My poor baby just developed a rod knock. The noise usually is faint and only when accelerating slightly. I had one bout of very loud vibrating "humming" and clanking. I need to drive to NH from WY (2500 miles). Is there a chance this noise could be something else? How can I prolong the life of the car to get home? Any tips would be appreciated. I hear cars can last anywhere from 1 to 100,000 more miles with this issue. I am hoping for the latter. She's a 95 Saturn SL1 and I love her, but I understand her time has come.
