My car was diagnosed of oil leaking from the vacuum pum. The mechanic told me to replace it with few other oil seal, O ring etc. My main concern in the vacuum pump. Having second opinion for another mechanic and was told that it can be repaired in of replacing which is costly (I know that as I am also survey of the price). He said it leak can be attended too and give warranty 3 months. I know that replacing it would be the best choice but what do you guys think of repairing it. Have any of you done so and does it works and what is the life span?Thanks
