Dilitium Crystals!! Bwahaha!! (I actually have a parts drawer at work labeled Dilithium Crystals)... Holds spare batteries for our small manufacturing faclilty.dilithium crystals?? kidding aside.. wtf are those.. one piece on top looks like a piece of sleeve or bearing.. wait for others to chime in..
Not a bad idea. I have some paint style disposable filters that I could strain the next dump through. I could drain & strain into a clean container then pour back in a few times to see if more junk comes out.That is concerning. If I found something like that I would take a short ride after the oil change and change the oil again.
