This past Thanksgiving week my IMS bearing failed, resulting in a catastrophic engine failure. 2005 997S with 34,000 miles (garage queen, multiple PCA zone/region concours winner. Luckily, CPO still valid! Prime Porsche near Boston did the work. While driving it locally, I felt/heard two short rattles coming from the engine (death rattle?). The car drove fine the remaining 15 miles home. 15 minutes after parking in the driveway there was a 2-feet diameter oil pool under the car. After flat bedding it to the dealer, the tech drove it into the shop. He indicated that normally the engine will not run at this point. He found the oil filter full of metal shavings! PCNA approved the engine replacement on that basis.

What is your engine number? I'm betting you had an early 05... before the switch to the larger bearings.
Let us know!

Should I be concerned?
14k C2, early 05, po have RMS replaced. Last night I changed the oil (9 mo and less than 3k since last) I noticed on my L&N magnetic drain plus some grayish grease... Is this normal? It wouldn't indicate a leaking IMS would it?
I've been using Motul 5-40w since ~9k. Extended warranty through Costco.
Thanks for any thoughts or input in advance.

IMS stands for intermediate shaft - the shaft doesn't leak. It's a shaft.
IMSB stands for intermediate shaft bearing - they don't leak either - but they do fail catastrophically.
The IMS flange has been known to leak - but that's no big deal in and of itself.
Anyway - nothing you report is a concern.

I have one of the early build 05's (can't remember exactly, but August 04 build date I think?). I just had the RMS replaced due to a slow leak, so of course I did the L&N IMS bearing and clutch assy. The car has 56K miles. I looked at the old IMS bearing with the tech and it was completely intact, and rolled smooth as silk. The rubber seals were completely intact and unmarred. I feel good that I have the updated bearing now, but it's also nice to know that the old bearing was holding up well. BTW, the clutch disc probably had 25K miles left in it.
