I agree with Bruce. IMHO Pedro's solution is the only one that follows what I naively consider to be actual common sense. Everything I ever read about the IMS failures was that the grease seal failed and let oil into the bearing, whereupon it just washed out the grease and got basically stagnant and eventually failed. And as I recall, it was on Jake Raby's or LN's website that I saw this. The LN solution is no doubt a better bearing, and no doubt splash lubrication is better than a grease seal failure, but OTOH the main problem was not the bearing itself, it was the lubrication. It seems to me to be good common sense that pumping oil onto the bearing has got to be better than just hoping it gets lubricated with splash (although if someone could say definitively that the IMS sits IN the crankcase oil, I might have to take that back). Dunno why that information is so darned hard to come by.

Regardless, Pedro's solution happens to be the only solution out there I've seen for those of us with later-model Boxsters/Caymans with the IMS that can't be replaced without engine teardown. My 08 is a very low mileage garage queen. I understand that the best thing is to drive the car as often and as far as I can, but ... I bought the car to be a garage queen. It's a weekend fun car for good weather. I do not live in Southern California (I wish) and I do not WANT to subject my beautiful car to all the dirt, rock, cinders, rain, ice,snow and assorted other crap on the road in my daily commute, around here, nor do I want some @$$hole to ding my car door in the parking garage. I want my garage queen, I just don't want it to blow up. up on me. My understanding is that the last-generation IMS bearing was actually quite robust although Porsche still never addressed the lubrication issue. and now we are starting to see failures in these cars as well This is scary, and this being the case, Pedro's solution seems to be the most likely way I can reduceaddress theis risk of IMS failure. . With lubrication, logically speaking my more-robust IMS should then be just about bulletproof. Yes, I understand that the risk with the OEM setup is already very slight, but taking my even that slight chances on arisk when the cost could be $20,000 repair versusK to fix seems dumb when I could spend $2000 K or less to make the risk pretty much go away seems like a good tradeoff..
