5. Ensure no oil is leaking from the filter.

4. Inspect and Replace Oil Pan Gasket (if necessary)

Sub-steps:
1. Drain the engine oil into the catch pan by removing the drain plug with a socket.
2. Remove the oil pan bolts and gently pry the oil pan away from the engine block.
3. Clean the mating surfaces thoroughly.
4. Install a new gasket and reattach the oil pan, torquing bolts to specifications.
5. Reinstall the drain plug and refill the engine with new oil per manufacturer recommendations.
