Solution

1. Preparation

Gather 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 during the repair.

2. Identify and Fix the Leak Source

2.1. Oil Filter Replacement

Tools Required: Oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench.
Make sure the rubber gasket from the old filter is not stuck on the engine.
Lubricate the gasket on the new filter with a little fresh oil.
Install the new oil filter and tighten it by hand until snug.

2.2. Drain Plug Inspection and Replacement

Tools Required: Socket set, torque wrench
Place an oil catch pan under the oil pan.
Remove the drain plug using a socket wrench; allow oil to completely drain.
Inspect the drain plug gasket; replace if damaged.
Reinstall the drain plug and tighten it to the manufacturer’s specified torque (typically around 30-35 ft-lbs for most Toyota models).

2.3. Gasket Replacement (if necessary)

Tools Required: Gasket scraper, torque wrench
If the oil leak is from the valve cover or oil pan gasket, remove any components obstructing access.
Remove the old gasket using a gasket scraper, ensuring the surface is clean.
Place the new gasket in position and reassemble the components.
Torque bolts to the manufacturer’s specifications (consult repair manual for exact values).

3. Refill Engine Oil

Tools Required: Funnel
Refill the engine with the appropriate type and amount of oil, as per the manufacturer’s specifications (typically 0W-20 for the RAV4).
Check the oil level with the dipstick and adjust if necessary.
