  1. An FYI, it turned out that the air/oil separator needed to be replaced. The key thing to look for, when the whistle is occurring, you are unable to remove the oil fill cap due to high vacuum. Total price at an independent was slightly over $500.
  2. My 2000 Boxster (non-S) 5-speed suddenly started making a constant frequency or constant pitch whistle. It has occurred twice, and in both instances the engine was fully warmed up, with the noise staring after about 20 miles of driving. In many instances of driving similar distances it does not occur. From the sound, and standing exterior to the car it is very likely to be coming from the engine compartment but from outside the vehicle it seems to be similar volume regardless of side. It goes away with light throttle. As I said it is a constant pitch regardless of engine speed and occurs at idle. Thoughts very much appreciated.
  3. My 2000 Boxster 5-speed suddenly started making a whine or whistle. It seems to be dominant from the drivers side of the vehicle but I'm not 100% certain of that. My drive was with drivers side window down and every time a car passed in the other direction the noise significantly increased. It goes away with light throttle. With foot off the throttle that is when it is most noticeable. It is a constant pitch regardless of engine speed. Maybe, and I emphasize maybe, I have had a quick flash of a dashboard light, perhaps brake fluid or ABS, but just a fraction of a second and I was unable to identity positively which light flashed. Thoughts?
  4. In doing my project yesterday I did notice that in removing the (4) bolts mentioned, they were tightened not much more than hand tight. "Snug" would be a good term. I'm also not sure what material they may screw into. It may or may not be metal but even if some form of a metal bushing, the bushing is likely mounted to a non-metal portion of the steering wheel. [Edit] I found that the Bentley manual specifies 5 #-ft (6.8 Nm) for the (4) bolts. I also found a copy of the Porsche Technical manual and at least for MY2000 the torgue for the T30 Torx screws is specified as 7.5 #-ft (10.2 Nm). There was no indication of any thread locking material on (3) of the bolts, but one had some residual of a red material. There is a red Loctite but it is for high strength high temperature applications. When I replaced my bolts I simply used clear nail polish. I also used clear nail polish for the (2) bolts that hold the air bag on. As a mechanical engineer, I'm reluctant to use blue Loctite on small fasteners, especially when they are recessed into a blind hole. Strip the head on one (as someone mentioned they did) and you have a serious project on your hands.
  5. The MY 2000 Boxster did get an improved top relay, about mid to late spring of 2000. My original had failed, of all things in the Porsche dealer parking lot while attending a Porsche Club meeting. I remember being told that I was getting an improved relay and as I recall it had a blue dot on the top of the case. I'm sure if you ordered a relay today you would get the latest version.
  6. Well it turns out, IMO, my issue is the water pump and not the IMS bearing but thanks to all for your feedback. I was using a stethoscope to check various idler pullers, alternator, etc. and noticed a distinct wobble to the water pump pulley. Lucky me, as I'm observing the wobble, it stopped for a period of 30 seconds (more or less), and so did the erratic noise I was getting. This behavior was observed on a couple more occasions, and the noise is definitely related to a water pump pully wobble that can be visually observed. I had already opened up the oil filter and it is clean; I can't get so much a filing of any type on my magnet. Also, based on the comments at http://986forum.com/forums/general-discussions/46267-single-row-vs-double-row-bearings.html it would appear I have the double row bearing based on the "Y" in the engine serial number which indicates the engine assembly occured in 1998. JFP in PA, if I double posted, and I assume I did and hence your comment, I'm sorry. I do remember that once I had prepared my question and clicked submit, I seemed to wait quite an extended period of time and hence hit the submit button again. The 2nd time I got a progress bar, the 1st time I do not recall the progress bar.
  7. 2000 Boxster, 2.7 liter, 5 speed. I'm the sole owner and no work has been done that would ever necessitate an engine change. The engine number off a Porsche issued Certificate of Authenicity (CA) is 65Y06546 and the boss at the right rear of the engine likely agrees with that. I say likely becuase I can't make out one digit but all the others agree and are the same sequence. Build date, again based on the CA is 12/13/1999. At the LN Engineering the IMS bearing retrofit site states engines up to M65112851 are likely dual row IMS bearing and after that single row. That number, at least to me seems to be a totally different format. Anyone have any insight what type bearing I have. I'm thinking of doing the LN/IMS mod in the near future and would like to order the proper kit in advance.. John from PA
