It seems like you're misinterpreting the suggestion of reaming. The suggestion was to use a reamer on the plastic molded part after it ejects from the mold, not on the injection mold itself. This would allow the manufacturer to hit tighter tolerances on the hole diameter than can be achieved through molding alone, and without any risk to the mold. This is called "rework" and is often avoided in the real world because it is time-consuming and potentially labor intensive at high volumes (higher cost). It's not desirable, but if a manufacturer is in a position where it is the only way good parts can be sent out the door it is sometimes a reasonable course of action. However, Andy stated it is not clear whether this tighter tolerance would even make much of a difference.

I would say "a reamer? oh that's easy enough to test on a few parts", but it sounds like AndyMark is unable to reproduce the problem on more recently molded parts (actually a good thing, but frustrating if you're troubleshooting the issue...). So it would be difficult to evaluate the effect of reaming without a failing baseline for comparison.
