I cut open the oil filter and wash the wear debris out of the filter element, How much iron dust/wear debris is normal in an oil filter ?

PS I sperate the iron wear debris with a magnet.

Should be almost none after the first oil and filter change.

Thanks for the input.

How much do you have? Let's see....you're having some oiling problems, so your going to a larger oil cooler and now finding metal in the filter? Might be more than just oil cooling issues. Is this the first oil change after building the engine? Did there appear to be any bearing material?

was this the first oil change on a new engine ? can you tell the material ??
