b. Valve Cover Gasket

Sub-steps:
1. Remove any components obstructing access to the valve cover (e.g., intake manifold if necessary).
2. Unbolt the valve cover using a socket set and lift it off carefully.
3. Remove the old gasket material and clean the mating surfaces.
4. Install the new valve cover gasket and reposition the valve cover.
5. Torque the valve cover bolts to the manufacturer's specifications (usually around 7-10 ft-lbs).

c. Oil Pan Gasket

Sub-steps:
1. Drain the engine oil using an oil catch pan.
2. Remove the oil pan bolts and gently pry the oil pan off.
3. Clean the oil pan and engine block surfaces thoroughly.
4. Install the new oil pan gasket and reattach the oil pan.
