So if I fit the retrofit, do you also suggest I plug the ims shaft or will it be ok with an open shaft? Will the engine be starved of oil when the shaft fills with oil?

Unless you are using the IMS Solution, then no plug is required with any other LN Engineering product. Why? Because the bearing has an inner seal that does a great job of keeping ANYTHING out of the IMS tube. Oil, air, gases (insert laughter here) or even smoke, after the engine explodes!

I have extracted many classic single, dual and Single Row Pro LN IMSR bearings and to date oil has NEVER been found inside the tube of an engine fitted with these. Not once, not ever, and that takes into consideration the removal of the very first IMSR bearing at least two dozen times to check it during development.

The IMS Solution is a different story, as it's journal bearing delivered oil into the shaft, and fills it within seconds after start up of the engine, if the plug is not in place.

In short, follow the directives of the manufacturer of what you are using. Don't try to out smart them, as its the quickest way to shoot yourself in the foot. of course, that only pertains to truly developed products, not those that are cobbled together in someone's garage.

Oh, so if I'm understanding correctly the bearing is only open from the flange side,and it has a seal on the shaft side. So that also eliminates the acidic oil that gets accumulated in the shaft with the original bearing,right?

Last I looked Air is a gas, comprised of 78% N2, 21% 02 and various other gasses.

The gases in Earth's atmosphere include:
Nitrogen – 78 percent.
Oxygen – 21 percent.
Argon – 0.93 percent.
Carbon dioxide – 0.038 percent.

I know I might sound stupid and that this has been discussed many times, but what about the ims retrofit bearing together with the oil fed flange from the ims solution? I know you obviously thought about this,but why is it better to run the retrofit on splash oil, would more oil do it more harm than good?

The LN bearing is designed to work without an oil feed system, and the flange from the IMS Solution will not fit with any ball bearing unit, it is designed to only be used with the Solution solid bearing.

Oh ok. But my question is, what will happen if you add something similar to the retrofit bearing, will more oil end up doing any harm to it? I'm asking because I was always under the impression that any rotating part works better when it has oil being fed to it. Are ceramic bearing that much different to steel bearings in that just splash oil will do?
What would be the results if you had to compare a normal retrofit installation compared to one that is fed oil, which one would last longest? Most probably Jake has gone through this already,just curious to know what the results will be.

I have only one comment here...
Don't overthink this.
The LN dual row bearing was designed to work in its intended environment.
Added "improvements" are unnecessary.
You can heed the advice of JFP and Jake Raby, they know what they are doing...
So maybe that was more than one comment, but I was on a roll.
