Magnets in the motor, That's what I do! Options

[Mark Henry]

I've heard some people say you shouldn't put magnets in a motor, their logic is it could magnetize the steel parts.

I've always call BS on this.
Porsche /6 has a magnet on the drain plug, the trans has a magnet on the drain plug, on all the big type 1 with oil sumps I've built I've put a big frick'in cow magnet in them.

No matter how spotless I got the engine, after break in I always see a fine amount of metal filing fuzz on the magnet.

The type 4 was a challenge, where to put the magnet?


My solution is to epoxy two magnets to the bottom of the sump screen. I take two 1/4" X 1/8" rare earth magnets and epoxy them to the bottom of the sump screen.if you place them where the spring backs up they stay put till the epoxy cures. The 3rd magnet in the pic (the clean one) is just to show you the placement and magnet. I don't know if you can see the slight fuzz of metal filings.
To me it's better they are on the magnet, than through the pump.
And what happens if the filter bypass opens?
