The above site outlines yet another 'solution' to the problem of IMS bearing failure and seems to me to be the best yet. I have not contacted them with respect to price, but it has numerous advantages:
1. It can be used on any M96/M97 engine, even those with the larger bearing that cannot be removed without engine disassembly.
2. Rather than relying upon splash oil (as with the LN bearing alone), it provides for pressurized oil to the bearing.
3. I gather that unlike the LN Solution, this pressuized oil is taken from the cylinder head, rather than the oil pressure sensor, and hence it is filtered oil. If you have debris (plastic or metallic) in the pan, would you want that to be able to get at your unsealed IMS bearing?
There is discussion of it on Pedrosboard and I gather Pedrosgarage will be selling it shortly. Here is the thread:
