Solution

1. Preparation

Ensure the engine is cool before starting repairs.
Disconnect the battery to avoid any electrical issues.

2. Identify and Repair Oil Leaks

Inspect Gaskets and Seals:
- Remove any components obstructing access to the valve cover gasket.
- Visually inspect the valve cover gasket and other seals for cracks or wear.
- If damaged, replace the valve cover gasket.
Replace the Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of new oil to the rubber gasket of the new filter before installing.
- Install the new oil filter and tighten to manufacturer specifications.

3. Address Engine Overheating

Check the Cooling System:
- Inspect coolant levels; top off or replace if low.
- Look for any visible leaks in the hoses or radiator.
- Test the thermostat for proper function; replace if faulty.
Inspect Oil Quality:
- If the oil appears dirty or burnt, perform an oil change.
- Drain the old oil using a socket set and replace it with the manufacturer-recommended oil type and viscosity.
- Replace the oil filter again during this change.

4. Final Assembly and Testing

Reassemble any components removed during the inspection.
Reconnect the battery.
Start the engine and let it idle; check for any leaks or unusual noises.
