Thread: OiL Filter Magnet

Tweet

If there are filings in the engine, the pump is the first thing they pass through on the way back to lubing the engine. I don't see a magnet catching every particle in the oil as it passes by it. Oil is designed to suspend particles and the oil is moving past the magnet fairly fast. Best way to remove the particles is a tear down. IMHO.

I see what you mean. Thanks for the solid.

I can see some value in a magnet on a fresh rebuild, to catch the fine stuff caused by the breaking-in process.

Your local ranch supply store will supply you with cow magnets (drop in magnets) for about 50 cents each. I don't use them because the ferrous materials have already gone through the pump causing damage and if the filter is doing its job the crap is going no further.
I drop a two"x 1/4" in the pan in front of the pickup on rebuilds and a magnetic drain plug. If the plug has more than just a bit on it I start saving for the next rebuild.
