I guess what I don't understand is the following: if the inner seal on the IMS bearing fails, allowing engine oil to contaminate the grease and cause bearing failure, how will the inner seal be strong enough to hold up to lubrication from a separate line into the housing/cover? Furthermore, are the bearings designed for, or at least the same as ones designed for lubrication by crankcase oil? I'm sure there is a simple answer and that I am showing my ignorance, but I am having trouble wrapping my alleged brain around all of this!
