Ive used these for years, the object of using high strength magnets in any engine is to trap metallic debris and broken valve train component parts bits of worn cam lobes ETC. before they circulate with the oil and cause excessive wear and get embedded in bearings or bust the oil pump gears.
the combination of MAGNETS and a few shrapnel screens to limit debris reaching the oil pump from the lifter gallery can be very helpful in limiting damage to bearings and the oil pump.

these are NOT REFRIGERATOR MAGNETS "#0001" can pick up a SBC cylinder head, and you wont believe the amount of crud they remove from your oil and prevent from reaching the bearings

OIL FILTER MAGNETS THAT SURROUND THE OIL FILTER, WON,T HURT BUT REMEMBER THEY CAN ONLY TRAP DEBRIS AFTER THE OILS BEEN THRU THE OIL PUMP GEARS,
THUS OIL PAN AND LIFTER GALLERY MAGNETS, OIL PUMP PRE SCREENS DO MORE TO PREVENT DEBRIS FROM ENTERING THE OIL PUMP

http://www.summitracing.com/parts/FTM-RA365/

THIS is a good example of what happens to bearings if the oil passages are allowed to push small metallic debris, from wear like rockers,valve tips,cam and lifter wear thru the engine, use of a few small magnets, and shrapnel screens helps reduce or eliminate this

BE AWARE magnets heat tolerance differs so ask for and pay attention to the heat limitations, a MINIMUM of 300F for any magnet expected to be used bathed in hot engine oil would be smart

heres whats left of a failed roller lifter roller wheel, Ive seen several similar failures , roller lifter life and valve train component expectancy tends to be rather short once spring pressures exceed about 500 psi and lifter exceed about .700 with that failing the cam lobe was nearly instantly destroyed, without several magnets and a shrapnel screen trapping most of the debris damage would be even worse to the bearings that what it was as easily 90% plus of the crap was trapped by magnets and never entered the oil pump, if only a single one of those hardened roller bearings gets sucked into an oil pump the norma/ result is a seized or busted oil pump and almost instant loss of oil pressure

Ive been installing 4 of these lately in the corners of the oil pan sump,nothing magnetic (metallic dust from engine wear, assorted trash,etc.)can get past them, I also sometimes install one near the rear oil drain in each head to collect broken valve train shrapnel in case of a failure to limit damage on race engines. btw if you don't want to install them inside the sump you can J&B weld them to the outside of the oil pan permanently or just place them there if you want them removable,TRUST ME THEY WON,T FALL OFF ON THEIR OWN attached to the steel oil pan sump

ADDED TO THE BOTTOM OF THAT OIL FILTER, to help trap metallic trash, in that filter,
YOU SHOULD NOT NEED ANYTHING ELSE.
now I generally swap in a quart of marvel mystery oil for one quart of the total volume in the oil pan,
but its not required

failure to maintain a correctly functioning lubrication system,maintain, valve train control, provide consistent cooling and an ignition advance curve and to stay out of detonation can result in expensive lessons in engine repair

OilyMagnets2b.jpg


if you use a magnetic drain plug, this is fairly normal trash after several thousand miles running time

if you use a magnetic drain plug, this is a fairly good indication of major problems with the engine after several thousand miles running time



keep in mind ALL THAT CRAP PASSED THRU AND PUT WEAR ON THE OIL PUMP FIRST! placing the MUCH STRONGER MAGNETS IN THE SUMP HELPS TOO OR PREVENTS THAT
"so do you just stick it in the inside corners of the pan and it stays put?"
yes you can do it that way on STEEL OIL PANS, and trust me, youll see why they don,t come lose real quickly

"or do you attach it some other way as well? "

personally I place them in the corners and cover them with a thin coat of J&B weld to make wiping off the accumulated metallic dust easier when I pull the oil pan, but many guys J&B weld them on the outside of the pans sump,the only way your going to get the metallic dust out is to pull and clean the pan once in a while, because once the crud's stuck to the magnets its there almost permanently, but it won,t come lose and get back into the oil flow

"If you install it on the outside of the pan how do you get the stuff out? maybe just slide the magnet to the drain hole so it comes out? "

you could do that more than likely if you only used one magnet but with several I think the steel oil pan itself might remain somewhat magnetic even after the magnets themselves were removed, as long as its not being carried thru the engine by the oil they are doing their job

btw, add a few magnets to the oil pan and drain back area in your engine, the trap and hold metallic dust that comes from wear and increase engine life span by preventing that crap embedding in the bearings

http://www.kjmagnetics.com/proddetail.asp?prod=D66SH


these are even more tolerant of temp swings and retain strength at even higher engine oil temps plus they are smaller and easier to use

