Solution

1. Preparation

Tools Required: Oil catch pan, socket set, torque wrench, clean rags, engine degreaser.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Drain Oil

Place the oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the drain plug and torque it to the manufacturer's specifications.

3. Replace Oil Filter

Locate the oil filter, usually at the bottom of the engine.
Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket on the new filter.
Install the new oil filter, tightening it by hand until snug.

4. Address Gasket Seals

Valve Cover Gaskets:
- Remove any components obstructing access to the valve covers (e.g., air intake duct).
- Unbolt the valve cover using a socket set, clean the mating surfaces, and replace with new gaskets.
- Reinstall the valve cover and torque the bolts to the specified value.
Crankshaft Seals:
- For the front crankshaft seal, remove the timing belt/chain cover to access the seal. Replace if leaking.
- For the rear crankshaft seal, removal of the transmission may be necessary; consult repair manual for specific procedures.

5. Refill Oil

Refill the engine with new oil through the oil filler cap.
Use the recommended oil type and capacity as per the owner’s manual.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes while checking for leaks.
Inspect all areas previously worked on to ensure there are no leaks.
