Raise the vehicle using a jack and secure it with jack stands.

2. Identify the Leak Source

Clean the engine and surrounding areas with degreaser to eliminate old oil.
Use a UV dye in the engine oil, run the engine, and then inspect with a blacklight to pinpoint leaks.

3. Replace Faulty Components

A. Oil Filter

Tools Required: Oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it to hand-tight plus a quarter turn.

B. Valve Cover Gasket

Tools Required: Socket set, torque wrench, gasket scraper
Remove the valve cover by loosening the bolts in a crisscross pattern.
Carefully lift off the valve cover and remove the old gasket.
Clean the mating surfaces with a gasket scraper to ensure a good seal.
Install the new gasket and reattach the valve cover, tightening bolts to the manufacturer’s specification (usually around 7-9 ft-lbs).

C. Oil Pan Gasket (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the engine oil using an oil catch pan.
Remove the oil pan by loosening the bolts and gently prying it off.
Clean the surface of the oil pan and engine block with a gasket scraper.
Install a new gasket and reattach the oil pan, tightening bolts to the manufacturer’s specification.

4. Refill Engine Oil

Refill the engine with the appropriate type and amount of oil as per the owner's manual.
Start the engine and let it idle for a few minutes while checking for leaks.
