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 for safety.

2. Clean the Area

Use a degreaser to clean the oil leak area to identify the source more easily.
Rinse off the degreaser and dry the area.

3. Inspect and Replace Gaskets/Seals

Valve Cover Gasket Replacement

Remove the engine cover if present.
Unscrew the bolts securing the valve cover and lift it off.
Remove the old gasket and clean the mating surfaces.
Install the new gasket and reassemble the valve cover with the specified torque (usually 7-9 lb-ft).

Oil Pan Gasket Replacement

Drain the engine oil from the oil pan.
Remove the oil pan bolts and carefully pry off the oil pan.
Clean the mating surfaces thoroughly.
Place a new gasket on the oil pan and reinstall it, tightening bolts to the specified torque (typically 12-15 lb-ft).

4. Replace Oil Filter and Drain Plug (if necessary)

If the oil filter is leaking, replace it with a new one.
Make sure to lubricate the rubber O-ring of the new filter with oil before installation.
Tighten the oil filter securely but do not overtighten.
Inspect the oil drain plug for wear and replace it if necessary.

5. Refill Engine Oil

Replace the oil drain plug if it was removed and refill the engine with the manufacturer-recommended oil.
Start the engine and let it run for a few minutes, then check for leaks.
