Oil Pump: Inspection
WARNING: This page is about a different car, the 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.
Inspect components for damage. Measure rotor end play and outer rotor-to-housing clearance. Measure relief valve-to-bore clearance and relief valve spring tension. Replace oil pump assembly if measurements are not within specifications. See OIL PUMP SPECIFICATIONS table.
NOTE:
Oil pump is serviced as an assembly only. Replace assembly if measurements are not within specifications. See OIL PUMP SPECIFICATIONS table.
