Hello emdog. Years back you created a thread/posted a video on a high pitch "saw like" sound emanating from your 911 upon startup. It would subsequently stop shortly after the motor ran. I have the same problem with my 2001 911 C2. Did you ever determine the source of the problem? I am worried it may be the IMS bearing staring to fail. Your response would be greatly appreciated.
Thanks.
