2. Loosen and remove the bolts securing the valve cover using a socket set.
3. Carefully lift the valve cover off and inspect the old gasket for wear or damage.
4. Clean the mating surfaces thoroughly to ensure a proper seal.
5. Install a new gasket and reattach the valve cover, torquing the bolts to manufacturer specifications.

4. Inspect and Replace Oil Pan Gasket

Sub-steps:
1. Raise the vehicle securely using jack stands and remove the undercarriage protection if installed.
2. Drain the engine oil by removing the drain plug and allowing the oil to flow into a suitable container.
3. Remove the bolts securing the oil pan and gently tap it loose to break the seal.
4. Clean the oil pan and engine block mating surfaces thoroughly.
5. Install a new oil pan gasket and reattach the oil pan, ensuring the bolts are tightened to the specified torque.
