When I bought my 04 with 55k on it, it was taken in and had a new clutch installed soon after. Then I start reading about the IMS issues,as everyone else had said " scared the hell out of me" at first. I decided that I would get the LNE bearing done, but I put it off. Now I hear about failures to the new bearing and it makes me wonder whether to do it or not, or install the "guardian". While I do believe that this is a problem with these cars,and not a hoax, and that LNE's bearing is superior, I don't like the fact that it can be fouled by foreign debris in the engine such as the gasket material found in peoples oil filters or the chain tensioner paddle filings that seem to be in alot of filters opened up on this site. It seems that if a small piece of non-metal debris mentioned earlier got washed into the new unsealed bearing it could cause the balls to slide instead of roll which wouldn't take long to destroy it. Three of the failures of the LNE bearing are foreign debris failures. I'm beginning to wonder if there is a cure for this issue, or if you trade one risk for another. With all that said, I think I would install the bearing if my tranny were to be removed for a little piece of mind, but I try to not let this issue destroy my Boxster experience. Life happens-deal with it when it does.
