K&J Magnetics - Products this could be overkill i guess, they have other options. Great site! I wonder how strong it really is, the axial force seem's it would be best for this application(attached to drain plug/or filter)
There's also no real evidence that they help or make a difference.<--Link to this same question I posed to Tom & Ray at Car Talk a couple years ago.
a diffrence in what way? Magnet would not be for MPG< but for any engine gunk car has low miles, probably some metal floating around in there! 175 force pound might drive the dealer nut's though
I use a very strong one on the oil filter. Can't hurt. The magnetic plug on the CVT trans held a nice layer of metallic sludge on it when I removed it at 6K so thats working OK there. Guess I'll cut off the bottom of the oil filter next go round and see what its doing.
I drilled out the drain plug and pressed a pretty strong magnet into the hole ... and for good measure shmeared a little loctite 609 on both surfaces ... just in case the ICE vibration was more than the press fit. But THAT magnet you're showing? ... is WAY too klunky to fit into a drain plug ... and no way am I opening up the pan, just to put a magnet in it. As efusco says, the whole magnet thing is iffy anyway.
well it was just going to attach it to the outside of the plug. Which should draw particles toward's the nose of the plug.
A lot of commercial and industrial equipment have magnets in the sumps. The theory here is that one can expect metal slivers/shavings especially after major service like a bearing replacement, and the magnets protect other components Some civillian vehicles have oil sump magnetic drain plugs, some don't. My 2000 GMC Sierra had a magnet on the drain plug, and that thing was always hairy with slivers Based on my used oil analysis with the oil and filter run up to 16,000 km, I see no evidence of metal. I've taken apart a couple of the filter too, no evidence of metal
