Checked my oil a few weeks ago and I saw a few very tiny specks of bright silver metal on my dipstick. There small you have to really look closely to even see them. Now the car runs as it always did with no weird noises or anything unusual. It seems like the more I pull the dipstick at once the more I see and my dipstick is very hard to put in and always scrapes the dipstick tube could the be what it is? My engine runs the same as always and the specks are very small and silver. Thanks in advance
