IMS bearing question

My IMS was full with engine oil, and I read the same in all of the reports of bearing replacement. In my understanding filling the shaft with oil can only occur from the flywheel side through the bearing, if the pump side is not punched through. So in all these cars the bearing lost its original lubricant long ago and was washed out with engine oil. My impression is that, as the IMS sits on the bottom of the engine, it`s close to the oil level in the sump so it can get excessive oil by splashing. This may be sufficient if you remove the seal and keep the oil level close to maximum. I`ll look more into this next weekend since now the engine cases are apart.

Maybe just buy the cheaper Porsche bearing and plan to make it a maintenance thing with clutch jobs? Is it worth more to put in a more expensive bearing? Who knows at the end of the day. If it were me, and I were rebuilding the engine anyway, I'd probably go all in and do the Solution and be done with it. Simply because you are there, and trying to justify cost vs value is pretty pointless as rebuilding the engine takes that discussion right off the table.

The cheaper bearing (pelican I assume) is to be replaced in every 40k miles, costs $180 and is worse than the original (being half in size). Why not just buy a new double row bearing same or similar to the original that looks perfect after 100k?

Misunderstood... Yes, if cost is an issue, replace with a factory bearing and plan for maintenance. Or, since you are there, consider the $$ for the one and done. The IMS “discussion” really has become the proverbial oil thread. There are several options and price points. I think it simply boils down to which you feel the most comfortable with across the board. Overall, in terms of replacing it or not, it’s a bearing, and bearings fail. Do it while you are there.
