Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the battery to prevent any electrical issues.

2. Identify and Repair Oil Leaks

Inspect Valve Cover Gasket:
- Remove the engine cover (if applicable) using a socket set.
- Unbolt the valve cover and carefully lift it off.
- Inspect the gasket for cracks or wear.
- Clean the mating surfaces with a scraper and solvent.
- Replace the valve cover gasket with a new one and reassemble the valve cover, tightening the bolts to manufacturer specifications (typically around 10 Nm).
Check Oil Pan Gasket:
- Raise the vehicle using jack stands.
- Remove the drain plug and drain the engine oil into a container.
- Remove the oil pan by unbolting it carefully.
- Inspect the gasket and replace if damaged. Clean the oil pan and engine block surfaces before reinstallation.
- Reinstall the oil pan with a new gasket, torque bolts to specifications (typically around 20 Nm), and reinsert the drain plug.

3. Replace Oil Filter and Oil

Remove the old oil filter using an oil filter wrench.
Install a new oil filter, applying a small amount of new oil to the rubber gasket before installing.
Refill the engine with the correct type and amount of oil (typically 5W-30 or 5W-40 synthetic oil) as per the manufacturer’s specifications.

4. Final Checks

Start the engine and let it idle for a few minutes to check for leaks.
Monitor oil levels again after running the engine and top off if necessary.
