  1. You can get a set of small "ez out" hex bits, one of which should fit tightly into the bolt head while rotating counter clockwise, which will loosen the stripped fastener. Amazon and others sell them (Amazon screw/bolt extractor set)

  2. The headlights look fine to me.... people obsessing over headlights and BS like that are what makes the 996TT still one of the best cars out there, pound-for-pound, dollar-for-dollar

  3. Welcome to RennTech Anyone that has spent any time running back to back dyno test of various hardware on a single vehicle would tell you the +/-3 HP run to run should be considered experimental error more than proof of anything, as well as rarely reproducible; and that dyno results on totally different brands of vehicles are not comparable. But it is your car and your money, and if you are happy with your choice of air filters, enjoy.

  4. Perhaps but SD slot is in back so it's awkward to switch it out. I think better possibility may be similar to audi or Lamborghini maps. I think first thing is to see if it can be copied so one can have archive

  5. To answer my own post - a while after posting, I found a local transmission shop that had the smarts to figure out the problem. The guts of my transfer case was made by Borg Warner according to the transmission shop. I found replacement seals and belt at NP 235 Transfer Case Kits | Cobra Transmission COBRATRANSMISSION.COM Are you looking for the best NP 235 Transfer Case Kits for sale? Shop all NP 235 Transfer Case parts today at Cobra Transmission. The noise I was hearing was due to the belt stretching out over the years, and hitting the inside

  6. As I have said before "if ain't broke...". As well, you might want to check the price and labor of replacing just the troublesome one.

  7. Thanks JFP, cleaned those out this spring and they were a mess. Not real active on this forum, mainly a lurker, but really appreciate your info you provide here and elsewhere. I just completed a full suspension refresh, and have spent way more than I paid for the car restoring it to her glory, but runs and drives like a new one and plan to keep it for a long time.

  10. Hi all, Hoping to provide some clarity on replacing the crankshaft position sensor on a 986 WITH Tiptronic transmission as I have not seen (or was unable to find) any good/clear pictures of the process to find the sensor. As I found out, it is hiding well behind the plug/receptacle for the Oxygen sensor on the right side of the vehicle. I read all kinds of guides pointing me to the correct general location, but they all pretty much said it was obvious and I knew exactly what I was looking for. I spent well over an hour searching because I could not see it, and found out that on a Tiptr

  11. I would replace with a new PCCM plus. I just completed mine. It is a great upgrade over your current PCM. Cost is about $1300.

  14. I don't know where you got your price quote, but you can buy the Stant pressure tester (STA 12270) for $72.38 on Amazon, or $69.78 at ToolTopia. As for Porsche adaptors, there are two; 12016 will test the vehicle and sells for about $40; 12017 will test the cooling system cap, and sells for about $10. I have two of the Stant testers, and an entire case full of adaptors to fit just about anything, and I didn't pay anywhere near $500 for everything.......................

  15. :welcome: Start by checking the fuses Also, sometimes when there is a short (like with your visor) it corrupts the memory in the control unit. In these cases the control unit needs to be re-programmed with a Porsche PIWIS tester.
