Since we don’t have superconducting, helium cooled, maglev bearings, we are left with the same old roller or ball bearings with moving bits that can fail, or diamond like coated, high pressure synthetic oil floated, plain bearings. Seems simple to me.
EVERYTHING can fail. No kidding.
It was an exaggeration to make a point.
What kind of bearing is in all of your crank journals and piston big and small ends?
What kind of IMS bearing is in a Metzger engine?
Physics is physics. How anybody can look at all of the designs available and not choose the Solution is beyond me.
Alright, I will shut up about it and quit posting and go back to actually driving the snot outta my Boxster and see if I can grenade the damn thing and give you a failure data point to share.
Freaking paralysis by analysis.
Just install the “Solution” and get busy driving. We all only get so many sunsets.

Ok....
...I stand by my statement.
The "IMS Solution" will NOT grenade.
There. I said it.
How many of the plain bearings on the OTHER end of the IMS shafts have failed?
I had to stop to refuel, so I figured I reply.

I think Jake spent a long time and a
Lot of research in Determining the exact metals to use in the solution. If you have held it in your hands It
Definitely gives you a very good feeling that it will not fail.

The plain bearings on the other end of the shaft are not on the bulk of the load.
Like I said, it looks promising. But, since I'll never change my original dual row bearing anyway, it really doesn't apply to me.
My point was that an opinion is just an opinion.
Looking at it from an engineering standpoint, they will fail. It's just a matter of when and whether or not they will outlast the engine/car.
The added friction could also cause wear on the shaft which isn't built (hardened) for that type of bearing/friction.

And so goes another fine technical discussion of the IMS.
Cats anyone?

You are always a welcome source of humor.....
In response to your question, thanks, but no. I have a few of them already. One of which put a nice scratch on my plastic window...through a car cover no less. Perhaps it was from under the cover....who knows. If they can cause damage, they will. If my LN bearing fails, I'm sure that my cat was somehow behind it.

I was wondering for the people that go with the Retrofit how they handle the service intervals? I'm looking at a couple cars with the IMS Classic which has the 4yr/50k mile recommended service interval. Both cars are approaching the year time frame (doesn't bother me) and have about 30k miles on the bearing. Both cars have had their oil changed at least yearly and appear to be in good care.
I called LN Engineering today and they said the bearings should last longer than the interval but they like to see them changed. Many factors go into the life span of the bearing and that is the number they came up with.
The Classic has such a shorter service interval than the Classic Pro and Duel Row bearing, I guess I'm concerned and buy into the IMS fears. Just trying to wrap my head around the topic.

Particle wave....
...I'm just kidding about it NEVER failing. Of course, any part can fail. My point is that the a forced lubricated, plain bearing, with a diamond like coated surface, is the most reliable type of bearing for that application.
And over the last 100 years or so of internal combustion engines, that seems pretty well proven out in the real world.
There's no tone in text, so I probably came across a bit strident.
