- Oil filter wrench
- Screwdrivers
- Cleaning rags
Safety Warnings:
- Allow engine to cool before starting work.

2. Identify and Repair the Leak Source

a. Oil Pan Gasket Replacement

Remove the drain plug and drain the oil into a suitable container.
Remove the oil pan by unscrewing the bolts using a socket set.
Clean the mating surfaces thoroughly with a scraper and solvent.
Install a new oil pan gasket and reattach the oil pan, torqueing the bolts to the manufacturer's specifications (typically around 8-10 ft-lbs).

b. Valve Cover Gasket Replacement

Remove any components obstructing access to the valve cover (e.g., air intake duct).
Unscrew the valve cover bolts and gently lift the valve cover off.
Remove the old valve cover gasket and clean the mating surfaces.
Install the new gasket, ensuring proper alignment, and reattach the valve cover, torquing the bolts evenly (typically around 7-9 ft-lbs).

c. Oil Filter and Drain Plug Inspection

Inspect the oil filter for signs of leaking; replace if necessary.
Replace the oil filter using the oil filter wrench, ensuring the rubber O-ring is lubricated and seated properly.
Reinstall the drain plug with a new washer if necessary, torquing to the manufacturer’s specifications (typically around 20-25 ft-lbs).
