  1. Just an update incase anyone else has this issue. I ended up pulling off both mufflers, and took a closer look. The passenger side one was missing a weld on top of one of the pipes. It looks like it was never actually welded from the factory. And both mufflers had identical cracks on the support braces. These are the braces are that furthest from view, so I hadn't noticed them without taking the muffler off. I took the mufflers to a welding shop and had them weld the straps and non welded pipe. I put them back on, and I think that may have solved the issue.
  2. Thanks for the heads up White987S, will have a look.
  3. In case anyone else has a similar issue, it looks like this is due to a broken flap in the PSE or a crack somewhere in the right side of the exhaust. If it's the flap, I think the only option is to replace it, right?
  4. Cars in the shop, but think that was it. The clutch went out, so it's getting replaced. I have a feeling thats what the noise was.
  5. Is there anything in the clutch that could make that noise? When the clutch is engaged, or disengaged.
  6. Awesome, thanks for all the suggestions! will add that to the list to check. Yep, I have PSE.
  7. Nope, doesn't sound like any of those. Maintenance history is good, just had one about 4k ago, with new water pump, pulleys, and belt. It sounds like something is loose under the car, or at one of the wheels. Def a thin metal sound. I'm going to take a look at the break calibers, wheel joints, under belly, and make sure everything is torqued.
  8. I've got a strange noise when I'm in slow traffic. It's the same sound you get when driving over a manhole, sounds like this video: http://www.brentwoodgazette.co.uk/VIDEO-noisiest-manhole-cover-Essex/story-19014831-detail/story.html It happens when slowly increasing acceleration in first gear, and appears for only a second or two. It also appears when reversing slowly. As well as when turning in gear, with no power on the accelerator. And when breaking while car is moving really slowly, while in neutral. I can only hear it with the windows down. And only happens on occasion. And as far as I can tell, it's coming from the back of the car. It's also hard to replicate as it doesn't happen every time. Anyone else experience this or ideas? Update: I am able to reproduce it when coming to a stop, then starting again. Happens both when slowing down and accelerating. Both when my foot on and off the clutch, or in neutral. Also happens with my foot both on and off the brake. Thanks! 2006 997S
  9. Thanks for the link! Alternator seems fine when testing it. Checked all the brackets, they all seem fine. I tried using the Engine Ear, no luck so far. I pulled the orange plug to turn the pse on all the time, and I don't think I hear the noise anymore. I definitely heard it when it was turned on via the PSE button and when off. I think next up I'll check all the heat shields. As far as I can tell, it seems to only happen at 3900 - 4100 in each gear. I wonder if something is just changing over in that rev range? Also, any idea what is disabled when the orange PSE plug is pulled? For example, I wonder if it's bypassing something that comes into play around that rev range. The engine ear did help track down an interior noise though, so def a useful tool to have.
  10. Thank you both.. I order that tool, so I'll give that a shot once it comes. All the other pulleys seemed fine when tested. I'm a little hesitant to run the engine with the belt off, since I need to get it above 4000 to hear the noise, and the engine heats up quickly.. I don't want to cause any damage, but I think I'll give that a shot soon if I still can't find the issue. I started looking around at the clamps too and tightened them all up, just to make sure the exhaust isn't the culprit. Does anyone know where I could fine a diagram that lists all the exhaust clamps? I want to check to make sure there are no hair line cracks in the cramps that could be causing the noise. Thanks a lot!!
  11. So I replaced the upper pulley and belt. The noise was gone when going above 4000 rpm. Took it for a drive and the noise appeared only when decelerating down past 4000. Then after driving for a while it came back both accelerating over 4000 rpm and decelerating. Any ideas? Same noise with ac on and off.
  12. Just a quick update.. So I took the belt off and checked all the pulleys. The tensioner and bottom idler pulley seem fine, and both act exactly the same. The top pulley seems to spin a bit too freely. And the AC compressor pulley has the slightest little bit of play. So my plan is to replace the top idler pulley (think it needs it either way) and belt, and see if that fixes the issue. If that doesn't, then I'll try running it above 4,000 RPM with the AC on and see if the noise is different/gone... and go from there.
  13. Thanks all! I haven't had a ton of time to look at it recently, but I did do a quick noise test with someone else revving it. I think it's coming from the alternator pulley... but I'll keep troubleshooting. Is it safe to do the following? 1. Pull out the airbox 2. Take of the belt 3. Rev the engine without the belt on I want to verify the noise is coming from the pulley/belt.. but want to make sure that doing this test won't damage anything? Thanks again for all your help!
  14. The belt looks ok to me. It looks like it was replaced at the last service about 6 months ago. Any tips for what I should look for visually on the pulleys. The plastic is not completely flat and has a slight ridge but I'm not sure if that is normal? I may just swing up to the dealer and compare the pulley and see if mine is any different. Thanks a lot for the help!
