I'm looking for a ferrous metal top for the oil filter housing (something a magnet will stick to). Does anyone know if such a thing exists in the aftermarket?? The reason I want one is so that I can stick a strong magnet to it which would help remove small ferrous particles from the oil. I've run a magnet on the canister style oil filters of pretty much everything I've owned for several years and they do help. Every oil filter I've cut apart has some junk gathered around the magnets location. I run a fomoto valve on the 6.4 oil pan drain so a magnetic oil drain plug is out. And with the element style filter that leaves me nowhere to put the magnet, unless someone out there makes a ferrous metal oil filter housing lid. Any thoughts?????
