The bearings indeed can be a failpoint. A guy on starquestclub has over 300k miles on his motor with original balance shaft bearings. His motor is meticulously maintained.

My motor has maybe 100k, and the bearing looked like crap. Case by case, check and assess what you have. Then make a call, but based on the motor your describing, I doubt the bearings will be ok as is.

I haven't ever heard of needing to replace oil pumps. From what I read, most of the time, it's still perfectly in spec.

I too should read Eddys article.
