Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool before proceeding.
Disconnect the battery to prevent electrical issues.

2. Identify and Fix Leaks

Inspect oil filter and drain plug:
- Tighten the oil filter and drain plug if loose.
- Replace the oil filter if it shows signs of wear.
Check oil lines and seals:
- Visually inspect all oil lines for cracks and wear.
- Replace any damaged oil hoses or gaskets.

3. Clean Affected Areas

Use degreaser and rags to clean any oil residue from the engine and surrounding areas.
Ensure all surfaces are dry to prevent further oil accumulation.

4. Refill Engine Oil

If the oil level was low, refill the engine with the recommended oil type (check owner's manual for specifications).
Start the engine and allow it to reach operating temperature, then check for leaks again.

5. Final Assembly

Reconnect the battery.
Replace any engine covers or components that were removed for inspection.
