I'm a believer in magnets too. I use neodymium high heat magnets everywhere. i use epoxy to glue them to my aluminium trans pan. I stick a couple on the bottom of the oil filter. I have some in the oil pan and in the cylinder heads. You would be amazed at the coating of metallic fuzz that is accumulated. When I adjust valves I clean the magnets and they always have a coating and when I cut the oil filter you can see the rings of the magnet on the bottom of the can where it picked up metallic particles.
