Excellent - been following this with interest (and hope).
The seal at the bottom where the oil pickup is starts to harden and then lets the oil drain back into the sump causing oil starvation and in the end, a goosed engine.
The seal goes hard, air is then sucked in which then causes oil starvation.
The first noticeable thing you’ll see is an “Oil Pressure Low – Stop Engine” error message every morning or when the car has been sat.
The comment you found about not using the Polish part as it reduces the diameter doesn't give any evidence that it actually causes a problem. It sounds to me like it's been made by someone who doesn't understand fluid flow.
