Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check and Change Engine Oil

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the drain plug using a socket set and drain the old oil into a pan.
3. Replace the oil filter using an oil filter wrench, ensuring the old rubber o-ring is removed.
4. Install the new oil filter and torque it to the manufacturer's specifications (usually around 18-25 Nm).
5. Reinstall the drain plug and torque it to the proper specification (typically 30-40 Nm).
6. Refill the engine with the recommended oil type (check owner's manual for specifications).

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by unbolting it and carefully separating it from the engine block.
2. Inspect the oil pump for any signs of wear or damage.
3. If necessary, remove the oil pump by unbolting it from the engine block.
4. Install the new oil pump, ensuring all seals and gaskets are properly aligned.
5. Reinstall the oil pan with a new gasket, ensuring it is torqued to the manufacturer's specifications.

4. Verify Oil Pressure

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle.
3. Use the mechanical oil pressure gauge to verify that oil pressure is within the specified range (consult service manual for values).
4. Monitor for any leaks around the oil filter, oil pan, and oil pump.
