Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

- Remove any engine covers obstructing access.
- Unbolt the valve cover and carefully lift it off.
- Inspect the gasket for cracks or wear; replace if necessary.
Replace Gasket:
- Clean the mating surfaces with a gasket scraper.
- Apply a thin layer of RTV silicone on the new gasket if required.
- Reinstall the valve cover and tighten bolts to the manufacturer’s specified torque (usually around 7-9 ft-lbs).

3. Check and Replace Oil Filter

Inspect Oil Filter:
- Locate the oil filter and check for leaks.
Replace Oil Filter:
- Use an oil filter wrench to remove the old filter.
- Lubricate the rubber gasket of the new filter with fresh oil.
- Install the new filter and tighten it by hand until snug.

4. Inspect and Repair Oil Pan

Check Oil Pan:
- Inspect the oil pan for cracks or loose bolts.
Repair or Replace:
- If damaged, drain the oil and remove the oil pan.
- Replace the oil pan gasket and reassemble, ensuring all bolts are torqued correctly.

5. Refill Engine Oil

After completing repairs, refill the engine with the appropriate grade of oil (consult owner’s manual, usually 0W-20 for RAV4).
Start the engine and let it idle for a few minutes, checking for any leaks.
