IMS Flange replaced but not the bearing?

If they removed the outer seal on the original (1 or 2 row???) bearing, that would be good.Any mention of that ? From the part # of the replacement flange on the Invoice , you may learn which bearing you have ?From your MY of 2003 it is probably a single. Others may have better suggestions.

Here is the section of the invoice that shows the parts used. There is a part number for a "SEAL RING 27 x 3" but I'm not sure if that means anything. Why would it be good if they removed the outer seal? Thanks again for your input.

Many believe that if you don't change the bearing then removing the seal on the existing one improves longevity.

Porsche dealers will install and even recommend...they just won't provide any warranty. In fact most dealers will install anything you ask them to. My dealer recommended the IMSB be replaced and provided me a quote to do so but I opted for the Solution installed by a certified shop.

,,,because the grease in the original bearing leaks out when(not if) the seals fail. So it makes sense to provide an oil bath for the bearing by removing the outer seal.This is exactly what most new IMSB kits do and have done for years. It is not so much belief as proven field results from thousands of IMSB retrofitted cars.Obviously an upgraded ,new IMS bearing is a way more intelligent alternative but in this case, the OP got neither it seems.YEMV

I believe that removing the seal is a good thing. However, others may not so I am covering my bases

So I'm new to the community, have been researching here, and now close to pulling the trigger on an '02 C2. 
I've pulled the maintenance records from the dealer, where even tires were replaced/serviced by the owner. While I had the service advisor on the phone, I asked more pointed questions of the data dump that he sent me.
The RMS was replaced in '06-- what is the typical service life of these? The PPI will of course reveal its integrity now, but I wanted to see if there was a rule of thumb (other than if it ain't broke don't fix it).
So here's the peculiar part: in the same RMS service above, the dealer replaced the IMS Flange (according to the service notes), but not the IMS bearing itself. Does that strike you all as a bit odd? Or was the IMS bearing issue not yet known and infamous in '06? Was the design of the flange in the '02 MY flawed somehow? Why would the dealer skip the bearing-- the labor is done and the part inexpensive. I can only assume the bearing was pulled and determined to be sound enough to reinstall the existing one.
Thanks for your advice, and I hope to be a 996 owner soon.

Understood. Fortunately the aforementioned scatological skeptics are absent from this Thread -so far :-)

I will be stopping at my local Porsche dealership tomorrow to get an oil filter. I will ask the service department if they will install an LN Engineering bearing or the IMS Solution, which requires notching the case for the oil line.

Which means they will only install a Porsche part. In this case, the larger 997.1 single row bearing that requires the case to be split.

These cars are too old to go to the dealer, anyway.

I went to the Porsche dealer in Greenville SC today to pickup an oil filter ($32!), so I can do a rush oil change this weekend. I spoke to one of the service managers while I was there. He stated that they would be willing to install an aftermarket bearing that he sourced, since there was no Porsche alternative. To him, cracking the case to install the larger M97 single row bearing was not a realistic alternative. I asked about the IMS Solution and some of the other bearings that require the engine case to be notched to install an oil line and he said absolutely not. They would not make any modifications to the case.
