Park the vehicle on a level surface and allow the engine to cool completely.
Disconnect the battery to avoid any electrical issues while working.

Tools Required:

Socket set
Torque wrench
Oil catch pan

2. Identify and Replace Leaking Gasket or Seal

Sub-step 1: If the leak is from the valve cover gasket:
- Remove the engine cover if present.
- Unscrew and remove the valve cover bolts.
- Carefully lift the valve cover and replace the old gasket with a new one, ensuring it is seated properly.
- Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically around 7-10 ft-lbs).
Sub-step 2: If the oil pan gasket is leaking:
- Drain the engine oil into the catch pan.
- Remove the oil pan bolts and gently pry the oil pan off.
- Clean the mating surfaces thoroughly and install a new gasket.
- Reassemble the oil pan and torque bolts to manufacturer specifications (typically around 8-12 ft-lbs).
Sub-step 3: If the leak is from the oil filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a small amount of oil to the rubber gasket of the new filter.
- Install the new oil filter, tightening it by hand until snug.

3. Refill Engine Oil

Ensure all components are reassembled correctly.
Refill the engine with the appropriate type and amount of oil as per the owner’s manual (typically 0W-20 for the RAV4).

4. Clean Up

Clean any spilled oil and dispose of the old oil and filter properly.
Reconnect the battery.
