I am glad that your 4.7 is back together and hope that you get several more years of value from it.

Reading this and other posts about the 4.7 has left me wondering if scheduled oil testing like that offered by Blackstone could predict 4.7 problems before they happen?

Caterpillar's oil analysis program seems to be able to red flag future problems in some of their engines.

The 4.7 seems to be an engine where more frequent oil changes may be economically beneficial.
