Solution

1. Preparation

Gather necessary tools and materials.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery to avoid electrical issues during repair.

2. Drain Oil

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench (typically 10mm).
3. Allow oil to completely drain into the pan.
Tools Required: Socket wrench, drain pan.

3. Replace Gaskets or Seals

Sub-steps:
1. If the oil leak originates from the oil filter, remove it using an oil filter wrench and replace it with a new one.
2. For the oil drain plug, replace the washer if damaged and reinstall the plug with a torque of 25 ft-lbs.
3. If the valve cover gasket is leaking, remove the valve cover by unscrewing the bolts and gently lifting it off. Clean the mating surfaces and install a new gasket before re-securing the cover with a torque of 7 ft-lbs.
4. For the oil pan gasket, remove the oil pan by unscrewing the bolts and gently prying it off. Clean the old gasket material from both surfaces, apply a new gasket or RTV sealant, and reattach the oil pan with a torque of 10 ft-lbs.
Tools Required: Oil filter wrench, socket set, torque wrench, gasket scraper.

4. Refill Oil

Sub-steps:
1. Replace the oil drain plug once the oil has drained completely.
2. Refill the engine with the manufacturer-recommended oil type and quantity (typically 0W-20 for RAV4).
3. Start the engine and let it run for a few minutes, checking for leaks around replaced components.
Tools Required: Funnel, oil container.
