I'm just sitting at the office waiting for a call and you got me curious. I'll do some Googling for you at no charge.

I am not aware that LN produces a roller bearing replacement for the IMS. There is one that they offer on their web site as an "economical alternative to the ceramic roller bearing". But it appears that it is actually createded by RND Engines rather than LN.
LNE states: "We did develop a version that utilized a cylindrical roller bearing with thrust ring, but it never made it from testing to production for the primary reason that Porsche chose a ball bearing originally, not a roller."

There is some interesting discussion of OTHER roller bearings here:

and here:
EPS Eternal fix Cylindrical roller bearing ims with oil feed - Rennlist Discussion Forums

By my read it looks like the biggest problem with the roller bearings is dealing with thrust force. It looks like that one, sold on the LN web site, handles the load well and does not require an oil feed. Oil feed implementations may vary in success, so I like that this one does not need it. It costs the same as the ceramic ball bearing replacements.

I have no experience with it, but it looks like a good 4 year/50,000 mile choice.

IMS Solution Retrofits

Just ship your car to Jake Raby at Flat 6 Innovations like I did and have him install the plain bearing, oil fed, IMS Solution. Lifetime fix.

Just do it and start enjoying life.

His car may not be a candidate for that without a complete engine disassembly. ...and any fix that feeds potentially contaminated oil into the bearing is also not a good idea.

.....well......based upon THAT...



He is so far past screwed, he can't catch a bus BACK to being screwed.


A new IMS is not going to help that time bomb, only delay the explosion.

Thanks for the head's up.

New engine time.

Yikes.

Sorry, Dude.

My IMS Solution feeds just filtered oil from my Spin On Filter adaptor directly to the IMS Solution flange. This is the cleanest oil in the engine, as it has just passed through a filter less than 1" from the oil feed outlet.

Do NOT confuse my patented (US Patent 8,992,089 B2) IMS Solution with some other "oil feed" product. It shares nothing in common with those.

Pre- Qualification procedures originated here. Thats why of the IMS Retrofits that we have carried out under this roof (over 600 to date) not a single one has failed. Assuming that an engine is healthy, or retrofitting the IMSB on an engine that is known to have debris laden oil, makes zero sense. If you compare what we actually do, to those who just install an IMSB, then you'll see where the value is. I maintain a 6 month backlog on IMS Retrofits, so we must be doing something right.

That said, the RS Roller Bearing is NOT an LN Engineering product. It is offered by RND Engines directly to SSF Auto Parts, exclusively.
