Oil filter Magnet
Are the oil filter magnets along the same lines as those tornado intakes or do they actually provide some benifit?
Also how well they they stay stuck to the oil filter?

I've heard they provide some benifit in trapping smaller particles from circulating, especially durring initial start up after a rebuild.
Thanks

I don't think they would be that great. The magnet would not have enough strength to pull small particals thru the oil to the side of the filter. With oil flowing it would be even harder. Magnets do not work well unless the parts are touching or very, very close. And the mass of the metal makes a big difference as well, more being better. I think the magnetic drain plug is better because its in contact with the oil and it does it's work when the oil settles to the bottom.
If they are real cheap, it will not harm anything, so if it gives you some peace of mind then use it.

I've seen an oil filter cut open with the magnet still attached, and you could actually see metal dust on the inside casing where the metal was. I can't say whether that means they are more effective than an oil pan magnet.

The TH700R4 I helped a buddy install last weekend had a magnet in the bottom of the pan, and it was absolutely buried under a wad of slime. Not much metal at all...as tested with another magnet...but it sure did a good job of holding some of the scum out of the trans.
I think it's just enough to be worth it. Oil does contact the magnets so you have the chance of pulling a small percentage of material out of the fluid. That's worth it in my book.

Here is a little tip. When your computer hard drive dies or is no longer needed, open it up and remove the "Rare Earth" magnets inside. These things are stronger than any other magnet you have seen before. Then stick them on the oil pan close to the drain plug, (and believe me they will not fall off) then at each oil change remove them just before draining the used oil and whatever was trapped will "Go with the flow" The best part of this is the cost = $0.00

Good idea. What do they look like? Are they small? What shape?
Some hard drives are VERY hard to open unless you have a security bit set.

Most of them are just TORX, like a T-7 or 6 when you get the case open you will see the read / write head that floats over the platter, The magnets are under the backside of the head. Really once you open it up it's pretty clear where they are, and if in doubt just poke the screwdriver around and they will "Grab" it.

Cool idea. I'll try that...I have lots of old junk hard drives laying around.

Thanks for the info.
I have the magnetic drain plug, but was wondering of a $40 oil filter magnetic was worth it. I was looking at the MID Americas versions and I'm not going to buy it.

The filter element would catch all those particles. Put the money into a good filter element and don't waste your money on a magnet. That's forty years of working in hydraulics talking.

Do a search on the net for NEODYMIUM MAGNETS. We use these types of magnets to hold wings onto model airplanes!! I have some from a CDrom motor stuck to my work bench. Once I was cutting a bolt in the vise and the shavings were attracted to the magnets about a foot away. They are some really strong magnets that would attract through and pan or oil filter.

this is an old trick and its one of those" better than nothing " things. it not gonna change the world, but it will help out your engine somewhat. just open any late model vehicle trans pan and they all have magnets on the inside of them. the muncie i pulled outa my vette, had mag drain plugs in it. so its nothing new. as for the high buck filter mags....... just find an old speaker and bust the mag out of it and put on the side of the oil pan. its what ive got on the toyota. its stronger and covers more area, and its free!

I think he's saying that fluid moving through the block and filter is essentially hydraulics on a more general scale. Same principal applies...and he's saying the metal in the oil will flow right by the magnet more often than it would stop and be caught by it.
