I have a new 2022 4Runner with 500 miles on it. I decided to change the oil at 500 miles to help get rid of any debris from the engine breaking in. When I went to check the level of the oil after refilling it, I noticed there were some metal shavings on the tip of the dip stick. After fooling around with it and inserting it and removing it, I concluded that the dip stick was scraping the inside of the dipstick tube as it was snaking it’s way through it. I took some 2000 grit sand paper and smoothed the edges of the tip of the dipstick and now it inserts much smoother and got rid of the metal shavings I was seeing.
My question is could the shavings from the inside of the dipstick tube cause any harm to my engine? It took me a few tries of inserting and removing the dipstick to figure out what was happening so I’m sure I got some of the small metal shavings into the oil pan. I’m assuming the pick up tube strainer would catch anything too large and the oil filter would catch the rest however what about the oil pump? My understanding of the 1gr-fe is that the oil flows through the oil pump prior to the oil filter. Can oil pumps tolerate small metal debris in the oil?
These pictures aren’t mine but they look almost identical to the metal shavings I was getting on the tip of my dip stick.
