It says: "Pulls metal particles from your engine." :icon_eek: Do we expect metal particles be in the engine? If that is the case then you have far more serious issue than just collecting them.Anyone have thoughts on whether or not this is a good idea?
Hard drive magnets are very strong but they may lose their magnetic properties when exposed to heat. All magnets do - it's called the Curie effect - but some formulations are more resistant to heat than others. I don't know how the rare-earth magnets inside a hard drive will be affected by engine temps but it is something to keep in mind. Plus, they are usually quite brittle and nickel plated. If some of that stuff breaks off it could get into the oil stream.or just take apart a hard drive you don't use anymore and throw one or two of those magnets in there.....they some strong magnets.
