PCV rerouting
I have rerouted my PCV hose from the rear of the intake to the vacuum tree on top of the intake. Should it be exactly like what is in this link or will it be ok where I have it?

I don't see why it would have to be exactly like what is pictured in that link. On my truck I swapped the brake booster and PCV valve vacuum hoses and all is well. I assume you did something similar?

There was an unused port on the vacuum tree on the top middle of intake. I got a longer hose & attached it to the tree.

Failure of the rear piston, rod, or rod bearing (cylinders 5 & 8). After
discussing the situation with several installers, the problem has been narrowed
down to the PCV system. This picks up crankcase gasses from above the #8
cylinder and dumps into the back of the intake.

The oil vapors change the combustion mixture in the #8 cylinder, which can cause knock (pre-ignition). This leads to holes in the piston, broken rings, failed rod bearings, and burned valves. When the PCV vapors are evenly distributed across all 8 cylinders, the problem is eliminated.
