Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off and cool.
Gather tools and replacement parts.

2. Identify Leak Source

Use a clean rag to wipe the engine area around suspected leaks.
Start the engine and observe for oil seepage at various points; this helps identify the exact source.

3. Replace Faulty Gaskets or Seals

Valve Cover Gasket Replacement

Disconnect the battery to prevent electrical shorts.
Remove any components obstructing access to the valve cover (e.g., air intake tube).
Unscrew the valve cover bolts (typically 10mm) and carefully lift the valve cover.
Remove the old gasket material from the valve cover and cylinder head surfaces.
Install the new gasket, ensuring it is properly seated.
Reinstall the valve cover and torque the bolts to the manufacturer’s specifications (usually around 7-9 Nm).

Oil Pan Gasket Replacement (if needed)

Drain the engine oil completely using an oil catch pan.
Remove the oil pan bolts and carefully detach it from the engine block.
Clean the mating surfaces thoroughly to remove old gasket material.
Apply a new gasket or gasket maker as required by the manufacturer.
Reinstall the oil pan and torque bolts to specified values (usually 8-10 Nm).
Refill the engine with oil and check the level.

4. Verify Repair

Start the engine and let it idle for a few minutes.
Inspect the previously leaking areas for any signs of oil leaks.
Check the engine oil level and top off if necessary.
