I drive a 1994 Bonneville. The head on my oil dipstick recently broke off, so I went to the local pull apart, found a car with the same engine as mine, and pulled the dipstick. I was talking to someone who said that I could have just bought a new dipstick from Advanced Auto Parts (or similar store). How do I know if this is true (and will not damage my car). If this is a duplicate post, please direct me to the original, Thanks!
