Whining noise from oil pump on Mitsubishi Eclipse

On 2.4L 4 cylinder engines a whining noise may be noted when the engine is cold and the rpm is in the 1800-2000 range. Our technicians tell us that most commonly this type of noise is coming from the engine oil pump. The repair is to replace the front case assembly and both the drive and driven oil pump gears.
