The other thing is that silicone will contaminate the O2 sensor, so one should be very conservative about using it if there's any possibility of silicone being drawn into the combustion chamber and out over the O2 sensors. Sealing the head gasket area with silicone would seem to be in the high risk category for that.

On a recent trip to the Nuerburgring with Mr. Firestone (where I apexed early and popped out of Karrussell at least once - sorry chaps :)) I spotted at least two M3 CSLs, possibly three but they were the same colour and I didn't concentrate on the licence plates. They were fully loaded, with A/C, stereo, HIDs and other trinkets. Also, BMW's road-test CSLs for the German and UK markets, with the sole exception of the launch photo car, have been fitted with A/C, stereo, PDC and so on. That apart, I can confirm that the engine note is subtly different to the M3. Louder and hissier, but in a good way.

Wow, where the hell are you autocrossing. I'm not used to seeing more than about 5 minutes max. Of course, I'd also like to get 120 minutes of track time per day.....90 is about the most you can hope for here w/out going the Panoz/Speedventures/Trackquest/Chin route. > > Bora Lee ------------------------------ Date: Wed, 10 Sep 2003 14:15:06 -0700 From: "Vann" <[EMAIL PROTECTED]> Subject: RE: [uuc] M3 CSL I was at the ring this summer also. I can vouch that the CSLs were fully loaded. I disagree with the comment on the engine note, however. I found the note obnoxiously raspy, like a ricer with a loose heatshield *and* a few washers vibrating inside the muffler. The CSL is an awesome car, but the exhaust alone would be enough to make change it out within a couple hours. - -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Thomas Sent: Wednesday, September 10, 2003 2:04 PM To: [EMAIL PROTECTED] Subject: [uuc] M3 CSL Further to the recent thread about BMW fitting (or not fitting) A/C to its track specials, I thought I'd chime in with this.

The toe was so far out that it wore out the street tires pretty quickly on the inside. Plus it made the car, ummmm, interesting to drive on the street--especially when it was raining. However that was excessive. :) I now have about .5-.75mm of total toe out & the car drives much better on the street. There was no perceptible difference in autocross or track turn-in response. Anyway, the point is that Kumho did a really great job with their Vitcoracer tire, which is only very marginally slower than the Hoosiers at almost half the price. The V700's just aren't as good a tire, although I found it to be a great wet tire. Classic example of the better work you do now, the more people will expect from you later. BTW, if you're doing track events, it's a no brainer that someone will have a pyrometer & will be willing to help you out. For the budget tracker, that's the best thing about rich guys at the track, you can (and I do) borrow almost anything you need. The key point of a pyrometer is that you have to stop as soon as you finish hot laps. I.e., don't go do a cool down lap & then circulate through the paddock then check the tire temp. By that time the face of the tires has reached a very good equilibrium. Instead, come straight into the pits off a hot lap, check the tire temps & then go back out. Always get more than one sample per day.

My impression was that the issue came from the driver's front wheel. Trying to move the wheels did not make me think that it was the wheel bearing, and I did not hear any noises coming from the wheels while driving with the windows down in a narrow, reverbarative space. The issue turned out to be the passenger front wheel bearing. The inner race was torn up, allowing the bearings to comingle. The shop manager was very surprised that I hadn't heard any noise, as am I. Or perhaps this explains why my wife says I never remember the things she told me - maybe I just can't hear out of that ear. I appreciate the responses I received, especially Marco's telling me to just take it to the shop. To add to the data, the car is a '97 M3 with 39,700 miles and has seen about 10 track days.
