Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Locate and Identify Leak Source

Remove any engine covers if necessary to access the oil filter and engine components.
Clean the area around potential leak points with a degreaser to make new leaks easier to spot.

3. Replace Gaskets or Seals

Oil Drain Plug:
- Use a socket wrench to remove the oil drain plug.
- Inspect the washer; replace if damaged.
- Reinstall the plug and tighten to the manufacturer’s torque specifications (typically 30 ft-lbs for RAV4).
Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with a little oil.
- Install the new filter, tightening it by hand until snug.
Valve Cover Gasket:
- Remove the bolts securing the valve cover, then carefully lift it off.
- Remove the old gasket and clean the mating surfaces.
- Place the new gasket in the valve cover and reinstall it, tightening to the specified torque (typically 10 ft-lbs).

4. Final Assembly

Reattach any components or covers that were removed.
Reconnect the battery.
Fill the engine with the appropriate type and amount of oil (typically 0W-20 for RAV4).
