Magnets in/on oil pan

[Magus2727]

Once I get my motor built I plan on doing the blackstone-labs on every oil change so I have a good history of the motor since the rebuild. The magnates would help just keep the bits between the oil changes...

Even with that much attraction you'd be surprised, there are too many forces on an external magnet. Water puddle hit at speed can easily move or remove one, it instantly moves a car weighing much more than 50 lbs. Putting mag inside perfect, you don't NEED to pull it and clean it, just leave it alone. Moving an external magnet will not carry all the particles with it, some will stay behind to then be loose, a mistake. The oil itself has enough resistance to pull some of the particles loose off magnet. The crankshaft could care less about any magnet in there..........

That could get expensive. I Usually do once every year to year and a half.

I bought magnetic drain plugs years ago on ebay for a few bucks, and they looked like what you proposed to build... a long earth magnet drilled in a drain plug.

I had them in my 5.0 and that engine has two plugs, when I did oil changes I had to make sure they were far enough apart so they wouldn't crash into each other. lol

I only drive approximately 3000-3500 miles a year so that would only be about once a year. Its mostly a commuter / track car. I also don't drive it in the winter, the low ground clearance with the additional lower front bumper makes me a snow plow when their is more than 4" of snow on the ground.

ATX pans have a round magnet in them. After 130k miles mine only had a fine metal sludge around it. You can magnetize the drain plug in the oil pan like you did without high tech industrial equipment. You just need another magnet and stroke the drain plug in the same direction.

As far as spelling - it's a personal thing for most people and at different levels of OCD. Most come here for an informal gathering to communicate solutions. I can look over some of my past posts and think - what the hell was that I was trying to spell. Or I knew how to spell that. Sometimes the brain gets ahead of the fingers and ideas.....

If you do choose to mount a magnet inside the oil pan (or anywhere internal), be aware that most neodymium magnets are plated, and that plating flakes off rather easily.
(I think they are nickel plated, it's shiny and not magnet attractable)

not sure about sumarian cobalt ones

I have personal experience with the ones I listed. They are very well plated and don't flake as long you don't bash them against anything and use care when putting them on and off. They have gold plated ones also which I think plates better.
