I guess also post any other info i may have left out... personally 1999 boxster 2.5 Tip 105k its had 0W-40 in it forever, plan on changing that next oil change.

The failure rate is anywhere from 1% to 8% according to the class action lawsuit against Porsche, which presumably was based on actual evidence from Porsche. And, if it's a good car, it darned well ought to have the original IMS (name any other make whose owners have to go into the heart of the engine and make changes as a preventive measure). Okay granted that some people are nervous nellies who make needless changes, but regardless, with the question you are asking, presumably you'll only get responses from people who have the original IMS and therefore your response rate ought to be 100%. I just don't get what that proves. At best it would be anecdotal evidence. Just going for a warm fuzzy feeling?

just testing the waters to see how many replace their bearings, i dont feel that i would care to replace mine unless i saw the shavings in my oil... thanks for the replys.
