allelectronics.com I bought some nice 4" or so dia. donut neo magnets for pretty cheap. Have to be careful with them, they have a tendancy to suck tools on to them, etc. If two get stuck together it's a job to separate them. They fit nearly perfectly on the end of common oil filters.
 
Anybody want to suggest their source for good "Stick-On" magnets to use on the outside of filters? I remember seeing somebody mentioned something about some really strong ones awhile back, but can't find it now.
 
Google neodymium magnet.
Plenty of online and fleabay choices.

A good source is 'free' magnets froms crashed computer harddrives, small electric toy motors, and blown speakers.

Radioshack has cheap magnets. Not the strongest but cheap and plentiful.
 
Thanks guys, those big donut ones look like just the ticket. I got three of them put on the conventional outboard trans filters. Already using magnefines on one trans and four power steering units.
 
I like a magnetic drain plug instead of a filter magnet. First of all, you are able to moniter any wear metals on the drain plug. Second of all, it intercepts the metal before if passes through the oil pump.
 
Sorry, but I gotta call B$ on that logic. I run synthetics and long OCIs, so monitoring from the standpoint of pulling the drain plug is a moot point. Wouldn't happen often enough to do any good.

And I doubt those plugs are strong enough to do much good, nor are they exposed to enough of the flow to trap much even if they were. With a good strong one on the filter though, it is going to trap anything ferrous that might be in there as well as have plenty of opportunity to do so as the the oil gets pumped though complete cycles past that one area (filter).
 
Putting a magnet on the dome of a filter won't trap as much as magnets placed around the circumference. Not much oil flow on the dome end, unless the bypass is open.
 
No and yes, they will catch plenty if they are strong enough. The idea is to get enough field strength close to a regular flow. Those ones Porcupine showed me are the "really" strong ones. Dangerously strong. I daresay you might stick one in the wrong place and induce unwanted resonance in the rotating assembly. But you want it on the filter where the stuff it catches is easily disposed of right along with the filter.
 
You could get a couple arch segments for the sides and a disk for the dome end and have all the sides covered. I just used 4 arch segments that came out of a brushless DC motor I decided not to fix.

Those hourglass shaped oil filters sure are neat looking

i dont know if a flat piece of sheet steel would substitute a round steel filter housing, none the less i did try it with the hood of my car and was not able to make a paperclip stick to the underside when i placed a neodium magnet on the outside.
 
I use the KlearForce magnets on two cars since new. The magnets sit on the dome and after cutting open filters did notice a tiny amount captured during the initial break-in period at my first 1000 mile oil change

, nothing significant.

Much debate over value, but anything that improves removing debris is a plus in my mind.

The KlearForce magnets are VERY strong and think that I will use them from now on.

What it tells you about how fast your engine is shedding ferrous material is probably of more use than taking that small amount of material out of circulation.
 
Yep as well as a periodic Oil sample to pickup the trace of non ferrous metals / materials...

After 32K and 22K miles on vehicles, no evidence of engine shedding large amounts of metals etc...
