Q: Oil pump, replace or clean? I am installing a remanufactured engine?

asked by on

Does the oil pump get old and should I buy new for my new engine .

My car has 260000 miles.
My car has an automatic transmission.

You should look into buying a new one - especially with the age of your car. A used oil pump may not pump as good as a new one and may save you a lot of work if the used one fails.
