- Check for a damaged O-ring; replace the filter if necessary.
Valve Cover Gasket Replacement:
- Remove the bolts securing the valve cover using a socket set.
- Lift the valve cover off and replace the old gasket with a new one.
- Reinstall the valve cover and torque to the manufacturer's specifications (typically around 89 in-lbs).
Oil Pan Gasket Replacement:
- Drain the engine oil and remove the oil pan bolts.
- Carefully detach the oil pan and remove the old gasket.
- Clean the mating surfaces and install a new gasket.
- Reattach the oil pan and torque the bolts to the manufacturer's specifications (usually around 106 in-lbs).

3. Reinstall Components

Replace the oil filter by applying a small amount of oil to the new O-ring and tightening it by hand until snug.
Refill the engine with the appropriate type and amount of oil (typically 5W-20).
Reconnect the battery.
