What is the name/manufacture of the sin bearing?

[epapp]

I agree its a plus that the IMSG means much more than just a bearing problem, i.e. alerting you of more than just IMSB failure.

But the failure rate of those other parts you mentioned seem to me to have a much lower probability of failure when compared to the IMSB. Sure cam chains can break, and the IMSG will probably pick up on the metal fragments and alert you, but my quest is to solve the issue of unknown IMSB health given my cam chains will probably be fine for the life of the engine (probably just jinxed myself).

I'm not the type that loses sleep over my IMSB failing, but it sure is time for some real engineering (probably set off some short fuses with that one).
