I drained the oil into a clean plastic tub. Then I filtered it with a cone shaped disposable paint filter. Zero debris or anything. So it is good to know no other hidden engine wear/damage.

I don't see any pump to drive hex problems. The depth of the hex hole in the oil pump is much deeper than the bronze gear oil pump drive shaft reaches. Hole depth 1.04", and the calculated insertion is only 0.863"

I will double check my measurements.
