Right, got rid of the IMS, and at least in the 911s I have yet to read about the newer 9a1 motor having any bore scoring or cylinder chunking issues. Don't think the smaller boxster engines were as affected, and really it's internet-tastic for the most part but still affects resale and peace of mind.
I can think of at least 3 people that autox regularly on the older motors, 2 of them over 100k and none have had ims, scoring, d-chunking, etc issues.
