap auto stethoscope to isolate the area.

Is one tailpipe sootier than the other? Any oil consumption? Those are typically the tell tail signs. Does the sound get a bit louder when above idle, say 2500 rpm, or does it get quieter?

Sometime people hear the tank vent solenoid clicking and get worried. Its right above the alternator, get a stethoscope and listen to it and see if that's the noise you"re hearing.

tailpipes are the same. She burned about half a quart over 3,000 miles. It gets noticeably louder and more responsive at a little over 2k rpm, it’s not a gradual change more like flicking a switch

I would recommend borescoping the cylinders on 4-6 with the piston at TDC from the sump. A used oil analysis with emphasis on looking at the aluminum and silicon levels which might indicate scored bores.

Also take a look at the fuel trim values to make sure you don't have bad injectors washing the bores down or a small vac leak causing it to add fuel.
