  1. I don't believe swapping the solenoids did it. The noise also isn't completely gone, but it does happen less often now that I'm out driving the car. Again, when I got the car last year it had barely been driven, then I went at solving the noise without really driving the car. I swapped the solenoids to see if the noise would follow - such as if the solenoid spring was weak or the filter/check-valve under the solenoid was restricting flow. Looking for a possibility of the intake came sprocket to be "clacking" due to lack of pressure or flow.
  2. Slight Update: No definitive solution/cure yet on this noise. I have swapped the cam solenoids and screen/check valves side-to-side. Plus I have driven approx 300 miles in the last week or so. The noise is not completely gone, but is either quieter or non-existent. There are times I've pulled into the garage and idled the car for over a minute with no sound. Occasionally after a drive, the tapping sound is present, but not as loud, sometimes fading out. With the solenoid swap, I can't quite tell if the tap has moved from Left to Right - I've not put the car back on the lift but on the
  3. Haven't really done much in the last few weeks. Just finished with the "infotainment" install and a full-up detail. Our weather and roads are still too bad to drive out anywhere. I am looking to get the car out by the weekend for a run, so I'll post back with an update!
  4. Well, I'll post an update for any new ideas, even though I'm not sure it's solved yet. I'm in the process of changing out the stock headunit for an Android based unit(rooted and sideloaded - ready to go!). As a side note, this is the first Porsche I've worked on, but it's been a good learning project. Many thanks to JFP for the support! Again, this is a 2006 S with 75k miles, not driven much by the previous/original owner in the last year or so. The tapping starts once the engine has dropped to 680rpm, which is not quite up to full operating temperature. It's a single tap around the f
  5. Didn't solve it yet, but I've done a lot of work(never worked on a Porsche motor before, so it's been a learning experience with some help). Found the engine internals to be very clean. I even replaced a side of lifters myself - didn't solve it. Waiting for one part which I should have this weekend. Once fixed I'll post a full report of what I did and what solved it. I'm looking again at chain tensioners at the moment.
  6. That 2005 book is a great source of info!! Wow! Happy to contribute, but now I'm not getting much work done today!
  7. Can someone give us a run-down on how the intake distribution and tuning flaps are controlled on an S model? - What generates the vacuum? (tandem pump?) - How are the vacuum lines routed? - Is there an accumulator? - What actually controls the individual vacuum to the flap valves? Bonus question: How can you tell if the distribution valve is being actuated? Jay. '06 987S.
  8. Added a video of the noise - this is without side and bottom panels, and the lift is about a foot off the ground. http://youtu.be/wAj3zQ2Ly5Q
  9. Yeah, wasn't planning on starting that cam-cover project until I had the tools to hold the cams. Trying to exhaust all other possibilities before pulling the trigger on the tools and time. Looks like an interesting project, just not something I wanted to do but will do it if needed. Spent way too much time already looking at the process. After doing the plugs today, it looks like the cam covers can be removed in-car. Is that possible? It's a little tight, but having it on the lift and panels removed it seems do-able. Jay.
  10. While I'm working on getting the clips uploaded, I found this video which sounds quite like my car: https://www.youtube.com/watch?v=cOCZsBIIXNA I also only have about 50 miles after the oil change and lots of idle time. Running M1 0W40 per the dealer but considering a switch to Edge 5W40 as a trial. Jay.
  11. Changed out the plugs today. Seemed to have even torque all around. Plugs all looked even with just a hint of oil. Found one coil pack having cracks starting, but it's not on the side that seems to have the tapping. Idle is still a little "nervous", but I didn't disconnect the battery or reset anything. The tapping is still there, though. No difference after changing the plugs. I captured a few sound clips and will be posting soon. It really seems to be around the left side, bank 2. With a stethoscope I can still only pinpoint it to that side, possibly towards the front(belt side)
  12. A few additional points: - The frequency seems like it's on 1 cylinder. The tap is approx 4 or 5 Hz. - Going through the Excel sheet of the cam readings, the 2 banks are within 1 or 2 degrees of each other and are well within the 6 degrees nominal from idle to about 3k. - No CEL's or codes. - Once up to op temp, the engine does seem a little rough at idle, as if "out of tune". Going to start a plug change today and clean the MAF. The air filter was dirty and I have a replacement. Jay.
  13. If there was a plug issue, would I see a CEL or other codes? There is no CEL and no stored codes. Planning on starting to change plugs today.
  14. Another tapping noise post.... Picked up an '06 Boxster S at Christmas. Decided on something more modern after racing a '35 MG special, 50's Alfas, and other British. First time with Porsche! There is a tapping noise at hot idle that is driving me nuts trying to find. Here's what's known so far: - Engine has 75k miles and doesn't seem abused. Original owner car. - The noise is not an accessory on the belt. Tested briefly with belt removed. - Updated the oil pressure piston and spring per the TSB. The engine is just before the TSB was issued. - Oil and filter changed recently
