997.2 Manual Tea Kettle sound?
Hi Everyone.
I'm a fairly new member and purchased my car from the forums here back in January. I've had a great experience with my car but unfortunately I'm experiencing my first mechanical issue.
I went for a longer drive than normal over the weekend and as the car got up to temperature, it started to make a sound like a tea kettle. It was audible in low RPMs in gears 1-3 and would increased in frequency until around 4k RPMs and it either stopped or I didn't hear it over my newly installed Fisters... However, it would go away as soon as I pressed on the clutch. I actually happened to pull up next to another 997 and he said he heard it too. I stopped at a store for 15minutes and it seemed to almost go away completely on the way home.
So, I made an appointment to bring it in on Wednesday but I decided to drive around today to see if I could reproduce the sound. It was around 85 degrees in SoCal today and I drove it hard and it made absolutely no noises like before and I was thinking I should cancel my appointment. But then about an hour later, I picked up the kids from school a mile away and the sound was so bad I had to pull over and I barely made it home. But it still completely went away when I pressed in the clutch.
Here's a video of when I got home, which admittedly doesn't sound too bad, but you can hear the chirping even when idling:
Any thoughts on what this is? I did a lot of searching and some point to a TSB on a steering fluid reservoir valve, but those seemed to be mostly on 996s or GT2s. It just seems strange that it's so intermittent.
I'm bringing it in a few days, but I'm wondering if it'll make the sound then or if I should even drive it to the shop.
Thanks for your help!

So if it goes away completely when you push in the clutch, pretty sure it's not anything in your engine. So that's relatively good news, I'd think.
Not an expert, but from a quick search could be your clutch pilot bearing?

Or what my dad and grandpa called the "throw out bearing" when I was a kid?
I try to lengthen the life of those things by never sitting with the clutch pedal depressed, but rather choose neutral and wait until it's time to go.
Regardless of the correct nomenclature or component names, if depressing the clutch quietens things, I would suspect some rotating component of the clutch assembly?

Thanks, guys! That all makes sense and sounds likely.
It seems like a cheap part but one that's hard to get to. Is it something they can replace relatively easily or is it worth it to replace the clutch while they're in there? It feels fine, but my car does have 63k miles on it and I don't think it's been replaced before.

So if it's making noise when you PUSH the clutch pedal, that's the throwout bearing. I had a car that did that, when you pushed the clutch you could hear the bearing loudly spin down. He's got the opposite problem, which is potentially the pilot bearing, a different part. It apparently supports the transmission input shaft.
But if I'm pulling the transmission, it's getting all new whatchmacallits.

So, I brought my car in and ended up getting it towed there as the sound got worse and became more of a chirping noise that happened constantly. It turns out that the tensioner bolt snapped off and I now know exactly when that must've happened. Luckily, I was going less than 5mph and was close to home. They got the bolt out and are going to replace some pulleys and belts tomorrow and they don't believe there was any other damage.
Thanks again to all of you who offered some help. I'm not capable of doing the repairs myself, but it helped put my mind at ease, at least for a little while! I definitely experienced some of the highs and lows of owning a Porsche today! I couldn't help but think of how awesome it looked as I followed the tow truck to the shop, then got myself worked up that there could be some sort of engine damage and was unable to concentrate on anything else...
Anyhow, if anyone else finds this and has this sort of issue, add this to the list of things to check.
