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.
