Taxi?, my independent tech is a 25 year Porsche wrench. He told me Thursday (before I'd done this oil change) that he's done about 25 or 30 of the LN retrofits. He knows that I'm familiar with their products (I've been following this IMS deal since I got the car) and that is definitely the route I will go. Thanks for the offer to tap you as a source. Hopefully I won't have to bother you. Does J&W have a website? I'm assuming you mean Doral as in Miami, right? Thanks again.

I had an '06 997 C2. M96 engine like yours. I bought the car new from the dealer. I changed the oil and filter myself at about 5000 to 7500 mile intervals (one of the easiest oil /filter changes of any car I've ever owned--been changing my own oil for 30 yrs.) Mobil 1 0w40. Car had 45,000 mi when I traded it in.
I cut and inspected the oil filter for the last few oil changes I did. It had many, many approximately 1x1mm to 2x2mm paper-thin flecks of metal in the pleats. They were definitely magnetic, as they were attracted to a shop magnet, and jumped an air gap to stick to the magnet. They were NOT chunks, like coffee grinds. They had tiny, fine, parallel score lines on the flakes.
I was following the IMS issue, as I was paranoid about a possible sudden, no warning catastrophic failure.
If I had kept the car, I DEFINITELY would have done the L&N Engineering IMS retrofit.
BTW, the Tiptronic retrofit is a good bit more involved than the 6speed manual retrofit.
Also BTW, I never did find out what the metal flakes were.

Thanks BlueJay73! This describes my "flake" finding exactly, although I only found a couple of them and, like you, no chunks. I'm planning on the LN retrofit.

Might want to check the cylinders for scoring as well.

It is typically the#6 cyl that begins to seize and show damage. Hence the borescoping rec. Personally I would not drive it until I knew what was going on.
