2002 Chevy Venture

Hi there,

There is no set mileage for an oil pump, you will have to consider a few factors first, mainly engine oil pressure, which is controlled mainly by the pressure relief valve and the condition of the engine bearings, the pump is a very sturdy item and will normally last the life of the engine, if you have low oil pressure problems and your oil pump is accessible you may prolong the life of the engine by replacing it.
