Don't drive my car much, took it out tonight and starting getting on highway went from 3rd to 4th about 65mph and I hear a pop and knocking starts like crazy I coast off the exit ramp and pull into a wendy's. See a trail of oil from the car and I can't see under it. Im having it towed home now, gonna put it up on stands to see. It only has 24k miles on it and they aren't hard miles, any thought on what it could be? Thrown rod? If so is that a total engine replacement? FUDGE!!!! I am devastated !
