  1. A 1.0 bar wastegate actuator has recently become available for the 996TT. It's being sold as an upgrade for cars that have already been chipped - but I've been thinking... The stock ECM measures boost and controls the wastegate actuator through a solenoid. Both the spring in the actuator and the solenoid via ECM and MAF open at 0.7bar. The idea is there may be slightly improved response if both the ECM and wastegate are set to match at 1.0bar. This seems especially the case if there are some leaks in the solenoid or vacuum lines, since what does the actuator's setting matter when it's the so
  2. Question. Are the tubes normally holding oil back in the engine? If you were to take the tubes out, without first having drained the engine of oil, would oil pour out the spark plug holes?
  3. My Boxster is a 1998. I'm having some trouble with my door locks. On the passenger side the lock turns, but doesn't unlock the doors. Is this a typical problem? On the driver side the lock turns (but it's really sticky), I'm worried it's going to break. I suppose I will have to open up the door panels and see what's going on in there. As I understand it, the dealer only sells the lock cylinder part - I hope that's all that's broken. It would be nice to add the factory remote unlock feature on the car -- I don't have it! I imagine that wouldn't be impossible, since the locks alread
  4. I took out my IACV for cleaning (about 80k miles). How exactly is the flap supposed to sit when its resting and removed from the car? The flap can easily open and close completely with my finger, but at rest it sits with a 1/8" air gap. That seems a little odd to me for a normal resting state. I would have expected that it should stay completely closed. I cleaned it, but I still a bit of an idle problem (dipping so low nearly stalling) when the AC comes on. Do I need a new IACV?
  5. Fellow Porsche people, I'm looking around for a second Porsche. Specifically a pre-loved Cayman S. One of the dealers I visited mentioned that during the used car inspection they check "that the previous owner hasn't exceeded the redline more than three times". I have no doubt that the Porsche diagnostic tool/computer can read that kind of information out from the engine computer... but this seems strange on so many levels. Can anyone confirm that the PST2 (diagnostic tool) can really read out such things? Is there also tracking on max GForces I wonder? Do dealers really inspect these
  6. I understand the value in replacing the plastic window with glass. But I question how much long term benifit there is. I've been looking at my top more closely - while sitting in the seat with the top up- I've noticed some serious wear of the inside of the top near where the mechanisms must rub. So - what is the point of making the rear window last forever if the cloth doesn't and pretty much blows out about the same time? Do you guys know the wear I'm talking about? Need pics? Also once you develop a couple of small 1/4" cracks in the rear window radiating from the stitches, how long
  7. Do what you feel comfortable with - you'll be under the thing. ;) I had removed the access panel anyway since I also did the serpentine belt. It wasn't really useful during the mount job, other than perhaps adding more light to the area while I was working. The repaired mount works wonderfully. I was considering a new mount, but then I started to think that since my main issue was that the insert slid, the same could happen again with a new mount. Seems like that's addressed by the new bolt I installed through the housing and the insert ring. There certainly won't be any cracki
  8. I'm a little confused here - would you help me out? I changed out my plugs this weekend. Dunno how much millage was on those things, but looking at the electrodes, they were sure ovaled out. This combined with the cleaning of the throttle body has really improved my idle. Anyway, while I was in there I noticed the plug boots looked a little funny - a couple of them were cracked around the bolt area. Is this a big deal? Are these just plug boots - should be thinking about changing out these boots and wires as well for this service interval? Or does this car have six individual coil p
  9. I had no problem using just my 2 1/2 ton floor jack under the engine. No special equipment necessary. I left the standard cup on the jack and lifted/lowered directly under the engine that was just in front of the oil pan. Obviously you'll want to jack near the front of the engine where the mount is, and this tends to get in the way a bit while you're working there. Don't forget you can break loose all the bolts before you bring the jack in! I'd highly recommend that strategy since it'll give you more room to work. Contrary to the DIY listed here, I found that my mount only had three bol
  10. 986jim- so like this then? ;) i had the bushing slide in the mount too (just like in toolpant's picture), so i hammered it flush, then appled a big 10mm bolt and nut through the thing before the flexane.
  11. Regarding the idle air control valve. When you have it out for cleaning, how exactly is the flap supposed to sit? The flap can easily open and close completely with my finger, but rests with a 1/8" air gap. That seems a little odd to me for a normal resting state. Don't tell me after all this cleaning I'll still have an idle problem with the AC on and need to try again with a new IACV? Thanks! PS: here are some before-cleaning pictures of my throttle body. This is a 98 Boxster with 73k miles. I suspect the throttle had never been cleaned.
  12. So I'm about to get started changing out my front engine mount. I'd mentioned in a previous post that I had the rumble when turning left and over bumps. Today, I get under my car and I'm looking everything over really well in preparation. And what the heck :eek: - I noticed the right rear lower control arm is pretty messed up! Here is the left side, and the right in comparison. The right side is bent, even cracked a bit. I'm not the original owner, did someone fishtail and nail a curb here or what? Could this be the source of my rumble? Should I be changing out some other arms? Ever
  13. Hey that how to looks great. I suspect my mount is blown (I have a rumble on turns to the left) and over bumpy roads. How do I know for certain if it's my mount that's blown or a rear arm? I have about 70k miles. Thanks!
