Using Rare Earth Magnets

[Grumpy]

Using rare earth magnets on/in your oil pan, drain plug, etc.. Do you do it?

Or at least when breaking in a motor? You can get them for free if you have any old computer hard drives laying around. I split and opened up a total of 14 older apple hard drives that I had down in the basement, took me about 5 minutes each. The magnets range from 2.5 inches to 1.5 inches in length, by about .75-1 inch wide, and are shaped like half-bent horseshoes. Little fuckers are powerful as shit. Get 2 of them stuck together and you can play hell trying to pry them apart, especially without tools.

I put them inside the bottom of trans pans, inside oil pans, on the bottom outside of oil pans, etc.., on drain plugs, wired and glued to dipsticks of small 4 stroke motors when breaking in, etc. They grab a lot of ferrous material, especially on break in. You can also buy them fairly cheap from China on ebay, etc.

Ive generally used hardware stainless screen epoxied over oil drain holes, and ceramic magnets to limit broken valve train debris reaching the lower crank case

be aware that all magnets are damaged to some extent by heat,
but some are far less likely to be damaged than others
oil temps can raise the magnet temp of a hard drive magnet,
in some cases oil temps get too high,
high enough heat or permanently damage the hard drive magnets

there are better magnets for that application

magnets are ceramic and glass hard, don,t try to drill or grind them, as they can shatter


proper magnets trap metallic debris

the magnets RICK linked too have a max operation temp of 302F
which is higher than your oil temp should ever get even close too.

but Ill point out I switched years ago to these ceramic magnets, in oil and transmission sumps, as I feel they are superior
(just remember to use epoxy to affix them to non-ferrous surfaces as they can not be drilled or bolted)

I actually add one to the outside bottom of my oil filter and it is impressively strong.
Every time I change a filter on the Camaro I cut it open, inspect it and transfer the magnet to the next filter.
It typically only gets a real lite dust like ring inside around where it was installed.

I also added one that I found on here to the bottom of my oil filter this weekend:

176F max operating temp, but they're stuck to the bottom of the oil filter and should get plenty of airflow over them, so I think they'll be ok.

I used the same temp rating, but didn't want to cough up $36 per magnet so I went with a RX864 that cost $11.88 and bought two. Your RZ0X84 has considerably more pull thou at 57 lbs.

$11.88 sounds way better than $36.
