211º Posted July 5, 2020 Report Share Posted July 5, 2020 My wife gave me a GoPro for my birthday... so I've been making some videos. This short-ish video shows what I do once I get the actual filter out of the filter casing. 3 Quote Link to comment Share on other sites More sharing options...
PTK Posted July 5, 2020 Report Share Posted July 5, 2020 You can wash the filter element really well in a small bucket with mineral spirits. Then put a strong enough magnet under the bucket and decant the liquid while gently agitating it. Anything left on the bottom of the bucket has to be ferrous material and can be easily quantified. 2 Quote Link to comment Share on other sites More sharing options...

I've always thought that (for the most part) flecks are (relatively speaking) normal wear and tear - unless there is an amount that could be seen/gathered in a teaspoon. And slivers are pieces of metal being shaved (stripped?) from the cam-shaft and indicate that the cams are getting past the very hard (and thin) protective metal/layer. I'm open to hearing more/other opinions. 1 Quote Link to comment Share on other sites More sharing options...

Thanks much. I also appreciated seeing the photo with slivers in it - lots of slivers - just as a comparison of how bad it could be. Quote Link to comment Share on other sites More sharing options...
