Thanks for the advice all, pretty much cemented my thoughts. Bearing is still installed but will be coming out now. Screw on filter adapter was already for sure, and now LN ceramic dual row is too. Joel1 point

Hi, Leo. Welcome to the forum. I was in San Diego in late 60's and early 70's. I remember it all too well. So, your question is really a classic "no brainer." Jeff is absolutely right. Please do not reuse your old bearing. Mine is actually sitting proudly on a bench out in the garage, along with an internal oil pump, and 2 timing chain tensioners from my 911sc. These are all very pretty and interesting to look at. Seriously, strongly consider going with an LNE retrofit bearing or putting in the LNE Solution. I will be facing this question in about 10k miles. Not to replace, but to replace with which of the two. I'll probably go with the Solution. This is all somewhat problematic, because there is simply no known way to predict when or if an IMS will fail. This issue resulted in a successful class-action lawsuit against Porsche, and lots of money got paid to people who purchased a 996 only to have the engine blow-up. Literally. Others, like myself, never had a problem, but for peace of mind changed over to the LNE retrofit "just because." I still feel it was money well spent, and still enjoy winding it up every now and then. For your own peace of mind, and because you have the ability to do the work yourself, and because you already have the engine apart, you should put in the update. Lots of info on the forum about this issue. Good luck. Cheers,1 point

Welcome to RennTech If you have already extracted the IMS bearing from the shaft, you cannot reuse it. The process of extraction damages most of the internal components of the bearings, which will lead to quick failure. If you have not extracted the bearing from the shaft, even though the unit feels relatively smooth means absolutely nothing. I would be willing to bet that there is already no grease inside the bearing, and the seals are hard as well. It would be false economy to not replace it.1 point
