does filtermag really work? here's the proof

[INSIDIOUS '86]

note:my engine has about ten thousand miles on it, was broke in with break in oil and moly/graphite grease on all surfaces when put together ran 1000 miles on castrol with a wix filter and has a non bypass pickup, it has been running royal purple since the first thousand mile break in with k&n filters, ran a filter mag for one week proir to changing my oil also note interior of block is coated in glyptal


not that my drain plug is also magnetic so it catches metal particles as well
so needless to say my engine is hardly worn and very clean

heres the evidence
I cut into a full of oil K&n hp3002 filter

larger particles shown are from sawzall
my procedure was as following pull filter mag off (shoulda prob left it on)
clamp in vise and cut. reinstall filter mag in same exact place
drain into pan while swirling to recapture any particles

Nice work if you plan on cutting open a few try a oil filter cutter http://www.summitracing.com/parts/SUM-900510/?rtype=10

defently need a filter cutter, it would be enterest'n to see what it picks up with out the sawzall debri.

I bet a guy could make a filter cutter out of a can opener or tubing cutter. I once made a valve spring compressor out of a bicycle training wheel bracket and it works great.

well my engine is so clean still that it really didnt pick up much, but the black stuff is micro particles ie metal sludge

[asphaltburner]

Damn,...hope I don't ever have ANY metal debris in my filter!

you will always have small amounts of metal particles in engines new or old, especialy old

and the filter will not catch it either

[asphaltburner]

Only if you're tearing it up.

Agreed. Filter and drain plug magnets are a good idea because they're cheap, easy, and won't hurt anything. Magnets in the tranny and axles helps too. The big three added magnets to axles and trannys sometime in the late 80s or early 90s... The iron fur on the axle magnet in my GMC was scary. I added rare earth magnets to the axles in my 76.

Those deposits on the magnet are NOT normal after breakin. That is usually cam wear but can be other sources. If they did that every time you changed oil, you wouldn't have some part of the engine very long.
I built engines since 1960 and my engines do not do that!!!
Regular Royal Purple may not protect your cam with enough ZDDP.

Normal metal wear in an engine that would end up in the oil should not be visible to the naked eye. If you can see it then I would say there is a problem.

the black stuff is hardly visable so the only way i know its metal is the fact its sticking where the magnet is, if i didnt use a sawzall that would be the only evidence of any small metal particles

its possible that it doesnt but i did have my cam nitrided by comp cams beore installation, they say that alone will do fine, so far after many many 7k blast down the track ive had the top end off and it looks new still
I would recomend having your cams nitrided!

this is quite common, I guess they also put magnets in trans pans as well
around that time but the metal fur on the rear axles is always scary looking!
