Just got my 2002 S out of the shop last week. I left the car on jack stands elevated in the rear for several weeks waiting on some brake springs. It may be coincidence but after installing the springs and driving a short distance the air oil separator failed with very loud sounds and what sounded like rotating metal on metal. It only lasted a short time and I was less than 1/2 mile from home. Service maintenance light came on. Replaced the AOS but it just did not seem to be running properly. Cam timing was about -2 and -5 but appeared to be steady. Took it to shop less than 2 mi home. The mechanic dropped the oil pan which was completely clean. I change oil faithfully, but one of the first oil changes had some very tiny metal flakes on the magnetic plug. (none since). The clutch needed replacement and having concern about the metallic grinding sound I had the mechanic go ahead and replace the RMS (minor leak that had been documented at the dealer over 2 yrs ago) and the IMS bearing. The bearing did not look too bad but it did have a very slight wobble. It am a firm believer in preventive maintenance. Clutch, RMS, and IMS bearing replaced (LN). Runs much smoother and quieter.