The SH material in the D66SH magnets, means that the magnets can be heated to 300° F without any loss of magnetic strength, unlike standard neodymium magnets that begin to lose strength at 175° F. Suitable for many high temperature applications.


the problem with that magnet on the oil filter,that most guys have seen and many guys use, like this....

is that anything that makes it into the oil filter has already traveled thru the oil pump gears,if for example a valve keeper or roller bearings fro your rockers get into those gears they can and frequently do cause massive internal oil pump damage or a busted pump and theres also some minute chance of it bye-passing the filter, yes its a big improvement over no magnets but its not a complete potential barrier to metallic crud in the oil passages
sum-900510.jpg

BUYING A TOOL and DOING SOME PERSONAL LOOKING AT THE INTERNAL PARTS HELPS
filter2.jpg

you might be amazed at what youll see with a tool that allows a close visual inspection of a filters internal components rather than makes un-informed random guesses.
actually knowing what your dealing with is helpful,reading some links and doing research is also much more likely to produce informed answers than engaging in a (IS TOO! VS IS NOT! ) style discussion with someone else whos equally un-informed

its basically a heavy duty can opener , or an oil filter cutter , is designed to make it easy to internally inspect oil filters, by allowing you to remove the filter element , from inside the surrounding (CAN) for close visual inspection.

if your concerned about magnets tending to trap metallic trash in the oil passages ,just place magnets near the rear head drain holes in the heads and in the corners of the oil pan sump, but after doing the magnet deal for years and refreshing blocks after using them and rodding out oil passages after years of use, I,M not a bit concerned with placing one in the lifter gallery front and rear areas, as they trap shrapnel, like bits of valve keepers, and needle bearings from roller rockers, if the valve train self destructs and have never posed a problem, you will be amazed at the accumulated metallic crud these magnets trap and prevent from getting back into the oil circulating thru your engine

if you really want to keep tabs on engine condition, regular oil changes, having a magnet like this on the base of your oil filter and the smaller magnets to trap loose metallic debris in the engine before it can run thru the oil pump and bearings and using a cutting tool designed to allow inspection of your oil filters after every oil change will provide you with a great deal of information and potentially prevent or at least alert you to potential minor problems, long before they become expensive major problems

shrapnel screens in the lifter gallery and magnets in the lifter gallery , rear drain holes in the heads and oil pan sump, plus a decent screen on the oil pump pickup go a LONG WAY toward preventing metallic trash from reaching the oil pump

these work great, for inspecting what reaches the filter,but if you,
place several of these magnets (LINK BELOW) in your oil pan,and lifter gallery, it reduces significantly the metallic crud going thru the oil pump, thus reducing wear and preventing some issues like busted bits of valve train reaching the pumps gears

one more potential possible source of metallic debris that could provide the cause of the cylinder bore damage
now if your building an engine you GOING TO DO FREQUENT OIL CHANGES ON AND NEVER LET SLUDGE BUILD UP...you can probably limit that potential valve train shrapnel screens and magnets that trap small destructive crud

When putting magnets in a steel oil pan, is there any need to use something
like JB Weld to hold them in place? Seems like they would stay on their
own, they are magnets.

the high temp magnets tend to stay right where they are placed, in a steel oil pan, but youll need J&B weld in an aluminum oil pan application,

jbweld_lrg.jpg

http://www.jbweld.com/faqs/
in my experience PROVIDED you use the ones designed to function in the heat range they can tolerate, just be aware you don,t want them too close to swinging oil baffle door flaps in a baffled oil pan as they have been known to hold those swinging gates open or closed if placed in the wrong areas,
example,
If this is an oil pan with this oil control baffle wall installed ,with steel oil control baffle doors, placing a magnet above these baffle doors is almost sure to prevent them from closing or placing one below is a sure way to keep them locked closed, thats one reason light weight ALUMINUM baffle doors are preferred,even in steel oil pans, the oil sloshing moves them, from open to closed as designed easily , limiting oil flow to movement in the direction desired, and magnets don,t tend to limit movement

I was just looking thru a magazine where they showed the result of a roller lifter that had failed and the tiny needle bearings dropped into the oil pan and got sucked up into the oil pump, which tried to pump those hardened steel roller bearings thru the gears but the clearances quickly locked the oil pump up and sheared the oil pump drive instantly resulting in zero oil pressure. thats a great way to point out the need for several items in your engine build, I know from lots of personal experience,disassembling engines,and rebuilding them, as I generally install magnets in every engine I build and so do most of my friends now, that a half dozen magnets will trap and hold an amazing amount of loose debris from ever reaching the oil pump... cam lobes wear as do lifters and rings, rockers etc. and wear is not something everyone can avoid, even an engine that seems to look pristine with no obvious wear will still have metallic dust collect on the magnets over time!
thats VERY COMMON, and even after you wash parts having a few magnets in the engine to trap random metallic crud helps.
any bearing failures are frequently or at least partly the result of micro crud being washed loose as parts wear,by hot oil and being embedded in bearings.

