This thread is nearly 5 years old, but I'll try and help. Most of the time, it's the lower bolt that strips out. Mostly due to small shavings accumulating in that area. Usually you can replace the bolt as the threads on the bolt are the ones that go bad most of the time, not the cases. But if the threads in the cases go bad, yes you can remove them without pulling the complete engine.
