My take on the Magnetic Oil Filter Housing

[Pdwight]

First I want to thank Tommy for donating me a housing to tinker with for this project. I used High Temperature magnets. Gluing them on was a tough and not without risk job in itself For one thing the little devils are slicker than snot on wax paper, the Cyanoacrylate did not have a good surface to hold onto. Next problem was after drying over night (I did one per night) the attraction was so strong the newly wet magnet would pull the previous one off and slam together splashing super glue everywhere. So I had to resort to using an accelerator or ester to make them stay in place. The next big job was finding triple wall heat shrink big enough to go around this and be tough enough to stand the rather hostile environment. I do not know how well it will hold up, time will tell the true story. I plan on doing my first oil change with Royal Purple this weekend and we will see.

If that is standard electrical heatshrink, I doubt if it will be robust enough to withstand the +/- 100 deg C oil temperature for very long. You will find it may go brittle & fatigue with extended high temps - at least it does on electrical joints that suffer a high resistance fault.
Personally I would have used S/S hose clamps to secure the magnets.

Thanks Steve, I think the duty rating on this is 170C in temp. Is the thickness of a truck tire inner tube...or perhaps a bit thicker....time will tell

That thing will almost pull a head bolt down to the sump with those magnets. Did you touch a wrench to the inside? Very strong inside? Better use those magnet proof wallets for your CCs.

I'm not in the know of how oil flows in the housing, but I was wondering if one or maybe two magnets would do the trick?

That heat shrink is a neat idea, be interesting to see how it holds up over time.

I was surprised and pleased to see how my Mag filter captured some very fine metal particles that was the consistency of sludge and easily wiped out of the filter housing with a rag during my oil change.

Getting these fine abrasive particles out of the oil should do good things to the longevity of the engine and especially the bearings.

Like you I could only use seven magnets as the pull is so strong it would be near impossible to position them before securing them down.

I simply used a stainless steel pipe clamp around the housing and semi tightened it and pushed each magnet into place under the clamp before doing the final tightening. Worked like a charm.



Magnetic Sludge visible at each magnet position. The particles are so fine they pass through the filter element.

I have my magnets! Ready for my next oil change!

Dwight, aren't you afraid of changing the Earth's gravity?

[jb92563]

Actually he IS changing the speed of time with those magnets.

Time will run faster with those magnets and unfortunately make your track times worse, but will make you early for appointments

[thstone]

Forget that mini-magnet that LN sticks on the end of an oil drain plug; you guys are damn serious!

I like it.

Could one simply stick a magnet (would have to be the right shape and size) inside the filter housing?

Mine is inside the canister.



I know that's not exactly what you meant. Not sure how that would work with the stock setup. If the magnet were small enough or broken, it might be possible for it to be sucked up through the bypass, but I don't know enough about the stock set up to say for sure.

Where do you get the magnets from?
I think this is a great idea.

Hi temp one so they will not loose their strength at operating temperatures ....or so they claim

[particlewave]

Thanks for the link, Dwight

I just ordered a 3/4" x 1/4" high temp disc magnet to put on top of my existing magnet in the canister. The one that's in there now is kind of small and weak. It looks like it will fit in there nicely and with 18lbs of pull will be much stronger than what I have now.

Just as an aside, 1 of those large bar magnets would be sufficient. 2 would be overkill. 7?

[Pdwight]

Now this would be overkill

That is nuts

[tomonomics]

Isn't the point of the oil filter to 'filter' bits of metal (and any other foreign object of a certain size)?
Or are you trying to attract pieces of metal that are smaller than (x)micron that the filter won't contain, as someone mentioned above.

Just confused as to why this is needed inside the filter, as opposed to a better filter that would contain these sized particles in the first place.

[particlewave]

Pore diameter in the filter media is restricted by the need for fluid flow. In other words, there are many ferrous metal particles that are small enough to fit through the pores of the filter media and if those pores are made smaller, the oil will not flow freely enough and/or the filter will become clogged by debris prematurely and cause either complete filter bypass or oil starvation.

Magnets in oil filtration systems are actually pretty common, just not on passenger cars.

I think this is a great idea guys, can't wait to try it, just have to be careful not to park over a manhole or drain cover.
