- Remove engine covers if necessary.
- Check for oil seeping around the edges of the valve cover.
Replace Valve Cover Gasket:
- Remove bolts securing the valve cover using a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces with a gasket scraper and solvent.
- Place the new gasket onto the valve cover, ensuring it is seated properly.
- Reinstall the valve cover and torque bolts to manufacturer specifications (typically 7-9 ft-lbs).

3. Check and Replace Oil Filter

Inspect Oil Filter:
- Locate the oil filter and check for leaks.
Replace Oil Filter:
- Use an oil filter wrench to remove the old filter.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new filter by hand until snug, then tighten it according to the manufacturer's specifications.

4. Address Oil Pan Leak (if necessary)

Inspect Oil Pan Gasket:
- Check for oil leakage around the oil pan.
Replace Oil Pan Gasket:
- Drain the engine oil using an oil pan and remove the oil drain plug.
- Remove the bolts securing the oil pan and gently pry it off.
- Clean the mating surfaces of the oil pan and engine block.
- Install a new gasket and carefully reattach the oil pan, ensuring it is properly torqued.
