Solution

1. Preparation

Gather tools and materials before starting the repair.
Tools Required: Socket set, oil filter wrench, torque wrench, oil catch pan, rags, UV dye (if needed).
Safety Warnings: Ensure the engine is cool and the vehicle is on a flat surface.

2. Locate and Confirm the Leak

If the leak is from the oil filter:
- Sub-step 1: Use the oil filter wrench to remove the oil filter.
- Sub-step 2: Inspect the rubber O-ring on the old filter and ensure it came off with the filter.
- Sub-step 3: Install a new oil filter by applying a small amount of oil to the O-ring and tightening it to the manufacturer's specifications (typically hand-tight plus a quarter turn).
If the leak is from the drain plug:
- Sub-step 1: Position the oil catch pan under the oil pan.
- Sub-step 2: Use a socket wrench to remove the drain plug.
- Sub-step 3: Inspect the drain plug and gasket for damage; replace if necessary.
- Sub-step 4: Clean the area and reinstall the drain plug, tightening to the correct torque specification (typically around 20-25 ft-lbs).
If the leak is from the valve cover gasket:
- Sub-step 1: Remove any necessary components obstructing access to the valve cover.
- Sub-step 2: Remove the valve cover bolts using a socket wrench.
- Sub-step 3: Carefully lift the valve cover off and inspect the gasket.
- Sub-step 4: Replace the gasket and reassemble in the reverse order, ensuring proper torque on bolts (usually around 7-11 ft-lbs).

3. Add Oil

After repairs, refill the engine with the appropriate oil type as specified in the owner’s manual.
Use an oil funnel to prevent spills and check the dipstick to ensure proper level.
