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 ensure safety during repairs.

2. Identify and Repair Leaks

Inspect Seals and Gaskets
- Remove engine covers if necessary for better access.
- Check the valve cover gasket and oil pan gasket for signs of wear or damage.
- If found damaged, proceed to replace the gasket.
Replace Worn Gaskets
- Tools Required: Socket set, gasket scraper, torque wrench
- Remove the bolts securing the valve cover or oil pan, depending on the location of the leak.
- Clean the mating surfaces of old gasket material using a gasket scraper.
- Apply a new gasket and reassemble. Torque the bolts to the vehicle manufacturer's specifications.
Check Oil Filter
- Inspect the oil filter for leaks or loose fittings.
- If loose, tighten it; if damaged, replace it with a new filter.

3. Check Oil Level and Quality

Add Oil if Necessary
- If oil is low, add the appropriate type and grade of oil as specified in the owner's manual.
- Check for any contaminants in the oil that might indicate internal engine issues.
