Disconnect the battery to avoid any electrical issues.

2. Locate and Fix the Leak

a. Oil Filter Replacement

Tools Required: Oil filter wrench, oil catch pan, funnel
Remove the old oil filter using the oil filter wrench. Make sure to have the catch pan underneath to collect any residual oil.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, tightening it according to the manufacturer’s specifications.

b. Drain Plug Inspection

Tools Required: Socket set, torque wrench
Place an oil catch pan under the oil pan and remove the drain plug with the socket set.
Inspect the drain plug for cracks or damage. Replace if necessary.
Clean the area around the drain plug hole and re-install the plug, tightening it to the manufacturer's torque specifications.

c. Gasket and Seal Replacement

Tools Required: Gasket scraper, RTV silicone, torque wrench
For leaking valve cover gaskets, remove any components obstructing access.
Remove the valve cover bolts and lift the cover off. Scrape off any old gasket material.
Apply a new gasket or RTV silicone as per manufacturer recommendations, and re-install the valve cover with bolts tightened to specified torque values.

3. Refill Engine Oil
