That sounds like salemanship, if they were that bad and failed that much they would be out of business. They have 50 motors with failed LN bearings? I don't even think there have been 50 failures worldwide, let alone just 50 at this vendor.

I would be interested to see the article.

If you really want to resolve it once and for all, LN IMS Solution. That said, I am on just the regular dual row LN ceramic retrofit for the last 40,000 miles/5 years and it has been working out.

I though RND engines came with their own version of the roller bearing anyway and not the LN ceramic retrofit? So if the EPS guy says cylindrical roller bearings are the best, you might have one already

Roller Bearing IMS Retrofit Kit – RND Engines

There is no way that 50 of these have failed in the last few years since RND came out.

I've been pretty impressed with LN products, but not so much that I've bought any. I simply put a high quality high temp single row back in to replace the failed one from my engine. Replaced the intermediate shaft with my modified version while I was in there. I do prefer the ball bearing over the roller as its design seems more tolerant of contamination, point versus line contact. That's purely speculation however.

I put a dual row direct oil feed ims bearing in from Tunersmall.com in my 2000 S. Seemed to be a good product. No problems so far-installed last January. It is pretty much the same as the dof product from LN (not the "Solution"), just uses a different oil source.
I am currently putting in a LN Solution in my 2002 base. Paid about $500 more than the Tunersmall.com product although it comes with a spin on oil filter adapter which the Tunersmall.com product doesn't include. The "Solution" seems to be a stupidly simple idea. Makes me wonder why Porsche didn't choose that route. Interestingly, the LN warranty materials suggest that there is no coverage for a DIY installation.
