Oil Pump: Inspection
- Inspect oil pump housing for cracks or damage. Ensure relief valve slides smoothly in bore. Inspect pressure relief spring for damaged coils.
- Inspect oil pump gears for wear or damage. Using a feeler gauge, measure radial and side clearance. If clearance exceeds specification, replace outer gear rotor or case. See the OIL PUMP SPECIFICATIONS table below.
