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

Dwight, where did you get the heat shrink?

That was the most difficult to find, lots of folks have 4 inch heat shrink.....but they want you to buy a roll at several hundred dollars..............but ;

Looks good. I have 2 done so far with the hose clamp. Heatshrink tubing looks like a great idea.
To initially apply the magnets, I used JB KwikWeld. I did them one after the other doing opposing sides of the housing. Even so, they started to slump towards each other a little until I put on zip-tie and the tape. The JB Weld alone may hold, but I am going to do the heatshrink.

I don't believe the oil filter housing will get anywhere near that temp
The oil in the engine, sure, but not the outside of the filter housing

FYI: The Samarium Cobalt magnets are better for high temp locations.

Since Oil temps can reach about 240C the Neodium Magnets may be ok
on the outside of the filter as they tolerate up to 175 C, anything inside will need the SmCo which can stand 250 C temps without losing magnetism.

I used the SmCo magnets on the outside of the filter and they are proven to work, and I'll never have to replace them. I think the set of 7 were about $30, but I can't find the source where I got them from at the moment.

I doubt very much the oil reaches 240 deg C - I wouldn't want my oil more that 120 max....

JayG - you must have asbestos palms !!

Ooops, correction those engine oil temps are 240 F not C, however the magnet temps are in deg C so 175 C = 347 F so the Neodium Magnets are also well within their range and will do just fine.

Thanks for catching that guys.

SO now once these super magnets magnetize or polarize the minute metal particles we have to figure out a way to turn them into Nanites and program them to constantly sacrifice themselves to constantly rebuild the IMS and other bearing surfaces and then our Boxsters will last forever....of course if we had that tecnology we could sell it and buy Porsche LLC

[Timco]

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?

[jb92563]

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

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

[thstone]

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

I like it.

[PaulDash]

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