Identify which gasket or seal is leaking (e.g., valve cover gasket, oil pan gasket).
Remove components that obstruct access to the gasket (e.g., air intake, engine covers).
Remove the old gasket or seal using a gasket scraper, ensuring the surface is clean.
Apply a thin layer of gasket maker (if applicable) on the new gasket and install it.
Torque the bolts to the manufacturer's specifications (refer to a service manual for exact torque values).

4. Tighten Oil Filter and Drain Plug

Tools Required: Oil filter wrench, socket set
Tighten the oil filter to the specified tightness, ensuring it is secure.
Check the drain plug for tightness and replace the washer if necessary.

5. Refill Engine Oil

Check the oil level after repairs using the dipstick.
Add the appropriate type and amount of oil as specified in the owner’s manual.

6. Clean Up

Clean any spilled oil and dispose of materials properly.
Start the engine and observe for leaks, ensuring all components are secure.
