DIY Magnetic Oil Filtering

[rick3000]

I was recently looking into a magnetic drain plug, but decided against it. The reason being I read a significant amount about how some people are weary that the magnet attracts metal (assuming there is any) and the particles build up into a mound, and then break off all at once, causing a large number of particles to enter the engine all at once, instead of individually.

Do you guys think there is any truth to that though? I think that would only apply to the drain plug, but I am curious what people think. Any recommendations on better oil filters, than OEM, to trap more particles? Thanks!