Grumpy you obviously can,t stick magnets to an aluminum oil pan so how do you use magnets

theres several routes that most guys use in that aluminum oil pan application,

use these, magnets linked above, in the lifter gallery and oil drain areas in the cylinder heads, and if you want too, the corners of the oil pan, the normal Neodymium magnets loose strength when subjected to high heat the ones listed ,especially the cobalt magnets are designed to operate under high heat conditions, you certainly don,t want metallic crap that was formally functional Neodymium magnets, that have lost the magnetism loose in the engine, you don,t need a great deal of pull strength, what you need is a way to trap and hold micro fine metallic crud from wear issues and preventing, that crap from getting embedded in bearings or causing wear in moving valve train components

but keep in mind metallic debris will travel thru the oil pump gears BEFORE it ever enters the oil filter so the guys that rely on an oil filter magnet alone don,t fully appreciate the damage some small hard and nearly indestructible metallic crud like busted valve keepers or loose and broken roller rocker needle bearings can do to an engine.
sbcoilh5a.jpg

sbcvsbbcgears.jpg

Shrapnel screens and magnets in the lifter gallery are a logical first line of defense.
a decent quality epoxy, LIKE J&B WELD will hold a magnet to the outside surface of each corner of the aluminum oil pan the magnetic field will still trap metallic crud inside the oil pan, but this means the oil pan must be removed to clean the trapped crud, if its first prepped with 180 grit sand paper in the attachment location and degreased with acetone, just be very sure its thermal characteristics and limitations have at least a 300F minimum threshold

Hi Grumpy,
I'm building a BBC and have read your threads & clicked your links on magnets & screens and there are a lot of different magnet types & sizes you've linked to.

Is there a list of the preferred sizes that correspond to their locations in the pan, the heads, lifter valley, etc. And any pictures of the preferred placement especially in the head drains?

Thanks

paint the cast surfaces

yes the stuffs expensive and high quality,
try to have a buddy go in for 50% of the cost,
a quarts easily enough for 5 -7 engines,
if you look at it, as a durability enhancement, thats less than $10 an engine
https://www.eastwood.com/glyptal-re...MIlvW7u4TQ4gIViLrACh0WFgRnEAQYAiABEgLLafD_BwE
glyptal.jpg

Ive used it and seen several other people use it , it works fine.
glyptal is used to seal in, micro surfaces and prevent fine metallic dust,
that might be present ,
even after a blocks been cleaned,
from getting into the oil flow circulating back to the oil pump,
if the blocks clean, grease free and dry when its applied ,
and if its left to dry over night it will not come off.

So one large 3" for the filter bottom, and 10 -1/2" wide by 1/4" thick, placing 4 in pan (1 each corner), 4 in lifter galley (1 in each corner), and 1 in each rear drain of heads?

Do I put the ones in the heads right on the middle or up on the side of the drain valley just before it goes down the hole?

I also saw some links to 1" by 1/4" are those preferred for the pan or lifter galley over the 1/2" wide?

Something like this, red ones in drain valley, green ones being overkill/optional?

magnet size is not all that critical, but get the high heat tolerant types linked, above ,
I generally use the 1" x 1/4" in the oil pan and lifter gallery and the, smaller 1/2" x 1/4" near the cylinder head oil drain back holes,
placed where oil draining back to the lifter gallery will run over them,you'll be amazed at the amount of metallic debris they catch.
read the link's on the shrapnel screens, and oil mods as thats also useful info.
the first time you tear down and inspect the crud trapped on those magnets, in an engine that has a few hundred hours of running time,
that was prevented from reaching the oil pump gears and bearings youll become convinced of the value

I put some magnets in the valley just under the drain back holes in the head. If you place them
here, be careful and don't get them too close the lifter bores. On cylinder #1 it grabs the lifter
every time I try to install it.

The magnets in the photo below were installed before I painted, so they should be the same
color as the valley ....silver. When you look at them without magnification, it just looks
like sludge, except for the one piece pointed to by the arrow. That one little piece, you will
see again in the 2nd photo below. What you see below is after 14,000 miles and I had already
started to wipe some off before I decided to take these photos.

While I had the heads and intake off, I wiped off the magnets and wiped it on another magnet
seen in the photo below. Now I could not get everything off the magnet in the valley by wiping
it by hand with a rag, so what you see is only about 60% of what was trapped. Photo below was
taken with 8X magnification and you can see the metal standing up.

Something like this, placing magnets and shrapnel screens helps engine durability red ones in drain valley, green ones being overkill/optional?


yeah thats logical magnet locations,
