I took the car out the other day and it drove fine. I later come home and i smell something a little funny. So i check it out and i see the car is leaking some oil. Not a whole lot but more then i feel comfortable with. So i get under then clean it all up and start the car and i see it dripping from the when the oil filter, and sending unit are. Then i notice that there is a small pin hole where it is coming out from. Has anyone had this happen or what may have caused this?
