There has not been a single documented IMS bearing failure either in this thread, any other thread on either rennlist or 6speed on a post mid 2005 997.1 after they went to the larger bearings.
Alex911 - Enjoy that Targa, they are awesome, I had a red '07 T4S. Put an IPD plenum on it!

Yes, but remember "on a post mid 2005 997.1 after they went to the larger bearings." it does occur on the 996 and the early 997 normally aspirated engines. Although extremely rare and preventative options are available, when IMS bearing does fail is catastrophic!

IMS failure
Two weeks ago while my car was in for an oil change, they approached me with the dissected oil filter. Metal particles in the filter. My shock is just now fading. The car is a 2005 997S with a build date of 03/2005. I had 33000 miles on it. Never tracked but driven spiritedly only on weekends. Magnetic drain plug, 1/2 dozen oil changes and new L&n hybrid bearing in place. What next?

Please post the results/findings. I thought I was safely out of the woods with the LN kit installed last year on my 05'. I really hope those of us with this kit installed do not have to be terrorized by another looming catastrophe. I just don't have the stomach for that. Was the metal magnetic?

It says he joined in 2011 not 2001, and why should he have to defend himself to you or anybody just because he hasn't posted anything until now. Maybe he just didn't have anything to say before.
And what does he possibly have to gain by calling PCNA. Even if his car is inside the class action suit, he replaced the OEM bearing with an LN, i.e. aftermarket mod, so not sure how that would affect eligibility.
And he described it as "metal particles". You changed it to "flakes". Big difference. Tiny particles could be coming from anywhere in the engine, not necessarily the IMSB, and might not necessarily be predictive of impending catastrophe. This is why in addition to having the LN bearing installed in my '05 I also got a full bumper-to-bumper exclusionary warranty on it.
To tsearle00: is this shop a Porsche specialist with water-cooled engine-building creds, and were they the ones who installed the LN bearing? How well do you trust them? That's what I would want to know before attempting to answer your question of "what next?".
PS: So far I have 25K miles on one of the original single-row LN retrofit bearings with no issues. To be fair and honest, the car went 32K miles on the OEM factory bearing and it came out pristine.

Additionally, he posted it and then nothing for four days. If you posted a reply that you were concerned that your car might blow up, wouldn't you be more active if people were trying to help you understand your situation?
First thing, don't start the engine
call L&N and PCNA to get their thoughts.

Assuming the reason tsearle00 posted in this thread was out of concern that the metal "particles" could be an indication of IMSB problems, my advice remains don't start the car and get advice from L&N and PCNA. I don't know the size of the particles.
Given how rare IMSB failures are and that the L&N bearing appears to be a good solution, going with your gut on how much you "trust" your mechanic, who probably has not seen an IMSB failure does not seem like good advice. In fact it is just reckless, silly advice.
By the way, what does "Just saying..." mean in adult talk?

It's kind of all jambed together and a bit hard to decipher, but that's my take on it. Maybe he can clear that up for us.
