Carol S. Asks: Why Is My Oil Pan Rusted And Leaking? Can It Be Repaired?

Carol asked me how her oil pan in her Honda Civic became so rusted. Also she asked if it could be repaired. She asked me how an oil pan could rust because she was told that oil prevents rust on metal. How could this be? Well Carol the rust actually starts from the outside and eventually works its way in. It usually starts as a little stone chip in the paint on the oil pan. Then bare metal is exposed, then the metal oxidizes and rust eats its way in and eventually reaches the oil and then the leak starts. Can it be repaired? It would not actually be cost-effective to repair a rusted oil pan such as this, replacing the oil pan is the best choice. The oil pan shown is relatively inexpensive to replace because it is made of metal. Engine oil pans that are made of aluminum do not rust, however if an aluminum oil pan is damaged in any way it is more expensive to replace than that of an oil pan made of metal. So if you have an older vehicle and you are noticing new oil stains in your driveway it may me that your oil pan could be leaking. Oil leak or otherwise any fluid leak should be taken seriously and looked at as soon as possible by your mechanic. Thank you for your question Carol and thanks for visiting www.joeboulay.com
